Please help!! What is the theoretical yield of hydrogen gas if 36.0 g of water undergoes electrolysis to produce molecular hydrogen and molecular oxygen and 38.0g of hydrogen is collected?

219 grams of iron (iii) oxide reacts with excess carbon according to the reaction equation shown below. fe2o3 + c → fe + co2 after a scientist performs the chemical reaction they find the actual yield of iron to be 57.4 grams. calculate the percent yield of this chemical reaction.

If a substance is not at its melting or boiling point, as the heat content of a sample of matter increases, its temperature increases the number of intermolecular bonds decreases the space between particles increases the particles move faster

The clouds are grey and ground is wet. a quantitative b qualitative
