Answer:

The correct option is;

Sulfur oxides - acid precipitation

Explanation:

Here we have sulfur oxide when present in the atmosphere and mixed with oxygen water and other chemicals form acidic precipitation known as acid rain.

The sulfur oxides reacts with water in the clouds to form sulfuric acid as follows;

The sulfur gas is first oxidized

SO₂ + OH → HOSO₂

The next stage is the formation of sulfur trioxide

HOSO₂ + O₂ → HO₂ + SO₃

Sulfur trioxide combines with water to form sulfuric acid

SO₃ + H₂O → H₂SO₄ (aq).

A poisoned pill contains 0.00048 moles of KCN. How many molecules are in this sample?
mario62 [17]

Answer:

2.89 \times  {10}^{20}  \:  \: molecules

Explanation:

The number of molecules of KCN can be found by using the formula

<h3>N = n × L</h3>

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 0.00048 × 6.02 × 10²³

We have the final answer as

2.89 \times  {10}^{20}  \:  \:  \: molecules

Hope this helps you
