Chloramine has the chemical formula NH,CI. Nitrogen has five valence electrons, each hydrogen has one valence electron, and chlorine has

seven valence electrons. Complete the Lewis structure for this covalent compound.

Answers

Answer 1

Answer:

A lewis structure shows the electrons on the valence shell of a molecule as dots.

Explanation:

A lewis structure refers to a structure in which dots are used to represent the electrons present on the outermost shells of the atoms comprising the bond. So stones a line is used to show a pair of electrons shared by two atoms in a covalent bond.

This system was put toward by Sir G.N Lewis in 1916 in his article titled, 'The atom and the molecule'. Lewis structures are based on the octet rule.

The image attached shows the lewis structure of chloramine. All the electrons present on the valence shell of all the bonding atoms is adequately shown in the image. There are fourteen valence electrons in the molecule as shown in the diagram. Recall that chlorine has seven valence electrons, nitrogen has five and each hydrogen atom has one valence electron each. The three lone pairs on the chlorine atom and one lone pair on the nitrogen atom is clearly shown in the image.

In a single displacement reaction between sodium phosphate and barium, how much of each product (in grams) will be formed from 10.0 grams of barium?

Answers

Answer:

A. 3.36g of Na.

B. 14.62g of Ba3(PO4)2.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

3Ba + 2Na3PO4 → 6Na + Ba3(PO4)2

Next, we shall determine the mass of Ba that reacted and the mass of Na and Ba3(PO4)2 produced from the equation.

This is illustrated below:

Molar Mass of Ba = 137g/mol

Mass of Ba from the balanced equation = 3 x 137 = 411g

Molar mass of Na = 23g/mol

Mass of Na from the balanced equation = 6 x 23 = 138g

Molar mass of Ba3(PO4)2 = (3 x 137) + 2[31 + (4x16)] = 411 + 2[31 + 64] = 601g/mol

Mass of Ba3(PO4)2 from the balanced equation = 1 x 601 = 601g

Summary:

From the balanced equation above,

411g of Ba reacted to produce 138g of Na and 601g of Ba3(PO4)2.

A. Determination of the mass of Na produced by reacting 10g of Ba.

From the balanced equation above,

411g of Ba reacted to produce 138g of Na.

Therefore, 10g of Ba will react to produce = (10 x 138)/411 = 3.36g of Na.

Therefore, 3.36g of Na is produced.

B. Determination of the mass of Ba3(PO4)2 produced by reacting 10g of Ba.

From the balanced equation above,

411g of Ba reacted to produce 601g of Ba3(PO4)2.

Therefore, 10g of Ba will react to produce = (10 x 601)/411 = 14.62g of Ba3(PO4)2.

Therefore, 14.62g of Ba3(PO4)2 is produced.

Consider this hydrocarbon. A hexagon. Is this an aromatic hydrocarbon? Why or why not? Yes, because the carbon chain is made up of single bonds. Yes, because the carbon chain is ring shaped. No, because the carbon chain is composed of only a single ring. No, because the carbon chain has no double bonds.

Answers

Answer:

C. No, because the carbon chain is composed of only a single ring.

Polycyclicity, having more than a single ring, is a property of only aromatic hydrocarbons. Therefore, if the hydrocarbon is not polycyclic, it is non-aromatic

Explanation:

Cyclic Hydrocarbons

These are organic compounds which are cyclic in structure. The compound cyclohexane involves a ring of six carbon atoms, each of which is also bonded to two hydrogen atoms

Aromatic hydrocarbons are cyclic ring organic compound which are based on the benzene ring structure.

A. If the hexagon contains single bonds, it is non-aromatic.

B. No. Having a ring shape does not on its own determine the aromaticity of a hydrocarbon.

C. Polycyclicity, having more than a single ring, is a property of only aromatic hydrocarbons. Therefore, if the hydrocarbon is not polycyclic, it is non-aromatic

D. Having double bonds within a ring is not a criteria for being aromatic. Both aromatic and non-aromatic hydrocarbons have double bonds within their rings. However, aromatic hydrocarbons have alternate double and single bonds within their 6-carbon ring structure.

