Answer : The mole ratio of hydrogen to ammonia is, 3 : 2
Explanation :
Balanced chemical reaction : The chemical reaction in which the number of individual atoms of an element present on the reactant side always be equal to the number of individual atoms of an element present on the product side.
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that 1 mole of gas react with 3 moles of
gas to give 2 moles of
gas as a product.
The mole ratio of nitrogen, hydrogen and ammonia is, 1 : 3 : 2
Therefore, the mole ratio of hydrogen to ammonia is, 3 : 2
<u>Answer:</u> The density of liquid is
<u>Explanation:</u>
We are given:
Mass of cylinder, = 65.1 g
Mass of liquid and cylinder combined, M = 120.5 g
Mass of liquid, =
To calculate density of a substance, we use the equation:
We are given:
Mass of liquid = 55.4 g
Volume of liquid = 49.3 mL = (Conversion factor:
)
Putting values in above equation, we get:
Hence, the density of liquid is
Answer:
The final balanced equation is :
Explanation:
Balancing in acidic medium:
First we will determine the oxidation and reduction reaction from the givne reaction :
Oxidation:
Balance the charge by adding 2 electrons on product side:
....[1]
Reduction :
Balance O by adding water on required side:
Now, balance H by adding on the required side:
At last balance the charge by adding electrons on the side where positive charge is more:
..[2]
Adding [1] and [2]:
The final balanced equation is :
