Answer:
Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2(
Answer:
7.5 mol of hydrogen would be needed to consume the available nitrogen.
Explanation:
- The balanced equation of the reaction of hydrogen with nitrogen is:
<em>3H₂ + N₂ → 2NH₃</em>
it is clear that 3mol of hydrogen react with 1 mol of Nitrogen to give 2 mol of ammonia.
- firstly, we need to calculate the number of moles of both
for H₂:
number of moles = mass / molar mass = (7.00 g) / (2.00 g/mol) = 3.5 mol.
for N₂:
number of moles = mass / molar mass = (70.00 g) / (28.00 g/mol) = 2.5 mol.
<u>using cross multiplication</u>
1 mol of N₂ needs → 3 mol of H₂
2.5 mol of N₂ needs → ??? mol of H₂
∴ the number of mol of H₂ needed = (3*2.5) / 1 = 7.5 mol
So, the right choice is:
7.5 mol of hydrogen would be needed to consume the available nitrogen.
