How do you balance chemical equation h3po4+ca(oh)2> ca3(po4)2+h2o

The balance equation will be

3Ca(OH)2+ 2H3PO4--->Ca3(PO4)2 + 6H2O

Explanation;

The balance equation show that 3 mole of calcium hydroxide reacts with 2moles of phosphoric acid produces 1 mole of tricalcium phosphate and 6 mole of water..

Equation given is question is unbalanced

Product shows 3 Ca ions to get the same atom in reactant; multiply Ca(OH) with 3

And to get 2 phosphate ions we have to multiply phosphoric acid with 2

Now balance the number of Oxygen and hydrogen.multiply the water with 6

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
