Balance the equation KHCO3+ H3PO4 arrow K2HPO4+H20 C02.

Chemistry
1 answer:
kherson [118]3 years ago
4 0

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

What happens to the volume of a gas in a closed container if the temperature increases, but the pressure remains the same? Why?
labwork [276]

Answer:

Volume will goes to increase.

Explanation:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

So when the temperature goes to increase the volume of gas also increase. Higher temperature increase the kinetic energy and molecules move randomly every where in given space so volume increase.

Now we will put the suppose values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 4.5 L × 348 K / 298 k

V₂ = 1566 L.K / 298 K

V₂ = 5.3 L

Hence prove that volume increase by increasing the temperature.

How many molecules of CBr4 are in 250 grams of CBr4
Kazeer [188]

Answer:- 4.54*10^2^3 molecules.

Solution:- The grams of tetrabromomethane are given and it asks to calculate the number of molecules.

It is a two step unit conversion problem. In the first step, grams are converted to moles on dividing the grams by molar mass.

In second step, the moles are converted to molecules on multiplying by Avogadro number.

Molar mass of CBr_4  = 12+4(79.9)  = 331.6 g per mol

let's make the set up using dimensional analysis:

250g(\frac{1mol}{331.6g})(\frac{6.022*10^2^3molecules}{1mol})

= 4.54*10^2^3 molecules

So, there will be 4.54*10^2^3 molecules in 250 grams of CBr_4 .
