Which statement is true for dipole-dipole forces? (4 points)

Group of answer choices

They are stronger than hydrogen bonding forces.

They are weaker than London dispersion forces.

They occur between ions and polar molecules.

They occur between polar molecules.

Answer:

The electrostatic attraction energy between ions of opposite charge is directly proportional to the charge on each ion (Q 1 and Q 2 in Equation 4.1. 1). Thus, more energy is released as the charge on the ions increases(assuming the internuclear distance does not increase substantially).

Decreasing the volume of the chamber by dragging the left side inward will increase the pressure of the container.

Pressure is the amount of force applied perpendicular to the surface of an object per unit area. The symbol for it is "p" or P.

If the volume of a container is decreased, the gas molecules have less space in which to move around. As a result, they will strike the walls of the container more often, and the pressure increases.

Answer:

The correct option is;

B. 5,000 years old

Explanation:

The percentage amount of carbon-14 in the sample = 50%

The half life of carbon 14 = 5700

The half-life of a substance is the time it takes for a given sample of the substance to decay such that only half of the original quantity of the substance remains

The half-life of carbon 14 is around 5.730 years, which means it takes 5,730 years for a given quantity of carbon 14 to decompose and have 50% of the original quantity remaining

Therefore, given that only 50% of carbon 14 is remaining in the bone, the duration for the decomposition is approximately the half life of carbon 14, and the best option is that the age of the bone is approximately 5,000 years.

Answer:

The quantity of heat : 226,000 J

Heat can be calculated using the formula:  

Q = mc∆T  

Q = heat, J  

m = mass, g  

c = specific heat, joules / g ° C  

∆T = temperature difference, ° C / K  

Q = m. Hf

Hf = heat of fusion

Heat required for vaporize /evaporated can be calculated from

Q = m . Hv

m = mass, g

Hv = the heat of vaporization, for water = 2,260 J/g

So :

[tex]\tt Q=100\times 2,260=226,000 J[/tex]

Answer:

In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. Mass cannot be created or destroyed in a chemical reaction.

Answer:

Hola

Explanation:

The net charge of an ion that has 11 protons, 10 electrons, and 12 neutrons is +1. Thus option A is correct.

Net charge is defined as when the number of electrons in an atom does not equal the number of protons, the atom is said to be unstable.
If the number of electrons are less than the number of protons, then they will have positive net charge.

If the number of electrons are more than the number of protons, then they will form negative net charge.

Electrons are defined as negatively charged subatomic particle which together with protons and neutrons forms atom.

Thus, the net charge of an ion that has 11 protons, 10 electrons, and 12 neutrons is +1. Thus option A is correct.

Explanation:

Sodium metal reacts rapidly with water to form a colourless basic solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The reaction continues even when the solution becomes basic. The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.

8 hcl and h2 is reactants.

Answer:

single or double covalent bonds

Explanation:

Answer:

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

where

P1 is the initial pressure

P2 is the final pressure

V1 is the initial volume

V2 is the final volume

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

So we have

[tex]P_2 = \frac{95 \times 34}{55} = \frac{3230}{55} \\ = 58.72727272...[/tex]

Density = Mass/Volume

Explanation:

For the example the answers are Copper and Iron

In the case of chromium having a density of 7.2, anything greater than 7.2 is a higher density. 18/2=9 and 16/2=8. The copper and iron metals were the only ones that had a higher output than the density of chromium.

Answer:

See explanation

Explanation:

From the statement of the first law of thermodynamics, energy is neither created nor destroyed, but is transformed from one form to another.

Thermal energy is possessed by the hot air while the fire is burning. This  thermal energy was obtained from the chemical energy stored in carbohydrates(cellulose) that is present in wood material. As the combustion proceeds, chemical energy stored in chemical bonds of the wood material converts into thermal energy (heat energy). The chemical reaction involved in the combustion of wood can be simplified as shown below; n represents the number of glucose units that combine to make up the cellulose present in the wood material.

nC6H12O6(s) + 6nO2(g) ===> 6nCO2(g) + 6nH2O(g)

n may even be as much as thousands of glucose units.

Explanation:

Chemical equation:

2Al + 6HCl     →     2AlCl₃ + 3H₂

In given balance chemical equation there are 3 moles of hydrogen are formed.

Mass of hydrogen in gram:

Formula:

Number of moles = mass/molar mass

Mass = number of moles × molar mass

Molar mass of hydrogen = 1.008×2 = 2.016 g/mol

Mass = 2.016 g/mol× 3 mol

Mass = 6.05 g

It is almost equal to 6.06 g thus option B is correct.
