Question

balance following equations in trial and error method
1. magnesium reacts with hydrochloric acid to give magnesium chloride
2.barium chloride reacts with potassium sulphate to form barium sulphate
3. respiration reaction
4.zinc reacts with silver nitrate to give silver and zinc nitrate
5.sodium hydroxide reacts with sulphuric acid​

Answer 1

this is the answer of first one and the the product there will be magnesium chloride + hydrogen

Answer 2

1. Mg + HCl → MgCl

$\underline\red{Balanced~equation}$ :-

Mg + Cl → ${MgCl}_{2}$ + ${H}_{2}$

$<font color=blue>$

2. ${BaCl}_{2}$ + ${K}_{2}{SO}_{4}$ → ${BaSO}_{4}$

$\underline\red{Balanced~equation}$ :-

${BaCl}_{2}$ + ${K}_{2}$ → ${BaSO}_{4}$ + ${2K}_{2}{KCl}$

3. ${C}_{6}{H}_{12}{O}_{6}$ + ${6O}_{2}$ → ${6CO}_{2}$ + ${6H}_{2}{O}$ + ATP

4. ${Zn}$ + ${AgNO}_{3}$ → ${Ag}$ + ${Z}$${({NO}_{3})}_{2}$

5. ${NaOH}$ + ${H}_{2}{SO}_{4}$ → ${Na}_{2}{SO}_{4}$ + ${H}_{2}{O}$

$\underline\green{Balanced~equation}$ :-

${2NaOH}$ + ${H}_{2}{SO}_{4}$ → ${Na}_{2}{SO}_{4}$ + ${H}_{2}{O}$
