The number of oxygen atoms that are in 4 Al₂O₃ are 12 atoms

<u><em> Explanation</em></u>

The subscript in a chemical formula indicate the number of atoms of element immediately before the subscript.

coefficient is the number in front of the formula and tells us how many molecules of a given formula are present.

Since 4Al₂O₃ has coefficient of 4 and the subscript of O is 3 the number of O atoms = 4 x 3=12 atoms

Where does acid rain occur?

vlabodo [156]

<span>Acid rain is precipitation that contains high levels of nitric or sulfuric acid. Natural and industrial sources can release sulfur dioxide and nitrogen oxide into the atmosphere, leading them to combine chemically with oxygen and water to form their respective acidic molecules. These acids are then deposited through rain or dust depending on the climate of the region. While acid rain can occur anywhere in the world, it is prevalent in regions that have high industrial activity.</span>

Which one of the following reactions IS NOT balanced? 1. 2 KNO3 + 10 K → 5 K2O + N2 2. 2 SO2 + O2 → 2 SO3 3. SF4 + 3 H2O → H2SO3

Delicious77 [7]

Answer:

2 KNO₃ + 10 K → 5 K₂O + N₂ (option 1)

Explanation:

1. 2 KNO₃ + 10 K → 5 K₂O + N₂

We have in reactant side:

2 K, 2N, 6O and 10 K. In conclussion, 12 K, 2N and 6 O

We have in product side.

10 K, 5O and 2 N

This equation is unbalanced

2. 2 SO₂ + O₂ → 2 SO₃

In reactant side we have 2 S and 6 O

In product side we have 2 S and 6 O

3. SF₄ + 3 H₂O → H₂SO₃ + 4 HF

In reactant side we have 1 S, 4F, 6 H and 3 O

In product side we have 1 S, 4F, 6 H and 3 O
