40.2 grams of Hydrogen Chloride (HCl) is decomposed. 12 grams of Chlorine (Cl) is formed. How many grams of Water (H2O) was formed?

3.05 g

Explanation:

The reaction that takes place is:

4HCl + O₂ → 2Cl₂ + 2H₂O

As the decomposition not necessarily was complete we'll work with the given mass of product formed. We convert the 12 grams of chlorine to moles, using its molar mass:

12 g ÷ 70.906 g/mol = 0.169 mol

Then we convert Cl₂ moles to H₂O moles:

0.169 mol Cl₂ * = 0.169 mol H₂O

Finally we convert moles to grams:

0.169 mol H₂O * 18 g/mol = 3.05 g

The kinetic energy of the liquid increases. hope this !

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.
