Answer:
salt mass=102.5gCrCl3.6H2O
Explanation:
Hello !
To know how much CrCl3.6H2O we need, we follow the steps below
First we have to know what the mass of the compound is
Cr = 52g / mol
Cl = 35.5g / mol
H = 1g / mol
O = 16g / mol
We calculate the mass
52+ (35.5 * 3) + 6 * (2 * 1 + 16) = 266.5g
We have 20g Cr, so we calculate the amount of salt:
20gCr * (266.5g salt / 52gCr) = 102.5gCrCl3.6H2O
salt mass=102.5gCrCl3.6H2O

Answer: (a) The products are and AgCl. The balanced equation is .
(b) The type of reaction is double displacement reaction.
Explanation:
(a) The complete reaction equation will be as follows.
Number of atoms on reactant side are as follows.
- Be = 1
- Cl = 2
- Ag = 2
- = 2
Number of atoms present on product side are as follows.
- Be = 1
- Cl = 2
- Ag = 2
- = 2
Here, number of atoms on both reactant and product side are the same. Hence, it is a balanced chemical equation.
(b) A reaction in which two reactant species tend to change their ions with each other and form new compounds. This type of reaction is called double displacement reaction.
As the given reaction is as follows.
This shows that ions are being exchanges by the reactants and
. The ions are , , and .
Therefore, this reaction is a double displacement reaction.
