Three. There’s 2 atoms in hydrogen and there’s 1 atom in oxygen.
23.9 11.00 would be the wrong answer because I guessed
Answer:
1.7L
Explanation:
Given parameters:
Volume of hydrogen gas = 1.7L
Unknown:
Volume of water produced = ?
Solution:
A synthesis reaction is a combination reaction that involves two or more substances combining together to give a product.
In the synthesis of water, hydrogen gas and oxygen gas are reacted to give water as a product according to the expression below;
2H₂ + O₂ → 2H₂O
Assuming that the reaction takes place at STP, it is easier to solve this problem.
Now, oxygen gas must be the excess reactant because it is freely available.
Find the number of moles of the known specie first,
Number of moles = 
Number of moles of H₂ =
= 0.076moles
From the balanced reaction equation;
2 moles of H₂ produced 2 moles of H₂O
0.076 moles of H₂ will produce 0.076 moles of H₂O;
Volume of water produced = number of moles x 22.4
= 0.076 x 22.4
= 1.7L
The new volume of the gas that has an initial pressure of 5.6 x 10⁵ Pa is 5.7L. Details about volume of the gas can be found below.
<h3>How to calculate volume?</h3>
The volume of a gas can be calculated using the Boyle's law equation as follows:
P1V1 = P2V2
Where;
- P1 = initial pressure
- P2 = final pressure
- V1 = initial volume
- V2 = final volume
1.53 × 5.6 × 10⁵ = 1.5 × 10⁵ × V2
8.568 × 10⁵ = 1.5 × 10⁵V2
V2 = 8.57 × 10⁵ ÷ 1.5 × 10⁵
V2 = 5.7L
Therefore, the new volume of the gas that has an initial pressure of 5.6 x 10⁵ Pa is 5.7L.