Note: Since the structure of the required hydrocarbon is not shown, the explanation contains attachments of hexagonal structures of three hydrocarbons; one non-aromatic and the other two are aromatic. Cyclohexane is non-aromatic while Benzene and the polycyclic compounds are aromatic.

Answers

Answer:

According to A pex, the answer is B.

Explanation:

Because its right.

When one reactant breaks down to form more than one product is a decomposition reaction. Therefore, option (B) is correct.

What is a decomposition reaction?

A decomposition reaction can be described as a reaction in which a compound breaks down into two or more simpler compounds. The general form  to represent a decomposition reaction is:

AB  →   A   +  B

Most decomposition reactions need input energy in the form of light, heat, or electricity.

Binary compounds can be described as compounds made of just two elements. The simplest type of decomposition reaction is when a binary compound dissociated into its elements. For example, Mercury (II) oxide decomposes when heated to form mercury and oxygen gas.

2HgO(s)    →   2Hg  (l)   +  O₂(g)

A reaction is a decomposition reaction even when one or more of the products are compounds. For example, calcium carbonate decomposes into carbon dioxide gas and  calcium oxide.

12. How many grams of glucose (C6H1206) is produced if 17.3 mol of H20 is reacted according to this
balanced chemical equation? 6CO2 + 6H20 - C6H12O6 + 602
13. Nitroglycerin (C3H5(ONO2)3] is made by reacting nitric acid (HNO3) with glycerol [C3H5(OH)3]
according to this reaction:
C3H5(OH)3 + 3HNO3 - C3H5(ONO2)3 + 3H20
If 87.4 g of HNO3 is reacted with excess glycerol, what mass of nitroglycerin can be made?

Answers

Answer:

1. 17.3 MOLES OF WATER WILL PRODUCE 518.4 G OF GLUCOSE.

2. 87.4 G OF HNO3 WILL PRODUCE 7.86 G OF NITROGLYCERIN WHEN REACTED WITH EXCESS GLYCEROL.

Explanation:

1. How many grams of glucose is produced from 17.3 mole of water?

Equation:

6CO2 + 6H20 ------> C6H12O6 + 6O2

From the reaction, 6 moles of carbon dioxide reacts with 6 moles of water to produce 1 mole of glucose

So therefore,

6 moles of water = 1 mole of glucose

Since 17.3 mole of water was used, we can first calculate the number of moles of glucose produced:

Then, we have:

6 moles of water = 1 mole of glucose

17.3 moles of water = ( 17.3 * 1/ 6) moles of glucose

= 2.883 moles of glucose

So we say 17.3 moles of water produces 2.883 moles of glucose

At standard conditions, 1 mole of a substance is its molar mass

Molar mass of water = 18 g/mol

Molar mass of glucose = 180 g/mol

From the reaction:

17.3 moles of water produces 2.883 moles of glucose

17.3 * 18 g of water produces 2.833 * 180 g of glucose

= 518.94 g of glucose.

From 17.3 mole of water, 518.4 g of glucose will be produced.

2.

C3H5(OH)3 + 3HNO3 -------> C3H5(ONO2)3 + 3H20

3 moles of HNO3 reacts to produce 1 mole of nitroglycerin

Molar mass of HNO3 = ( 1 + 14 + 16*3) = 63 g/mol

Molar mass of nitroglycerin = ( 12 *3 + 1 *5 + 16*6 + 14*3) = 179 g/mol

3 moles of HNO3 = 1 mole of nitroglycerin

3 * 63 g of HNO3 = 179 g of nitroglycerin

if 87.4 g of HNO3 were to be reacted, we have:

189 g of HNO3 = 179 g of nitroglycerin

87.4 g of HNO3 = ( 87.4 * 179 / 189) of nitroglycerin

= 7.86 g of nitroglycerin

So therefore, 87.4 g of HNO3 will produce 7.86 g of nitroglycerin when reacted with excess glycerol.

