First, find the number of moles for each element. The molar
mass for nitrogen is 14 g/mol and that of hydrogen is 1 g/mol.
1.40 g N / 14 g/mol = 0.1 mol N
0.20 g H / 1 g/mol = 0.2 mol H
Find the mole ratio. Divide both numbers with the much lower
value. In this case, it is 0.1 mol N.
For N: 0.1 ÷ 0.1 = 1
For H: 0.2÷0.1 = 2
Thus, the empirical formula is 
.
Answer:

Explanation:
'an aerobic ' means it does not use oxygen
It is a <u><em>chemical compound</em></u> formed with a metal (mainly positive cations) with oxygen.
It is formed through the air as they react in the air together.
They are also BASES - ALKALINE (so neutralise acids)
Answer: B- Isotopes are often used for dating artifacts and fossils is incorrect.

Answer:
3L
Explanation:
The following data were obtained from the question:
V1 (original volume) = 6L
P1 (original pressure) = 1.5 atm
P2 (new pressure) = 2 x P1 ( since the new pressure is doubled)
P2 = 2 x 1.5
P2 = 3 atm
V2 (new volume) =?
Using the Boyle's law equation P1V1 = P2V2, the new volume can be obtain as follow:
P1V1 = P2V2
1.5 x 6 = 3 x V2
Divide both side by 3
V2 = (1.5 x 6)/3
V2 = 3L
From our calculations, the new volume will be half the original volume and this will be 3L
