Question

1) Ca(PO4)2+SiO2+C-->CaSiO3+P+CO

Answer 1

Ca3(PO4)2 + 3SiO2 + 5P = 3CaSiO3 + 2P + 5CO

Answer 2

The balanced chemical equation for the reaction is:

3Ca(PO4)2 + 2SiO2 + 5C → 2CaSiO3 + 6P + 5CO

Explanation:

To balance the equation, we need to make sure that the number of atoms of each element is equal on both sides of the equation. Here's how we can balance this equation:

First, let's count the number of atoms of each element on the reactant and product sides:

Reactants: Ca = 3, P = 2 x 3 x 4 = 24, Si = 2, O = 2 x 4 x 2 + 2 x 2 = 20, C = 5 Products: Ca = 2, Si = 1, O = 3 x 2 x 2 + 3 = 15, P = 6, C = 5

Now, we can balance the equation by adjusting the coefficients:

3Ca(PO4)2 + 2SiO2 + 5C → 2CaSiO3 + 6P + 5CO

The coefficient 3 in front of Ca(PO4)2 is needed to balance the 3 Ca atoms. The coefficient 2 in front of SiO2 is needed to balance the 2 Si atoms. The coefficient 5 in front of C is needed to balance the 5 C atoms. Finally, the coefficients 2, 6, and 5 in front of CaSiO3, P, and CO, respectively, are needed to balance the rest of the atoms on the product side.
