Write a balanced equation for the reaction of sulfuric acid (H,SO) and

Sonbull [250]

Answer:

Explanation:

Word equation:

sulfuric acid + ammonium hydroxide → ammonium sulfate + water

Chemical equation:

H₂SO₄ + NH₄OH → (NH₄)₂SO₄ + H₂O

Balanced chemical equation:

H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + 2H₂O

The given reaction is the reaction of acid with base. When acid and base react salt and water are produced. In given reaction an acid sulfuric acid and base ammonium hydroxide react and form ammonium sulfate salt and water. The given reaction also follow the law of conservation of mass.

Steps to balance the equation:

Steps 1;

H₂SO₄ + NH₄OH → (NH₄)₂SO₄ + H₂O

H = 7 H = 10

S = 1 S = 1

O = 5 O = 5

N = 1 N = 2

Step 2:

H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + H₂O

H = 12 H = 10

S = 1 S = 1

O = 6 O = 5

N = 2 N = 2

Step 3:

H₂SO₄ + 2NH₄OH → (NH₄)₂SO₄ + 2H₂O

H = 12 H = 12

S = 1 S = 1

O = 6 O = 6

N = 2 N = 2

4. Ammonia is produced by the chemical reaction of nitrogen and hydrogen. N2 (g) + 3H2(g) →→ 2NH3 (9) (A) Calculate the number o

Makovka662 [10]

Answer:

a) No. of moles of hydrogen needed = 5.4 mol

b) Grams of ammonia produced = 27.2 g

Explanation:

$N_2 (g) + 3H_2(g) \rightarrow 2NH_3 (g)$

No. of moles of nitrogen = 1.80 mol

1 mole of nitrogen reacts with 3 moles of hydrogen

1.80 moles of nitrogen will react with

= 1.80 × 3 = 5.4 moles of hydrogen

No. of moles of hydrogen = 2.4 mol

It is given that nitrogen is present in sufficient amount.

3 moles of hydrogen produce 2 moles of $NH_3$

2.4 moles of hydrogen will produce

= $\frac{2}{3} \times 2.4 = 1.6\ mol\ of\ NH_3$

Molar mass of ammonia = 17 g/mol

Mass in gram = No. of moles × Molar mass

Mass of ammonia in g = 1.6 × 17

= 27.2 g
