Answer:
zince chloride will be formed and hydrogen gas will be librated.
Explanation:
When dilute HCl is added to zinc pieces, a rection will takes place as follows :

It means that zinc chloride will form when zinc reacts with dilute HCL. Also hydrogen gas will produced.
As zinc is more reactive than hydrogen, it displaces hydrogen from its solution and forms zinc chloride. The form product is white in color and H₂ is an odorless gas.
Hence, zince chloride will be formed and hydrogen gas will be librated.
Condensation
..when gas cool down into liquid statr its called condensation..
Answer:
If 500.0 mL of 0.450 M sodium phosphate is reacted with an excess of iron (II) nitrate solution, how many grams of iron (II) phosphate are produced?

Explanation:
Answer:
of PABA is 0.000022
Explanation:

cM 0 0

So dissociation constant will be:

Give c= 0.055 M and
= ?

![pH=-log[H^+]](https://tex.z-dn.net/?f=pH%3D-log%5BH%5E%2B%5D)
![2.96=-log[H^+]](https://tex.z-dn.net/?f=2.96%3D-log%5BH%5E%2B%5D)
![[H^+]=1.09\times 10^{-3}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D1.09%5Ctimes%2010%5E%7B-3%7D)
![[H^+]=c\times \alpha](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3Dc%5Ctimes%20%5Calpha)


Putting in the values we get:


Thus
of PABA is 0.000022
Microwave it! It just has to be defrosted.
