Wow, ok, that helps a LOT!! I guess you can't very easily balance an equation that can never happen! :)
Thanks a lot!
Just to make things clear, wouldn't it have to be Mg3(PO4)2, from balancing the charges? Because PO4 is -2 and Mg is +3, so it would need to be balanced.
oops. I wrote one wrong.
H3PO4 + Mg(OH)2 --> H2O + Mg3(PO4)2
Can someone help me with these two equations I need balanced?
H2SO4 + Ca(OH)2 --> H2O + CaS
H3PO4 + Mg(OH)2 --> H2O + MgP
We've been working on these, but they're harder than we thought!
Thanks!
The reactions wont occur, and there fore can not be balanced.
Try:
H2SO4 + Ca(OH)2 --> H2O + CaSO4
H3PO4 + Mg(OH)2 --> H2O + MgPO4
Nope: Mg is +2, PO4 is -3 It is however, the Mg3(PO4)2
To balance the given chemical equations, we need to ensure that the number of each type of atom is the same on both sides of the equation.
Let's start with the first equation: H2SO4 + Ca(OH)2 -> H2O + CaS
First, count the number of atoms on both sides of the equation:
Left side:
2 hydrogen (H)
1 sulfur (S)
4 oxygen (O)
1 calcium (Ca)
Right side:
2 hydrogen (H)
1 oxygen (O)
1 calcium (Ca)
1 sulfur (S)
We need to balance the equation by adjusting the coefficients in front of each compound.
Let's balance the hydrogen atoms first. There are 2 hydrogen atoms on both sides, so we don't need to do anything for hydrogen.
Moving on to sulfur, there is 1 sulfur atom on the left side, but none on the right side. To balance sulfur, we can add a coefficient of 1 in front of CaS: H2SO4 + Ca(OH)2 -> H2O + 1 CaS
Next, let's balance the oxygen atoms. There are 4 oxygen atoms on the left side and 1 on the right side. To balance oxygen, we can add a coefficient of 4 in front of H2O: H2SO4 + Ca(OH)2 -> 4 H2O + 1 CaS
Finally, let's balance the calcium atoms. There is 1 calcium atom on the left side and 1 on the right side, so calcium is already balanced.
The balanced equation is: H2SO4 + Ca(OH)2 -> 4 H2O + CaS
Now, let's move on to the second equation: H3PO4 + Mg(OH)2 -> H2O + MgPO4
Counting the atoms:
Left side:
3 hydrogen (H)
1 phosphorus (P)
4 oxygen (O)
1 magnesium (Mg)
Right side:
2 hydrogen (H)
1 oxygen (O)
1 magnesium (Mg)
1 phosphorus (P)
We can see that the hydrogen and oxygen atoms are already balanced.
To balance the phosphorus and magnesium atoms, we need to add a coefficient of 2 in front of MgPO4: H3PO4 + Mg(OH)2 -> H2O + 2 MgPO4
The balanced equation is: H3PO4 + Mg(OH)2 -> H2O + 2 MgPO4
