Question

How do I balance this chemistry equation? Na3PO4 + Cr(NO3)3 = Na(NO3)3 + CrPO4

a) 2Na₃PO₄ + 3Cr(NO₃)₃ = 6Na(NO₃)₃ + CrPO₄
b) 3Na₃PO₄ + 2Cr(NO₃)₃ = 3Na(NO₃)₃ + 2CrPO₄
c) Na₃PO₄ + Cr(NO₃)₃ = Na(NO₃)₃ + 2CrPO₄
d) 2Na₃PO₄ + 3Cr(NO₃)₃ = 2Na(NO₃)₃ + CrPO₄

Answer 1

The balanced chemical equation for the reaction between sodium phosphate and chromium nitrate is option b: 3Na₃PO₄ + 2Cr(NO₃)₃ = 3NaNO₃ + 2CrPO₄.

Step-by-step explanation:

The correct balanced chemical equation for the reaction between sodium phosphate (Na₃PO₄) and chromium nitrate (Cr(NO₃)₃) to form sodium nitrate (NaNO₃) and chromium phosphate (CrPO₄) is option b, which is written as follows:

3Na₃PO₄ + 2Cr(NO₃)₃ = 3NaNO₃ + 2CrPO₄

By comparing the number of atoms of each element on both sides of the equation, we can see that they are equal, meaning that the equation is balanced. This result is obtained by applying the law of conservation of mass, which states that the same number of atoms of each element must appear on both sides of a chemical equation.
