Liquid water in the earth's air is an example of a solution. what type of solution would this be?

1 answer:

6 0

Solutions are homogeneous mixtures made up of two non-reacting compounds. The component which is present in large quantity is called as solvent and the component in small quantity is called as solute There are six types of solutions.

1. Gas (solvent) - Gas (solute) Example= Air

2. Liquid (solvent) - Gas (solute) Example= Fizzy Drinks

3. Liquid (solvent) - Liquid (solute) Example= 96% Ethanol in Water

4. Liquid (solvent) - Solid (solute) Example= Sugar in Tea

5. Solid (solvent) - Solid (solute) Example= Brass, 18 caret Gold

6. Solid (solvent) - Gas (solute) Example= Marshmellow

Result:
In equation earth air is solvent (as it is in large quantity) and water vapors (gas) which are in small quantity is solute.
So, it is Gas - Gas Solution.

Consider the generic reaction: 2 A(g) + B(g) → 2 C(g). If a flask initially contains 1.0 atm of A and 1.0 atm of B, what is the

irina1246 [14]

Answer:

b. 1.5 atm.

Explanation:

Hello!

In this case, since the undergoing chemical reaction suggests that two moles of A react with one moles of B to produce two moles of C, for the final pressure we can write:

$P=P_A+P_B+P_C$

Now, if we introduce the stoichiometry, and the change in the pressure $x$ we can write:

$P=1.0-2x+1.0-x+2x$

Nevertheless, since the reaction goes to completion, all A is consumed and there is a leftover of B, and that consumed A is:

$x=\frac{1.0atm}{2}=0.5atm$

Thus, the final pressure is:

$P=1.0-2(0.5)+1.0-(0.5)+2(0.5)\\\\P=1.5atm$

Therefore the answer is b. 1.5 atm.

Best regards!
