Explanation:
To balance a chemical equation implies that we are conserving the number and mass of the reacting species.
Chemical equations must obey the law of conservation of mass "in a chemical reaction, matter is neither created nor destroyed".
This suggests that mass is conserved.
The number of atoms on the reactant side must be equal to that on the product end.
Before proceeding, check the species to see if they have equal number of atoms on both sides:
Fe + CuCI₂ → FeCI₂ + Cu
Elements reactants products
Fe 1 1
Cu 1 1
Cl 2 2
We can see that the equation is already balanced

Answer: Heating a crucible to remove water from a hydrate.
Explanation:
The options are:
a. Heating a solvent to help a solute dissolve.
b. Heating an isolated solid to dry it.
c. Heating water to boiling for a water bath.
d. Heating a crucible to remove water from a hydrate.
The procedure that can be performed on a hot plate are:
a. Heating a solvent to help a solute dissolve.
b. Heating an isolated solid to dry it.
c. Heating water to boiling for a water bath.
It should be noted that the hot plate cannot be used for heating of crucible in order to remove water from a hydrate. It is not advisable for someone to heat any silica or ceramic objects on a hot plate.
Therefore, heating a crucible to remove water from a hydrate is the correct option.
Answer:
Option b
Explanation:
Henry law describes solubility of gases in liquids.
According to Henry's law, amount of gas dissolved in a liquid depends upon its partial pressure above the liquids.
Mathematically, Henry's law is represented as:
C = K × P
Where,
C = Solubility of gas or concentration of gas in liquids
K = Henry's constant
P = Partial pressure of the gas over the liquid
For, Henry's law to be valid, pressure should be not too high and temperature should not be too low. Henry's law is also valid in case of low dissolved gas concentrations.
So, among the given options, option b, temperature is correct.
