Answer:
yes
Explanation:
This can be fixed by multiplying the product contacting nitrogen by 2. o The new chemical equation is N2 +H2 →2 NH3 Reactants Products Nitrogen 2 2 Hydrogen 2 6 Since NH3 is multiplied by a coefficient of 2 there are now 2 nitrogens and 6 hydrogens. The 6 hydrogens come from the 2 multiplied by the subscript of 3.
The value of X is 2
The total amount of sample taken is 2.00 g
The amount of sample left in the oven after drying is 1.565g
The amount of sample lost (mass of water driven out) = Total sample-Anhydrous salt left in the oven
= 2.00 - 1.565
= 0.435 grams
The moles of anhydrous salt present in the hydrate = 1.565g/129.83g/mol = 0.01205
The moles of water present in the hydrate = 0.4350g/18.01g/mol = 0.02415
Therefore the ratio of these two are in 1:2 ratio
The complete chemical reaction is CoCl2.2H20

The balanced equation for the above reaction is as follows;
Mg + 2HCl ---> MgCl₂ + H₂
stoichiometry of HCl to MgCl₂ is 2:1
we have been told that Mg is in excess therefore HCl is the limiting reactant
number of HCl moles reacted - 0.100 mol/L x 0.0256 L = 0.00256 mol
according to molar ratio, number of MgCl₂ moles formed - 0.00256/2
Therefore number of MgCl₂ moles formed - 0.00128 mol
mass of MgCl formed - 0.00128 mol x 95.20 g/mol = 0.122 g
