Answer:
the answer is the first one (a)
According to the equation, the ratio of the reactant Cu and product CuO is 2:2, thus 1:1. Therefore to produce 2.44 mol CuO, 2.44 mol Cu is required. The molecular weight of Cu is 64. So the mass of Cu that is required to produce 2.44mol CuO is 2.44mol * 64 g/mol = 156.16 g.
A difference between plant cells and animal cells is that most animal cells are found whereas most plant cells are rectangular. Plant cells have rigid cell wall that surrounds the cell membrane.animals do not have a cell wall
