Write the complete balanced equation for the following reaction: cacl2 + na3po4 --> nacl + ca3(po4)2

Explanation:

Hello,

In this case, the required balanced chemical reaction is:

At first, 3 calciums are needed at the reactants to balance it, therefore, 2 phosphates are needed at the reactants as well, for that reason, a six is needed at the sodium chloride to balance chlorine and consequently sodium

Best regards.

6.59.

Explanation:

∵ pOH = - log[OH⁻]

∴ pOH = - log[OH⁻] = - log(3.9 x 10⁻⁸) = 7.408.

∵ pH + pOH = 14.0.

∴ pH = 14.0 - pOH = 14.0 - 7.408 = 6.59.
