Answer:
Gas
Explanation:
This is kind of like the process of evaporating
Answer: Cl2
Explanation: ionic compounds forms cations and anions in water solution.
HI is a weak acid and forms H+ and I- ions. Cl2 is dissolved slightly in water
And stays in molecule form which can not transfer charge like cations and anions.
I believe the correct answer from the choices listed above is option A. The reactant for the given chemical reaction would be NaHCO3 and HCl. <span>A </span>reactant<span> is a substance that changes in a chemical reaction. It is the starting material in a reaction. Hope this answers the question.</span>
Explanation:
Number of moles equal to the given mass divided by molar mass of the element or compound.
Mathematically, No. of moles =
The given mass is g and molar mass is 24.30 g/mol.
Therefore, calculate the number of moles as follows.
No. of moles =
=
= mol
= mol
or, = 2000 mol
Thus, we can conclude that g of Mg has 2000 moles.
