Answer: hello your question has some missing details attached below is the missing details
answer : 25.5% ( B )
Explanation:
<u>Determine percentage yield </u>
molar mass = 35 g/mol
mass of Li₃N(s) = 70 g
product LiH(s) = 8.0 g ( actual yield )
theoretical yield ( LiH ) = 4 * 7.95 = 31.8 g
percentage yield = actual yield * 100 / theoretical yield
= 8 * 100/31.8
= 25.5%
The balanced chemical equation between nitric acid and calcium hydroxide is:
2HNO3 (aq) + Ca(OH)2 (aq) ---> Ca(NO3)2 (aq) + 2H2O (l)
Calcium oxide has the chemical formula Ca(OH)2, while nitric acid has the formula HNO3. Salt (an ionic substance created by the reaction of an acid and a base) and water are the byproducts of the reaction between an acid and a base.
Now, to balance the equation, we have to make sure there are the same number of atoms (or ions) on both sides of the equation. Also, we must list the state of each compound in the equation.
HNO3 (aq) + Ca(OH)2 (aq) ---> Ca(NO3)2 (aq) + H2O (l)
We must balance the equation because the number of atoms on each side is not equal. To the right of the chemical formulas, put the balancing numbers.
The balanced chemical equation between nitric acid and calcium hydroxide has the equal amount of atoms on both sides as a result.
2HNO3 (aq) + Ca(OH)2 (aq) ---> Ca(NO3)2 (aq) + 2H2O (l)
