Answer:

Balancing of equation involves making sure the number of atoms of an element on the left hand side(reactant) is equal to the number of atoms of an element on the right hand side(product)

4NH3 + 14O2 → 4NO2 + 6H2O

In the equation above,the number of Oxygen on the left is (14*2)=28 while the number of oxygen on the right is (4*2+6)=14. This makes it an unbalanced equation.

Sort the resources into the correct categories.
Lapatulllka [165]

Answer:

Renewable Resources: are considered unlimited, are replaced faster than used.

Nonrenewable Resources: are used more quickly than replaced, have fixed amounts, cannot be replaced in a short time.

Explanation:

Renewable resources are natural resources that are able to naturally regenerate themselves, hence, they are considered to be unlimited. They are usually replaced faster than they are used because they have a short regeneration time. A good example is the solar energy.

Nonrenewable resources are those natural resources that cannot naturally regenerate and when they do, it takes a very long time (usually millions of years). They are therefore used at a much faster rate than they are being replaced and their natural deposits are more or less fixed due to the long regeneration time. A good example is the crude oil deposit.

Hence:

Renewable Resources: are considered unlimited, are replaced faster than used.

Nonrenewable Resources: are used more quickly than replaced, have fixed amounts, cannot be replaced in a short time.
