Answer:
There are 6.022x10^23 molecules
Answer:
3.67 mol Cl
Explanation:
We need to convert g of Cl 2 to moles of Cl. First we divide 130 gCl2 by the molar mass (70.90 gCl2/mol) to find out how many moles of Cl2 do we have.
130 gCl2 x
= 1.83 mol Cl2
Then we need to convert 1.83 mol de Cl2 to moles of Cl. We have 2 moles of Cl in every Cl2 molecule so we just need to multiply by 2.
1.83 molCl2 x
= 3.67 molCl
Limiting reactant in this experiment would be Magnesium since it will run out first
Answer:
the solubility increases
Explanation:
The solubility of any ionic compound is due to the ionization of the compound and then the strong ion-dipole interactions acting between the ions and the solvent.
Thus, solubility also depends on the extent of the ionization of the salt.
The more the salt ionizes, the more there is ion-dipole interaction between the ions the solvent and more is the solubility.
Answer: b
Explanation:
By adding heat you are adding more energy
