15 grams of sodium reacts with a certain amount of chlorine to yield 37 grams of sodium chloride, as shown below.
1 answer:
Answer: 22g of chlorine would be needed to carry out this synthesis reaction
Explanation:
A synthesis reaction is one in which two or more than two elements combine together to forma single product.
The atoms present in the reactants are found on the product side. According to the law of conservation of mass, the number of atoms on both sides of the arrow must be same as the total mass must be conserved.
15 grams of sodium reacts with 22 grams of chlorine to yield 37 grams of sodium chloride. Thus 22g of chlorine would be needed to carry out this synthesis reaction.

Answer :
(a) The moles of water produced are 145.35 moles.
(b) The mass of oxygen needed are 3080.8 grams.
<u>Solution for part (a) : Given,</u>
Moles of = 16.15 moles
First we have to calculate the moles of
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react to give 18 moles of
So, 16.15 moles of react to give
moles of
The moles of water produced are 145.35 moles.
<u>Solution for part (b) : Given,</u>
Mass of = 878 g
Molar mass of = 114 g/mole
Molar mass of = 32 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of react with 25 moles of
So, 7.702 moles of react with
moles of
Now we have to calculate the mass of .
The mass of oxygen needed are 3080.8 grams.
