When the following equation is balanced with the lowest whole number coefficients possible, what is the coefficient in front of ca(oh)2? ca(oh)2 + h3po3 yields h2o + ca3(po3)2

Ans: Lowest coefficient in front of Ca(OH)2 is 3

Given equation:

Ca(OH)2 + H3PO3 → Ca3(PO3)2 + H2O

Reactants:                  Products:

Ca = 1                          Ca = 3

O = 5                           O = 7  

H = 5                           H = 2

P = 1                             P = 2

Balanced equation:

3Ca(OH)2 + 2H3PO3 → Ca3(PO3)2 + 6H2O

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
