Question

Question 2:
Ali) What is a chemical reaction? Give an example
ii) What is a chemical equation. Give an example​

Answer 1

Answer:

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. combustion. Log burning in a fire. Burning wood is an example of a chemical reaction in which wood in the presence of heat and oxygen is transformed into carbon dioxide, water vapour, and ash.N

Given that n stands for “any number,” the general formula of this class is therefore CnH2n + 2. ... For example, the molecular formulas C2H4 and C3H6 for ethylene and propylene, respectively, state the number and kind of every atom present in a molecule of each substance.

Answer 2

Answer:

2 )   i)  A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products. Log burning in a fire. Burning wood is an example of a chemical reaction in which wood in the presence of heat and oxygen is transformed into carbon dioxide, water vapour, and ash

ii) Reactants are converted to products, and the process is symbolized by a chemical equation. For example, iron (Fe) and sulfur (S) combine to form iron sulfide (FeS). Fe(s) + S(s) → FeS(s) The plus sign indicates that iron reacts with sulfur.
