When solutions containing silver ions and chloride ions are mixed, silver chloride precipitates: ag+(aq)+cl−(aq)→agcl(s)δh=−65.5kj. calculate δh for formation of 0.490mol of agcl by this reaction.

The ΔH for the formation of 0.490 mol of AgCl is - 32.095 kJ.

Explanation:

Ag⁺(aq)+Cl⁻(aq)→ AgCl(s) ΔH=−65.5kJ

We need to consider that the value of ΔH given is for each mol of AgCl formed.

1 mol AgCl - 65.5 kJ

0.490 mol AgCl      x

x = - 32.095 kJ

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
