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.
Condensation polymerization : releasing water as by product, occurs in monomer that has functional group that can react with each other e.g alcohol&carboxlic acid to form polyesters, carboxylic acid and amines to form polyamides,etc.
Radical Polymerization: occurs by propagating radical monomers or monomer that has unsaturated bonds, such as ethene, initiated by formation of radical from the monomer by using uv lights/other initiator, does not produce any by products

Explanation:
The advantages of using natural gas rather than coal are the following,
- Natural gas is present in large amount than coal.
- Natural gas is less costly than other fossil fuel sources of energy.
- It increases security by decreasing dependence.
- Natural gas is more environmentally friendly.
- Natural gas is much safer to store.
- It is reliable.
- Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil.
- Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas-power plant compared with emissions from a typical new coal plant.
Explanation:
magnesium can be used for the construction as only when the metal is divided into fine pieces or as a thin sheet, magnesium will burn rapidy.
