Calcium Chloride would have a charge of +2
Hopes this helps :)
A word equation is a written description of a chemical reaction.
All word equations start with the reactants.
Then, what comes next is the word "react to form."
Finally, the products of the equation are mentioned.
An example is,
Zinc and Hypochondriac acid react to form hydrogen gas and zinc chloride.
Answer:
Mass = 3.752 g
Explanation:
Given data:
Number of moles of Li = 0.536 mol
Mass of N₂ needed = ?
Solution:
Chemical equation:
2Li + N₂ → 2LiN
Now we we will compare the moles of Li and N₂.
Li : N₂
2 : 1
0.536 : 1/2×0.536 = 0.268 mol
Mass of N₂
Mass = number of moles × molar mass
Mass = 0.268 mol × 14 g/mol
Mass = 3.752 g
The number of moles of AlBr3 = Molarity × Volume
= 0.150 × 0.3
= 0.045 moles
1 mole of AlBr3 gives 3 moles of Br- ions
That is
AlBr3 = Al3+ + 3Br-
Therefore, 0.045 moles of AlBr3 will yield 3 × 0.045 = 0.135 moles
Thus; they are 0.135 moles of bromide ions
