bonufazy [111]
1) Reaction:

Mg(s) + 2HCl (aq) ----> H2(g) + MgCl2(aq)

2) Analysis

An increase in pressure affects directly the rate of reaction involving reactiong gases. Changing the pressure where there are only solids or liquids does not affect the rate of reaction.

This reaction is not an equilibrium, the reaction is only forward. So, the reacting components, Mg(s) and HCl(aq) are a solid and a liquid.

Therefore, the reaction is not affected by the change in pressure.

Answer: the reaction is not affected at all.

For an aqueous solution of sucrose (C12H22O11), determine: (a) the molarity of 3.30 L of a solution that contains 225.0 g of suc
dusya [7]

Answer:

a) Molarity = 0.199M

b) 21.6L of solution

c) 0.199 moles of sucrose in 1L

Explanation:

a) Molarity is the ratio of moles of solute (sucrose) in volume of solution (3.30L):

<em>Moles sucrose -Molar mass: 342,3g/mol-:</em>

225.0g * (1mol / 342,2965g) = 0.6573 moles

Molarity = 0.6573 moles / 3.30L

<h3>Molarity = 0.199M</h3><h3 />

b) 0.199M means 0.199 moles in 1L. 4.30 moles are in:

4.30 mol * (1L / 0.199mol) = 21.6L of solution

c) By definition, there are 0.199 moles of sucrose in 1L. This is the meaning of 0.199M
