It’s b for sure that’s the answer
In chemical reactions, the actual yield is not the same as the expected yield . Actual yield is lower than the theoretical yield . Then we have to find the yield percentage. To see what percentage of the theoretical yield is the actual yield.
Percent yield = actual yield / theoretical yield x 100%
Percent yield = 24.6/55.9 x100%
Percent yield = 44%
I think it's A, <span>an action which causes movement and an opposite reaction</span>
Tarnish is Ag2S-silver sulfide and the oxidation state of silver is +1
