Answer 1

Answer:

Endothermic reaction:

N2(g) + O2(g) + Heat -> 2NO(g)

Nitrogen Oxygen Nitrogen

monoxide

Exothermic reaction:

C(s) + O2(g) -> CO2(g) + Heat

Carbon Oxygen Carbon dioxide

Neutralisation reaction:

NaOH + HCl -> H2O + NaCl

Redox reaction(combination of Oxidation and reduction reaction):

CuO + H2 -> Cu + H2O

Copper Hydrogen Copper Water

oxide

Precipitation reaction:

BaCl2(aq)+CuSO4(aq) -> BaSO4(s)+ CuCl2(aq)

Barium Copper Barium Copper

chloride sulphate sulphate chloride

Answer 2

Answer:

Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.Nov 4, 2020
