You performed this reaction: 2Cu + S --> Cu2S You used 80.0g Cu and 25.0g S.

What is the theoretical yield of Cu2S?

Which reactant is limiting?

a
The theoretical yield is 124.1g Cu2S and the limiting reactant is Cu

b
The theoretical yield is 100.2g Cu2S and the limiting reactant is S

c
The theoretical yield is 124.1g Cu2S and the limiting reactant is S

d
The theoretical yield is 100.2g Cu2S and the limiting reactant is Cu

also don't post unneccessary stuff to get points I need a real answers asap pls

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
