Write balanced equations for each of the following. Remember to use a good approach: think about what kind of chemicals are involved, what type of reaction they may be involved, what the products...

1) Na(s)+H2O(I)= NaOH(aq)+H(g) 2)PbNO2(aq)+ NaCl(aq)= PbCl(s)+ NaNO2(aq) 3)CaOH2(aq)= 2HCl(aq)= CaCl2(aq)+ 2H2O(I) 4)C2H4(g)+ 2O2(g)= 2CO2(g)+ 2H2(g) 5)...

_H2SO4+NaOH--?_H2O+_NaSO4

please do it really fast!!! THanks The scale balanced with x on one one side and 4 blocks on the other side. Your friend changed the scale, but had to leave before restoring balance...

predict the product and balance the equation and name the type of reaction

I already know how they balnace I just don't understand how they balance. why does the O(2*) balance to 25? 2 C(8*)H(18*) + 25 0(2) yields 16 CO(2*) + 18 H(2*)O These ones have me...
