Question

question 10 (1 point) listen solute1. na₂co₃ is in water. insoluble soluble and a nonelectrolyte soluble and an electrolyte

Explanation:

Sodium carbonate ($\ce{Na2CO3}$) is an ionic compound. Compounds containing sodium ions ($\ce{Na+}$) are generally soluble in water. When dissolved, it dissociates into ions ($\ce{2Na+ + CO3^{2-}}$) and conducts electricity, so it is an electrolyte. The first option is wrong as it's soluble. The second is wrong because it's an electrolyte (not a nonelectrolyte) when dissolved. So the correct description is "soluble and an electrolyte".

Answer:

C. soluble and an electrolyte (assuming the options are labeled A: insoluble, B: soluble and a nonelectrolyte, C: soluble and an electrolyte; if labels differ, adjust to the option with "soluble and an electrolyte" text)
