For the following reaction, 16.2 grams of carbon dioxide are allowed to react with 45.0 grams of potassium hydroxide. carbon dioxide (g) potassium hydroxide (aq) potassium carbonate (aq) water (l) What is the maximum amount of potassium carbonate that can be formed

The maximum amount of potassium carbonate that formed 49.68 g

Explanation:

According to question

                                2 KOH(aq) + CO₂(g) → K₂CO₃(aq) + H₂O(l)

16.2 grams of carbon dioxide are allowed to react with 45.0 grams of potassium hydroxide.

So, CO₂ is limiting reagent.

                1 mole CO₂ produce 1 mole K₂CO₃

∴  0.36 mole CO₂ produce 0.36 mole K₂CO₃ or (0.36 x 138)g = 49.68 g

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
