109/8.56=12.7
50+12.7
V=62.7
Mass= Volume x Density so i divided the mass and density to get the volume. and afterwards i would just add it to the mass to get my final answer
Answer:
Percentage yield is 41.21%
Explanation:
Equation of reaction,
N₂ + 3H₂ → 2NH₃
Actual NH3 = 6.83g
Mass of N2 = 5.77g
Theoretical yield = ?
5.77g of N2 = 6.83g of NH3
14g of N2 = xg
X = (14 × 6.83) / 5.77
X = 95.62 / 5.77
X = 16.57g of NH3
Theoretical yield of NH3 is 16.57g
Percentage yield = (actual yield / theoretical yield) × 100
% yield = (6.83 / 16.57) × 100
% yield = 0.4121 × 100
% yield = 41.21%
The percentage yield of NH3 is 41.21%
True I believe because when the current circuit is at its limit it will be damaged
<em>C. The shark population decreases.</em> Because the sharks will soon run out of food and dolphins are not the easiest to eat because they can fight back with their sharp teeth. And the sharks can't just stop eating. So the realty is the sharks population will most likely decrease. But the great white sharks are very big and powerful sharks so if they do move waters them most likely will be attacked by other sharks but will survive. So <em>the other possible answer could be B</em>
