Answer:-
4.765 grams
Explanation:-
Molecular weight of Hydrogen gas H2 = 1 x 2 = 2 gram
Molecular weight of NH3 = 14 x 1 + 1 x 3 = 17 gram
The balanced chemical equation for the reaction is
N2 + 3 H2 --> 2 NH3
From the chemical equation we see
To produce 2 NH3 we need 3 H2 to react.
∴ To produce 2 x 17 grams of NH3 we need 3 x 2 grams of H2 to react.
To produce 27 grams of NH3 we need (3 x 2) x 27 / (2 x 17) grams of H2 to react
=4.765 grams of H2 to react
Answer:
Single Replacement reaction
Explanation:
Reaction Given:
2Na + 2HCI ------> H₂ + 2NaCl
Type of reaction = ?
Solution:
Look at the reactants and products of the reaction to know the type of reaction
2Na + 2HCI ------> H₂ + 2NaCl
In this reaction two reactant combine and give 2 products.
Reactant of the reaction
Na = Sodium
HCl = Hydrochloric acid
Product of the reaction
NaCl = sodium chloride
H₂ = hydrogen gas
So,
That sodium metal react with hydrochloric acid and produce salt and water gas
Type of Reaction:
This is a Single Replacement reaction, in which Sodium metal (Na) replace the Hydrogen (H) of the other compound and form Sodium Chloride salt (NaCl) and hydrogen liberate in the form of gas.
