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
Answer:
Sugar, sodium chloride, and hydrophilic proteins
Answer:
its letter d ..................................
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
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.
