Question

Quizplus · Accepted Answer

Calcination involves heating a substance in the absence of air or oxygen to convert it into a more stable form. In this case, NiCO₃ is being heated, and the products are NiO and CO₂ gas. Option A involves the addition of CaO, which is not mentioned in the question. Option C involves the addition of C (carbon), which is not mentioned in the question. Option D involves the addition of SiO₂, which is not mentioned in the question. Therefore, option B is the correct balanced equation for the calcination of NiCO₃.
