2H3PO4 + 3Ca(OH)2 ➡ Ca3(PO4)2 + 6H2O.

Hence salt formed is Ca3(PO4)2.
Hope this helps, have a nice day!

Answer:

The formula for the salt formed is Ca(HPO4)

Explanation:

When an acid reacts with a base, there is a salt formation. Sometimes the replacement of the hidrogens in the acid by the cation of the base is complete, and sometimes there is a partial replacement,as in the presente case. Here, the cation of the base is Ca2+ and it will reacts with the anion HPO4- of the acid.

H3PO4 + Ca(OH)2 ⇒ Ca(HPO4) + 2H2O

As you can see, water is also formed as a product of the reaction.

Summarizing, the formula for the salt formed is Ca(HPO4)

12.23 g of ammonia (NH3) are dissolved in enough water to make 560.0 mL of solution. How many moles of NH3 are added to the wate

Karolina [17]

Answer:

0.719 moles of NH₃

Explanation:

Molar mass of ammonia 17 g/mol

Mass of amonia = 12.23 g

Mass / Molar mass = Moles

12.23 g / 17 g/mol = 0.719 moles

What pressure is required to achieve a co2 concentration of 7.90×10−2 m at 20∘c?

Savatey [412]

Answer:- 1.90 atm

Solution:- It is based on combined gas law equation, PV = nRT

In this equation, P is pressure, V is volume, n is moles of gas, R is universal gas constant and T is kelvin temperature.

If we divide both sides by V then:

$P=\frac{nRT}{V}$

We know that, molarity is moles per liter. So, in the above equation we could replace $\frac{n}{V}$ by molarity, M of the gas. The equation becomes:

P = MRT

T = 20 + 273 = 293 K

M = $7.9*10^-^2$

Let's plug in the values in the equation:

P = $(7.9*10^-^2)(0.0821)(293)$

P = 1.90 atm

So, the pressure of the gas is 1.90 atm.