Answer:

Option B. 4.5g

Explanation:

The balanced equation for the reaction is given below:

2Na + 2H2O —> 2NaOH + H2

Next, we shall determine the mass of Na and the mass of H2O that reacted and the mass of H2 produced from the balanced equation. This is illustrated below:

Molar mass of Na = 23g/mol

Mass of Na from the balanced equation = 2 x 23 = 46g

Molar mass of H2O = (2.02x1) + 16 = 18.02g/mol

Mass of H2O from the balanced equation = 2 x 18.02 = 36.04g

Molar mass of H2 = 2.02 x 1 = 2.02g/mol.

Mass of H2 from the balanced equation = 1 x 2.02 = 2.02g

From the balanced equation above,

46g of Na reacted with 36.04g of H2O to produce 2.02g of H2.

Next, we shall determine the limiting reactant. This is illustrated below:

From the balanced equation above,

46g of Na reacted with 36.04g of H2O.

Therefore, 120g of Na will react with = (120 x 36.04)/46 = 94.02g of H2O.

From the calculations made above, we can see that it will take a high mass of H2O i.e 94.02g than what was given i.e 80g to react completely with 120g of Na. Therefore, H2O is the limiting reactant and Na is the excess reactant.

Finally, we shall determine the mass of H2 produced from the reaction as follow:

The limiting reactant will be used in this case as it will give the maximum yield of H2 since all of it is used up in the reaction.

From the balanced equation above, 36.04g of H2O reacted to produce 2.02g of H2.

Therefore, 80g of H2O will react to produce = (80 x 2.02)/36.04 = 4.5g of H2.

Therefore, 4.5g of H2 is produced from the reaction.

Explanation:

This is a fun question dealing with idea of Le Chatelier's principle.

In an exothermic reaction, you produce heat. This means that heat will act as a product (or be on the product side).

Suppose there's an imaginary equation:

A + B -----> C (Now if I lower the amount of B, the equilibrium will shift to left to make up the lost B, or to bring the system back to equilibrium)

Apply the same concept as above below:

A + B -------> C + Heat (as I mentioned, since this is exothermic reaction heat is written as product, so if you lower the temperature, which means basically lower the heat, the reaction will shift towards right to make up the lost heat, in this process you will make extra C which is products. Thus, your reaction makes more products.

Answers

Answer:

Increase in CO2 (g) over time.

No NaHCO3 (s) will be left after a time

Explanation:

The reaction, shown below;

2NaHCO3(s) → Na2CO3(s)+CO2(g)+H2O(ℓ) is a decomposition reaction. A decomposition reaction is a kind of chemical reaction in which a given chemical specie breaks up to give other chemical species. Decomposition may be induced by heat or light.

Usually, there is only one reactant in a decomposition reaction; the specie that disintegrates into the products. This reactant usually decreases in concentration steadily because it is converted into products. This is why the mass of NaHCO3(s) in the system continues to decrease steadily until it finally falls to zero.

Conversely, the concentration (for aqueous) or volume (for gases) or mass (for solid) products of the reaction increases steadily as the reaction progresses. This explains why the volume of CO2 in the system will steadily increase over time.

Explanation:

Step 1:

The balanced equation for the reaction. This is given below:

N2H4 + 7H2O2 → 2HNO3 + 8H2O

Step 2:

Determination of the mass of N2H4 that reacted and the mass HNO3 produced from the balanced equation. This is illustrated below:

Molar mass of N2H4 = (14x2) + (4x1) = 32g/mol

Mass of N2H4 from the balanced equation = 1 x 32 = 32g

Molar Mass of HNO3 = 1 + 14 + (16x3) = 63g/mol

Mass of HNO3 from the balanced equation = 2 x 63 = 126g

Summary:

From the balanced equation above,

32g of N2H4 reacted to produce 126g of HNO3.

Step 3:

Determination of the mass of N2H4 required to produce 120g of HNO3. This is illustrated below:

From the balanced equation above,

32g of N2H4 reacted to produce 126g of HNO3.

Therefore, Xg of N2H4 will react to produce 120g of HNO3 i.e

Xg of N2H4 = (32 x 120)/126

Xg of N2H4 = 30.48g

Therefore, 30.48g of N2H4 is required to produce 120g of HNO3.
