The volume of 1.0 g of nitrogen in a balloon is increased. It causes: the mass of the gas to decrease the density of the gas to increase and the pressure of the gas to decrease the temperature of the gas decrease.
<h3>What is volume?</h3>
How much space an object or substance takes up.
If you increase the temperature of the gas in the balloon, the pressure will initially increase. The balloon will expand until the pressure inside drops back down and is equal to the pressure outside.
If you increase the atmospheric pressure, the balloon will compress until the pressure inside equals the new pressure outside.
If you remove gas from the balloon, the pressure will drop, causing the balloon to compress until the pressure is again equal to the pressure outside.
if you place the balloon underwater, it will be under greater pressure, causing the balloon to compress until the inside pressure equals the new outside pressure.

The words that complete the blanks are hypothesis and experimentation.
<h3>What is scientific knowledge?</h3>
The process by which scientists obtain information and establish knowledge is;
Observation ---> hypothesis ------> experiments ------> Theory -------> Law.
Thus after the process of observation what we have is merely a scientific hypothesis that needs to pass through the process of rigorous experimentation before it is proven to be true.
Thus the words that complete the blanks are hypothesis and experimentation.

Nitrogen in this compound has 2 atoms. 2 multiplied by its mass, 14.007, equals 28.014. Divide 28.014 by the molar mass of calcium nitrate: 28.014/164 = 0.17081. Multiply this by 100 to achieve its percentage: 0.17081 x 100 = 17.08%
<span>Inorganic Topaz is a silicate mineral of aluminium and fluorine. With the chemical formula Al2SiO4(F,OH)2.</span>
a) Number of protons = number of electron in the atom = atomic number
So it has 7 protons answer
N-3 has gained 3 electron so number of electrons + 7+3
= 10 answer
