Question

3Ca+2H3PO4=Ca3(PO4)2+3H2​

Answer 1

Ответ:

Объяснение:

3Ca+2H3PO4=Ca3(PO4)2+3H2​

3×40+2×(3×1+31+4×16)=3×40+2×(31+4×16)+6×1

316=316

Answer 2

The equation you provided is a balanced chemical equation for the reaction between calcium (Ca) and phosphoric acid (H3PO4). The balanced equation is:

3Ca + 2H3PO4 → Ca3(PO4)2 + 3H2

In this reaction, three moles of calcium (3Ca) react with two moles of phosphoric acid (2H3PO4) to produce one mole of calcium phosphate (Ca3(PO4)2) and three moles of hydrogen gas (3H2). The coefficients in the balanced equation represent the stoichiometric ratios between the reactants and products.
