Question

How many molecules of water are made from the reaction of 25 moles of HCI with excess oxygen?

Given the reaction: 4 HCl + O₂ → 2 H₂O +2 Cl₂
a. 8.3 x 10⁻²³
b. 1.9 x 10⁻²⁵
c. 2.1 x 10⁻²³
d. 1.5 x 10²⁵
e. 3.8 x 10²⁴
f. 3.0 x 10²⁵

Answer 1

The question is unclear because it provides information on the hydrogen and oxygen reaction to form water, not HCI and oxygen. Assuming the question meant hydrogen, the reaction between 25 moles of hydrogen and oxygen would hypothetically yield 50 moles or 3.0 × 10²µ molecules of water.

Step-by-step explanation:

The question pertains to predicting the quantity of water molecules formed from the reaction of a given amount of hydrochloric acid (HCI) with oxygen. However, there is no balanced chemical equation provided for the reaction between HCI and oxygen to produce water. Instead, the provided reference information discusses the reaction between hydrogen gas (H₂) and oxygen gas (O₂) to make water (H₂O). According to the information given and the balanced chemical equation:

2 H₂(g) + O₂(g) → 2 H₂O(l)

we can identify that two moles of hydrogen react with one mole of oxygen to produce two moles of water. If we were given 25 moles of hydrogen gas instead of HCI, the reaction would produce 50 moles of water since the ratio is 2 moles of H₂ to 2 moles of H₂O. To find the number of molecules, we would use Avogadro's number (6.022 × 10²³ molecules per mole), resulting in:

50 moles of H₂O × 6.022 × 10²³ molecules/mole = 3.0 × 10²µ molecules of H₂O

This calculation is purely hypothetical based on the reaction of hydrogen with oxygen as no valid reaction between HCI and oxygen to form water directly is provided in the question.
