Silver sulfide and hydrogen gas are combined to form silver and hydrogen sulfide. 3.0 g of H2 and 100 g of Ag2S are used to produce only 85 g of Ag. a) Write the balanced chemical equation for this reaction.

b) What is the actual yield?

c) Which substance is in excess?

d) What quantity is in excess?

Percent ionization for a weak acid (ha) is determined by the following formula: percent ionization=[ha] ionized[ha] initial×100%for strong acids, ionization is nearly complete (100%) at most concentrations. however, for weak acids, the percent ionization changes significantly with concentration. the more diluted the acid is, the greater percent ionization. a certain weak acid, ha, has a ka value of 9.4×10? 7.part acalculate the percent ionization of ha in a 0.10 m solution. part bcalculate the percent ionization of ha in a 0.010 m solution
