Answer:

A = 1.6

B = 3

Explanation:

When you are dividing exponents, you subtract them:

10^12 / 10^9 = 12 - 9 = 3

10³ would be the exponent

5.6/3.5 = 1.6

So, 1.6(10³) would be your answer.

Nitrogen gas has the chemical formula N_{2}, which means that two atoms of nitrogen element combined to form nitrogen gas.

The combination of two atoms of element nitrogen produce dinitrogen atom.

Dinitrogen is the nitrogen gas usually present in atmosphere of the earth in abundance.

2 atoms of nitrogen element

N + N = N_{2}

the gas is colorless and odorless formed at standard condition of temperature and pressure. The two nitrogen atoms are tightly bonded with triple bonds in between the atoms.
