Answer:

2KHCO3+ H3PO4 arrow  K2HPO4 + 2 H20 + 2C02

Explanation:

2KHCO3+ H3PO4 arrow  K2HPO4 + 2 H20 + 2C02

Start with the Ks. Don't start on the right. Just balance the Ks on the left. The reason is that the CO3 is going to break down as well.

2KHCO3+ H3PO4 arrow  K2HPO4 +  H20 + C02

Leave the PO4 alone. Now look at the Hs that are on the right. There are 5 on the left. Leave the K2HPO4 alone. If you put a 2 in front of tthe H2O then you have a total of 5 Hs on the right.

2KHCO3+ H3PO4 arrow  K2HPO4 + 2H20 + C02

There are 2 carbons on the left. You need 2 on the right.

2KHCO3+ H3PO4 arrow  K2HPO4 + 2H20 + 2C02

That should do it.

Let's make a table to show balance.

Species      K              H          C         PO4-         O  

Left             2              5           2          1                6 from CO3^(2-)  

Right           2              5           2          1                6 from H2O/CO2

Which of the following statements is true?
EastWind [94]
The first statement is False... as
For exothermic reaction :
A+B》 C+D + HEAT..(heat is considered as a product)... as for endo.. heat is a reactant.
So tjey can't be of the same energy...

2nd one...based on the
A+B》 C+D+HEAT...For exo reaction... the product have more Heat energy than potential...so its false
Recall...energy can nither be created nor destroyed but converted from one form to another....

The 4th one however is true for heat...the reactants have nore energy than the products..
A+B+HEAT》C+D

When is balance achieved between the forward and reverse reactions?
docker41 [41]

Equilibrium occurs when forward and reverse directions of a reversible reaction occur at the same rate so there is no overall change in the amounts of reactants and products.
