If 25 g of NH3, and 96 g of H2S react according to the following reaction, what is the
1 answer:
25 g of NH₃ will produce 47.8 g of (NH₄)₂S
<u>Explanation:</u>
2 NH₃ + H₂S ----> (NH₄)₂S
Molecular weight of NH₃ = 17 g/mol
Molecular weight of (NH₄)₂S = 68 g/mol
According to the balanced reaction:
2 X 17 g of NH₃ produces 68 g of (NH₄)₂S
1 g of NH₃ will produce g of (NH₄)₂S
25g of NH₃ will produce of (NH₄)₂S
= 47.8 g of (NH₄)₂S
Therefore, 25 g of NH₃ will produce 47.8 g of (NH₄)₂S

Answer:
<h3>moles of carbon dioxide=13.95mol</h3>Explanation:
First wrie down the balance chemical reaction:
Combustion reaction: The reacion in which hydrocarbon is burnt in the presence of oxygen gas and it releases heat and this reaction exothermic because heat of cumbustion is negative.
eg. burning of methane
By using unitry method,
From the above balanced reaction it is clearly that,
from 1 mole of propane 3 moles of carbon dioxide is formed
there fore,
from 4.65 mole of propane moles of carbon dioxide will form
moles of carbon dioxide=13.95mol
The given question is incomplete. The complete question is :
For the reaction at equilibrium, which statement correctly describes the effects of increasing pressure and adding
, respectively
a) Increasing pressure causes shift to reactants, adding causes shift to products.
b) Increasing pressure causes shift to products ,adding causes shift to reactants.
c) Increasing pressure causes shift to products, adding causes shift to products.
d) Increasing pressure causes shift to reactants,adding causes shift to reactants
Answer: Increasing pressure causes shift to reactants, adding causes shift to products.
Explanation:
Any change in the equilibrium is studied on the basis of Le-Chatelier's principle.
This principle states that if there is any change in the variables of the reaction, the equilibrium will shift in the direction to minimize the effect.
For the given equation:
a) If the pressure is increased, the volume will decrease according to Boyle's Law. Now, according to the Le-Chatlier's principle, the equilibrium will shift in the direction where decrease in pressure is taking place. As the number of moles of gas molecules is lesser at the reactant side. So, the equilibrium will shift in the left direction. i.e. towards reactants.
b) If is added, the equilibrium will shift in the direction where
is decreasing. So, the equilibrium will shift in the right direction. i.e. towards products.
