Question

analytical chemistry studies what specifically? *
isolating and understanding chemical composition and its uses
living things
physics principles to explain chemical reactions
non - caron based compounds
determine the products of the following reaction *
combustion chemical reaction

Explanation:

Analytical chemistry focuses on isolating and understanding chemical composition and its uses. The study of living things is biology, using physics principles to explain chemical reactions is physical - chemistry, and non - carbon based compounds are studied in inorganic chemistry. For the reaction of methane ($CH_4$) with oxygen ($O_2$), it is a combustion reaction and the products are carbon dioxide ($CO_2$) and water ($H_2O$) as shown.

Answer:

1. Isolating and understanding chemical composition and its uses
2. The products are $CO_2$ and $2H_2O$
