in any chemical process, matter is neither lost nor gained.

the changing of substances to other substances by the breaking of bonds in reactants and the formation of bonds in products.

these are the elements or compounds that enter into a chemical reaction.

this is the substance(s) formed in a chemical reaction.

1.5 g of h2 added to 12 g of o2 produces

1 g of h2 added to 35.5 g of cl2 produces

a) 36.5 g of HCl is formed by 1 g of H2 added to 35.5 g of Cl2

b) 13.5 g of H2O is formed by adding 1.5 g of H2 to 12 g of O2

c) A chemical reaction is when the changing of substances to other substances by breaking of bonds in reactants and the formation of bonds in products.

d) The law of Conservation of Matter states that in any chemical process, matter is neither lost nor gained.

e) The products are the substances formed in a chemical reaction.

f) Reactants are the elements of compounds that enter into a chemical reaction.

Explanation:

In a chemical reaction, the atoms of an element or compound are rearrange, that is the reason why you have different products at the end (what is it called products) that you had at the begging (what is called reactants). Also does no matter the kind of chemical reaction, the matter in universe stay the same but in a different expression.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
