A metal Y forms two different chloride if 12.7g chloride A and 16.3g of chloride B contains 7.1g and 10.7g of chloride respectively, show that the figure agree with the law of multiple proportion. write their formulae

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.

the answer is 0.8m.

i hope this !

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
