Answers

Answer 1

Answer:

Be,Mg,Ra etc

Explanation:

It should be palced in group 2A because as it reacts with chlorine in ratio of 1:2 . It's valancy is 2 and is metal as it react with non metal donating two electrons .

one more thing it fits there orderly

What is the molarity of 2 moles of a compound dissolved in 4 L of water?
A. 2 M
B. 0.5 M
C. 4M
D. 1 M

Answers

Answer:

[tex]\boxed {\boxed {\sf B. \ 0.5 \ M}}[/tex]

Explanation:

Molarity is a measure of concentration in moles per liter. The formula for calculating molarity is:

[tex]molarity= \frac{moles \ of \ solute}{ liters \ of \ solution}[/tex]

There are 2 moles of a compound or the solute. There are 4 liters of water or the solution.

moles of solute= 2 mol liters of solution = 4 L

Substitute the values into the formula.

[tex]molarity = \frac{ 2 \ mol}{ 4 \ L}[/tex]

Divide.

[tex]molarity= 0.5 \ mol /L[/tex]

1 mole per liter is equal to 1 Molar, so the solution's molarity of 0.5 mol/L is equal to 0.5 M.

[tex]molarity = 0.5 \ M[/tex]

The molarity of the solution is 0.5 Molar and choice B is correct.

Hope this helps

Oxygen gas O2 is a compound, a molecule and a pure substance.

Oxygen gas is a compound because it contains more than one atom( two oxygen atoms) that are chemically combined together.

Oxygen gas is a molecule because it can exist independently as a unit and the oxygen atoms are covalently bound.

It is a pure substance because it contains only oxygen molecules.

Karma is saying to add water to acid.By which acid will be diluted and become less hazardous.Sonam is saying to add an indicator .She is advising wrong .Indicator won't absorb much acid.For which this is uneffective unless it changes a colour.Sangay's idea is also fluff.Salt won't react with acid to neutralise. Because both contains halogens.Like Sodium chloride is a salt and Hydrochloric acid is also a salt.Yes,Tshering's idea is quite good.by this acid will be neutralized some.Thsomo's idea is also good .Its better to call teacher but we should solve it by ourselves.I think karma's suggestion is best .It is better to dilute the acid .But we should add water while mixing acid with spoon .

It id desired to increase thr volume of gas by 20% without changing the pressure .To what temperature the gas must be heated if the initial temperature of the gas is 27degree celcius?​

Answers

Answer:

32.4°C

Explanation:

Consider the following expression:

P•V/T =P'•V'/T'

Where P and P' are respectively the initial and the final pressure, V and V's are respectively initial and final volume, and T and T' are respectively initial and final temperature.

We know that the pressure cannot change, so it means that P = P'

We also know that the volume must be increased in 20%, and if we multiply the volume by 1.2 is like increase it in 20%, so we can write that V' = 1.2•V, and changing a little more we can write that V'/V = 1.2

So let's do some maths:

P•V/T = P'•V'/T'

T'•P•V/T = P'•V'

T'•P•V = P'•V'•T

T'=P'•V'•T/P•V

We know that P'=P so the division is equal to 1:

T'= 1•V'•T/V

We also know that V'/V = 1.2, so:

T' = 1.2•T

And we know the value of T, it's 27, so now we just have to solve it:

T' = 1.2•27

T' = 32.4°C
