<u>Answer:</u>
3.67 moles
<u>Step-by-step explanation:</u>
We need to find out the number of 
moles present in 350 grams of a compound.
Molar mass of 
= 24.305
Molar mass of 
= 35.453
So, one mole of = 24.305 + (35.453 * 2) = 95.211g
1 Mole in 1 molecule of = 
Therefore, number of moles in 350 grams of compound = 0.0105 * 350
= 3.67 moles
In the first shell there is 2 electrons and on the second shell there is 4 elections.
Answer:
Explanation:
The equation of the reaction:
Nitrogen gas N₂ reacts with Hydrogen as H₂ to produce ammonia NH₃;
N₂ + H₂ → NH₃
The balanced equation is ;
N₂ + 3H₂ → 2NH₃
The mole ratio is the ratio of the coefficients of the combining reactants;
1 mole of N₂ combines with 3 mole of H₂;
So;
D - matter remains constant in any chemical equation, so reactants always equal products.
