<u>Answer:</u> The solubility product of magnesium phosphate tribasic is 
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

Given mass of magnesium phosphate = 1.24 g
Molar mass of magnesium phosphate = 262.85 g/mol
Volume of solution = 1 L
Putting values in above equation, we get:

The equation for the ionization of the magnesium phosphate is given as:

Expression for the solubility product of
will be:
![K_{sp}=[Mg^{2+}]^3[PO_4^{3-}]^2](https://tex.z-dn.net/?f=K_%7Bsp%7D%3D%5BMg%5E%7B2%2B%7D%5D%5E3%5BPO_4%5E%7B3-%7D%5D%5E2)
We are given:
![[Mg^{2+}]=(3\times 4.72\times 10^{-3})=1.416\times 10^{-2}M](https://tex.z-dn.net/?f=%5BMg%5E%7B2%2B%7D%5D%3D%283%5Ctimes%204.72%5Ctimes%2010%5E%7B-3%7D%29%3D1.416%5Ctimes%2010%5E%7B-2%7DM)
![[PO_4^{3-}]=(2\times 4.72\times 10^{-3})=9.44\times 10^{-3}M](https://tex.z-dn.net/?f=%5BPO_4%5E%7B3-%7D%5D%3D%282%5Ctimes%204.72%5Ctimes%2010%5E%7B-3%7D%29%3D9.44%5Ctimes%2010%5E%7B-3%7DM)
Putting values in above expression, we get:

Hence, the solubility product of magnesium phosphate tribasic is 
<u>Answer:</u>
<em>Theoretical density values </em>
- brass-

- bronze-

- steel-

<u>Explanation:</u>
All of these substances are<em> </em>alloys (a substance made from melting two or more substances, one of them usually being a metal). Brass is a combination of copper and zinc, bronze is mostly copper, tin and other non-metals as well and steel is majorly made up of iron and copper. These alloys have various uses and varying importance in different kinds of industries.
Answer: 0.050 moles of nitrogen monoxide are produced by 0.050 moles of ammonia.
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical reaction is:

According to stoichiometry:
4 moles of ammonia produce = 4 moles of nitrogen monoxide
Thus 0.050 moles of ammonia produce =
moles of nitrogen monoxide
Maybe you can try to reduce the amount of electricity you use, that should be easy to fill out :)
