o never mind i figured it out

how would you write phosphoric acid and calcium hydroxide in a double replacement reaction?

2NaCl + F2 --> 2NaF +Cl2
2AgNO3 + MgCl2 --> 2AgCl + Mg(NO3)2
2AlBr3 + 3K2SO4 --> 6KBr + Al2(SO4)3

there are the first three

i did an experiment for class and was told to write the formula. the things i used were sodium hydroxide, zinc nitrate, water, and sulfuric acid. (those are the reactants i think) we put them all in one beaker and got a solution. now i have to write a chemical formula and i cant figure it out. my te...
