Can you balance this chemical equation?

Question

__KHCO3 + __H3PO4 yields __K2HPO4 + __H2O + __CO2

Can you solve it? Show your work please...

Answer 1

When you want to balance ANY chemical equation, always follow these steps:

1. Balance metals
2. Balance non-metals
3. Balance hydrogen
4. Balance oxygen

Let's do it

First let's balance K (metal):

"2" KHCO3 + __H3PO4 yields __K2HPO4 + __H2O + __CO2

done. now let's balance P (non metal): if you check, it is balanced already.

now C (also non metal):

2 KHCO3 + __H3PO4 yields __K2HPO4 + __H2O + "2" CO2

now hydrogen:

2 KHCO3 + __H3PO4 yields __K2HPO4 + "2" H2O + 2 CO2

finally, oxygen (its already balanced!!)

So you end with

2 KHCO3 + H3PO4 yields K2HPO4 + 2 H2O + 2 CO2

Answer 2

well,,,,

start with the distribution of atoms BEFORE you start balancing....

K 1, 2

So, you know you have to put at least a 2 in the very front.

_2_KHCO3 + __H3PO4 yields __K2HPO4 + __H2O + __CO2

that gives us then two carbons on the left, so we need two carbons on the right

_2_KHCO3 + __H3PO4 yields __K2HPO4 + __H2O + _2_CO2

now, we have five hydrogen on the left, on the right, there is one in K2HPO4 and two in H20, so, I can double the water...

_2_KHCO3 + __H3PO4 yields __K2HPO4 + _2_H2O + _2_CO2

there's one Phosphorus on each side, that's cool, and ten Oxygens.on the left ( 6 plus 4) .. on the right we have 4 + 2 + 4 is ten, cool. We're done.

Answer 3

2 KHCO3 + H3PO4 --> K2HPO4 + 2 H2O + 2 CO2

Answer 4

2KHCO3 + 1H3PO4 -----> 1K2HPO4 + 2H2O + 2CO2

Element by element analysis
products ------------> reactant
2K --------------------> 2K
2H + 3H = 5H-------> H + 4H = 5H
2C --------------------> 2C
6O + 4O =10 O----> 4 O + 2 O + 4 O = 10 O
1P --------------------> 1P

it checks.

Answer 5

2KHCO3 + H3PO4 ----> K2

Answer 6

P2O5 +KHCO3 =
