How to balance the equation?

Question

Hi, I really need help with this one: balance and find the last product

HC2H3O2+Ba(OH)2=H2O+?

Can some chemistry genious help me?

Thank you!!! =)

Answer 1

H2OC2

you have to make sure that you have the same number of every type of atom on both sides. you have four H, two C and two O on the left. you've used two H and one O. that leaves two H, one O and two C.

Answer 2

Okay, this is a simple acid/bace equation.

The "H" from the Acetic Acid will combine with the "OH" from your base to produce H20.

You can use the formula for double displacement (Ax +By -> Bx + Ay) to combine the Acetate with the Barium.

So, you have:

HC2H3O2 + Ba(OH)2 -> H2O + Ba(C2H3O2)2

Since Barium has a charge of +2 and Acetate has a charge of -1, you need 2 Acetate compounds to balance their charge.

Now, you need to count the elements on each side of the equation, to make sure they are balanced.

There are 6 H atoms on the left side, but there are 8 H atoms on the right side.

There are 2 atoms of C on the left side of the equation, but there are 4 on the right.

There are 4 atoms of O on the left side, but there are 5 on the right side.

And there are 2 atoms of Ba on both sides.

So, the H, C, and O need to be balanced.

By placing coefficients in front of compounds in the formula, you can easily balance the equation.

Balanced equation:

2 HC2H3O2 + Ba(OH)2 -> 2 H20 + Ba(C2H3O2)2

To check, again count the number of elements on each side of the equation.

There are 10 H atoms on both sides, 4 C atoms on both sides, 6 O atoms on both sides, and 2 Ba atoms on both sides.

The chemical equation is balanced.
