Answer:
number of hydrogen atom in 1.8 mole of NH2OH =
Explanation:
percentage of hydrogen in NH2OH = mass of hydrogen / mass of whole molecule
=\times 100
= 9.09 percentage
therefore number of moles in 1.8 moles of hydroxy amine =
= .16 moles of hydrogen
number of hydrogen atom = (number of moles )×(avagadro number)
= atoms of hydrogen
Answer: Option (B) is the correct answer.
Explanation:
It is known that for writing a chemical reaction equation, reactants are written on left hand side whereas products are written on right hand side.
And in between reactants and products a forward arrow is placed pointing towards the products.
Therefore, the reaction for carbon burns in the presence of oxygen to give carbon dioxide will be written as follows.
Here, carbon and oxygen atoms are the reactants whereas carbon dioxide is the product.
Answer:
a) No. of moles of hydrogen needed = 5.4 mol
b) Grams of ammonia produced = 27.2 g
Explanation:
a)
No. of moles of nitrogen = 1.80 mol
1 mole of nitrogen reacts with 3 moles of hydrogen
1.80 moles of nitrogen will react with
= 1.80 × 3 = 5.4 moles of hydrogen
b)
No. of moles of hydrogen = 2.4 mol
It is given that nitrogen is present in sufficient amount.
3 moles of hydrogen produce 2 moles of
2.4 moles of hydrogen will produce
=
Molar mass of ammonia = 17 g/mol
Mass in gram = No. of moles × Molar mass
Mass of ammonia in g = 1.6 × 17
= 27.2 g
