Can somebody Help me Please!!??
Balance this Equation: Ca(s) + H2O(I) Ca(OH)2(aq)+H2(g)
2Ca(s) +4 H2O(I) = 2 Ca(OH)2(aq)+2H2(g) I added the ' = '
which of the two is the right answer?
That IS the answer.....a balanced chemical reaction ....
2 calciums atoms combine with 4 water molecules to produce 2 calcium hydroxides and 2 molecules of hydrogen gas (H2)
I added the = because it was missing in your original question....
