The amount of calories you weight
Assuming that 2H2O(l) is the product, the reactants would be 2H2(g) and O2(g). The number of moles in the reactants would be 2 moles of H2 and 1 mole of O2.
Answer:
its absorbed by heat from consumers
The reaction equation given is already balanced. So the ratio of the reactants and products is the same as the ratio of coefficients. Then the answer is 4 moles.
Answer:
Closely packed cations with loosely held valence electrons
Explanation:
Pure metals contain so-called metallic bonds. These metallic bonds are often referred to as sea of electrons. Metals consist of closely packed cations (and, hence, that's why they have a high density) with loosely held valence electrons (this is the reason why metals tend to lose their electrons rather than gain, besides, it's also the reason why the first ionization energy for the metals is relatively low).
