Answer: The mass of 
produced is, 149 grams.
Explanation : Given,
Mass of 
= 354.2 g
Molar mass of = 278 g/mol
Molar mass of = 58.5 g/mol
First we have to calculate the moles of
Now we have to calculate the moles of 
The balanced chemical equation is:
From the reaction, we conclude that
As, 3 moles of react to give 6 mole of
So, 1.27 moles of react to give 
mole of
Now we have to calculate the mass of
Therefore, the mass of produced is, 149 grams.

54.87 % O
3.457 % H
Explanation:
Thats the percent composition for each one in your question
Answer: Option (c) is the correct answer.
Explanation:
A particle that contains two protons and two neutrons bounded together is known as an alpha particle.
It is known that an alpha particle has a large mass and due to this they travel very slowly. As a result, they tend to have low velocity.
Hence, we can conclude that alpha particles cannot penetrate deeply into solids because they have low velocity.
