Question

To determine how many grams of calcium hydroxide is needed, how much water is needed and how many grams of sodium hydroxide are formed when 500g of sodium carbonate reacts with calcium hydroxide, we need to consider the balanced chemical equation for the reaction. The balanced chemical equation for the reaction between sodium carbonate (Na2CO3) and calcium hydroxide (Ca(OH)2)

Answer 1

The question is related to calculating the required amount of calcium hydroxide in a chemical reaction using sodium carbonate to produce sodium hydroxide. The answer involves stoichiometry based on the balanced equation.

Step-by-step explanation:

The student is asking about a specific chemical reaction involving sodium carbonate (Na2CO3) and calcium hydroxide (Ca(OH)2) to produce sodium hydroxide (NaOH) and another compound, which in this case requires clarification, as the chemical equations provided in the question references different reactions.

However, the typical reaction between sodium carbonate and calcium hydroxide would be as follows:

• Na2CO3 (aq) + Ca(OH)2 (s) → 2 NaOH (aq) + CaCO3 (s)

To determine how much calcium hydroxide is needed, one would use stoichiometry based on the balanced equation to calculate the amount of reactants needed to produce a certain amount of sodium hydroxide or any other product in the reaction.
