<u>Charge:</u>
An electron has a negative charge and a <em>n</em>eutron has a <em>n</em>eutral charge.
<u>Size:</u>
Electrons have a really small mass whereas the neutron has a mass of about 1 amu.
<u>Location:</u>
Neutrons are found in center of an atom, but electrons are around it.
<u>Number:</u>
The number of electrons and neutrons in atom varies.
the balanced equation for the formation of ammonia is
N₂ + 3H₂ ---> 2NH₃
molar ratio of N₂ to NH₃ is 1:2
mass of N₂ reacted is 8.0 g
therefore number of N₂ moles reacted is - 8.0 g / 28 g/mol = 0.286 mol
according to the molar ratio,
1 mol of N₂ will react to give 2 mol of NH₃, assuming nitrogen is the limiting reactant
therefore 0.286 mol of N₂ should give - 2 x 0.286 mol = 0.572 mol of NH₃
therefore mass of NH₃ formed is - 0.572 mol x 17 g/mol = 9.72 g
a mass of 9.72 mol of NH₃ is formed
Answer:
It's true :) Hope that helps
Answer:
Because Oxygen shares 2 electrons with mutual bond interaction forming covalent bond . thus it is diatomic due to K shell 2 electrons mutual sharing .
Explanation:
I think the answer is <span>B. The sun's gravitational pull on Planet A is equal to its gravitational pull on Planet B because distance does not affect gravity.
