When 0.2006 g of oxalic acid (C2O4H2) is burnt in the calorimeter whose heat capacity is 1.238 kJ/K. the temperature increased by 0.4577 K. Calculate the heat of combustion of oxalic acid in kJ per mole.

it means there are 3 atoms of oxygen

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "
