Question

With the aid of a balanced chemical equation explain Chemical Reactions and the Types Of Chemical Reaction

Answer 1

A chemical reaction is a process in which atoms are rearranged to form new molecules or substances. During a chemical reaction, chemical bonds are broken and formed, resulting in the transformation of reactant molecules into product molecules. The reactants and products of a chemical reaction are characterized by their chemical formulas, which describe the types and numbers of atoms present in the molecules.

A balanced chemical equation is a written representation of a chemical reaction that shows the reactants on the left side of the equation and the products on the right side. The equation is balanced by adjusting the coefficients (the numbers in front of the chemical formulas) so that the number of atoms of each element is the same on both sides of the equation. This ensures that the law of conservation of mass is obeyed, which states that matter cannot be created or destroyed during a chemical reaction.

There are several types of chemical reactions, including:

Decomposition reactions: These reactions involve the breakdown of a single compound into two or simpler substances. An example of a decomposition reaction is the thermal decomposition of water to form hydrogen and oxygen gases:

2H2O (l) -> 2H2 (g) + O2 (g)

Displacement reactions: These reactions involve the replacement of one element with another element in a compound. An example of a displacement reaction is the reaction of zinc with hydrochloric acid to form zinc chloride and hydrogen gas:

Zn (s) + 2HCl (aq) -> ZnCl2 (aq) + H2 (g)

Redox reactions: These reactions involve a transfer of electrons from one species to another. An example of a redox reaction is the reaction of magnesium with oxygen to form magnesium oxide:

2Mg (s) + O2 (g) -> 2MgO (s)

Combination reactions: These reactions involve the combination of two or more substances to form a single compound. An example of a combination reaction is the reaction of hydrogen and oxygen to form water:

2H2 (g) + O2 (g) -> 2H2O (l)

Acid-base reactions: These reactions involve the transfer of a proton from an acid to a base. An example of an acid-base reaction is the neutralization of hydrochloric acid with sodium hydroxide to form water and sodium chloride:

HCl (aq) + NaOH (aq) -> H2O (l) + NaCl (aq)

Answer 2

Answers

1.)reactants: nitrogen and hydrogen; product: ammonia.

2.)reactants: magnesium hydroxide and nitric acid; products: magnesium nitrate and water.

3.)N 2 + 3H 2 → 2NH 3

4.)Mg(OH) 2 + 2HNO 3 → Mg(NO 3) 2 + 2H 2O.

5.)2NaClO 3 → 2NaCl + 3O 2

6.)4Al + 3O 2 → 2Al 2O 3

7.)N 2(g) + 3H 2(g) → 2NH 3(g)
