Question

Write the balance chemical equations for the following in
1. Hydrogen combines with oxygen to form water

2. Nitrogen reacts with hydrogen to produce ammonia

3. Sodium bicarbonate decomposed into sodium carbonate, water and carbon dioxide.

4. Aluminium combines with oxygen to give aluminium oxide

5. Magnesium reacts with hydrochloric acid to form magnesium chloride and hydrogen.​

Answer 1

Answer:

1)2H2(g) + O2(g) → 2H2O(l )

2)N2+3H→2NH3.

3)sodium carbonate (Na2CO3), water (H2O) and carbon dioxide (CO2)

4)4 moles of Al reacts with 3 moles of O2 to get 2 Moles of aluminium oxide. 0.5 moles of Al reacts with 0.5x 3/4 = 0.375 moles of oxygen.

5)Mg(s) + 2 HCl(aq) --> MgCl 2(aq) + H 2(g)

Answer 2

Explanation:

$\huge\mathfrak\green{Answer \:no. \:1}$

2H2+O2→2H2O

$\huge\mathfrak\green{Answer \:no. \:2}$

N2+3H→2NH3

$\huge\mathfrak\green{Answer \:no. \:3}$

2NaHCO3 → Na2Co3 + CO2 + H2O

$\huge\mathfrak\green{Answer \:no. \:4}$

4Al + 3O2 → 2Al2O3

$\huge\mathfrak\green{Answer \:no. \:5}$

Mg + 2 HCl → MgCl2 + H 2
