If we had 11.3 g of nitrogen and 2 g of hydrogen, how much nitrogen would remain if all the hydrogen was consumed? g
meriva
Hydrogen reacts with nitrogen to produce ammonia based on the following equation:

3H2 + N2 ........> 2NH3

This means that each 6 grams of hydrogen react with 28 grams of nitrogen. To know how many grams of nitrogen are required to react with 2 grams of hydrogen, we will simply do cross multiplication as follows:

mass of nitrogen = (2 x 28) / 6 = 9.334 grams

Therefore, if we have 11.3 grams of nitrogen, 9.334 grams would react with 2 grams of hydrogen.

remaining mass of nitrogen = 11.3 - 9.334 = 1.966 grams

A gas occupies a volume of 0.2l at 25 kpa. What volume will the gas occupy at 2.5kpa
EleoNora [17]

Boyle's Law: P₁V₁ = P₂V₂

So (25 kpa)(0.21) = (2.5 kpa) V₂

(25 kpa × 0.21)/ 2.5 kpa = 2.1

2.1 = V₂

Why is the radius of a positive ion always less than the radius of its neutral atom? (A) the nucleus pulls the remaining electro
Rina8888 [55]
Positive ions are positive because they have lost electrons.
(A)-This sounds accurate, but is actually not true. When an atom loses an electron and forms a positive ion, there will be less negative charge from the electrons to attract the positively charged nucleus. Losing electrons will actually decrease the attraction between the electrons and the nucleus.
(B)-This is true in some cases, but not all. If, for example, sodium were to lose an electron, it would drop down to having its largest orbital being in the second energy level, and would decrease in size. If magnesium were to lose an electron, it would still have one electron in the third energy level, so it wouldn't drop down an energy level.
(C) and (D)-Not sure where these answers even came from.

The actual reason behind the radius of a positive ion being smaller than the radius of its neutral atom is that the repulsive force between the electrons themselves is decreased, causing them to move closer together.
