I believe cc would result in a recessive pair.
Answer is: a.2h2(g) + o2(g) 2h2o(g) + 483.6 kj.
Conservation of mass (mass is never lost or gained in chemical reactions), during chemical reaction no particles are created or destroyed, the atoms are rearranged from the reactants to the products.
The law of conservation of energy states that the total energy of an isolated system remains constant; energy can neither be created nor destroyed; it can only be transformed or transferred from one form to another.
Balanced chemical reaction: 2H₂ + O₂ → 2H₂O ΔH = 483.6 kJ.
There are four hydrogen atoms and two oxygen atoms on both side of balanced chemical reaction.
Answer: the density of the object / the mass it takes to stand up.
Explanation:
