Question

Which of the following gives the balanced equation for this reaction? K_3PO_4 + Ca(NO_3)_2 rightarrow Ca_3(PO_4)_2 + KNO_3 KPO_4 + CaNO_3 + KNO_3 K_3PO_4 + Ca(NO_3)_2 rightarrow Ca_3(PO_4)_2 + 6KNO_3 2K_3PO_4 + Ca(NO_3)_2 rightarrow Ca_3(PO_4)_2 + 6 KNO_3 2K_3PO_4 + 3Ca(NO_3)_2 rightarrow Ca_3(PO_4)_2 + KNO_3 The volume of a gas with a pressure of 1.2 atm increases from 1.0 L to 4.0 L.
