Question

the reactants of a reaction are 2agclo₃ and na₂co₃. according to the law of conservation of matter, which of the following could be a product? a. agno₃ b. caco₃ c. ag₂co₃ d. naoh

Explanation:

Step1: Identify reactant elements

The reactants are $2AgClO_3$ and $Na_2CO_3$. The elements present in the reactants are silver (Ag), chlorine (Cl), oxygen (O), sodium (Na), and carbon (C).

Step2: Analyze each option

• Option A: $AgNO_3$ has nitrogen (N) which is not present in the reactants.
• Option B: $CaCO_3$ has calcium (Ca) which is not present in the reactants.
• Option C: $Ag_2CO_3$ contains only elements (Ag, C, O) that are present in the reactants.
• Option D: $NaOH$ has hydrogen (H) which is not present in the reactants.

Answer:

C. $Ag_2CO_3$
