<u>Answer:</u> The actual yield of the carbon dioxide is 47.48 grams
<u>Explanation:</u>
For the given balanced equation:
To calculate the mass for given number of moles, we use the equation:
Theoretical moles of carbon dioxide = 1.30 moles
Molar mass of carbon dioxide = 44 g/mol
Putting values in above equation, we get:
To calculate the theoretical yield of carbon dioxide, we use the equation:
Theoretical yield of carbon dioxide = 57.2 g
Percentage yield of carbon dioxide = 83.0 %
Putting values in above equation, we get:
Hence, the actual yield of the carbon dioxide is 47.48 grams
Answer:
THE FREEZING POINT OF A WATER SOLUTION OF FRUCTOSE MADE BY DISSOLVING 92 g OF FRUCTOSE IN 202g OF WATER IS -4.70 ◦C
Explanation:
To calculate the freezing point of a water solution of fructose,
1. calculate the molar mass of Fructose
( 12 * 6 + 1*12 + 16*6) =72 + 12 +96 = 180 g/mol
2. calculate the number of moles of fructose in the solution
number of moles = mass / molar mass
n = 92 g / 180 g/mol
n = 0.511 moles.
3. calculate the molarity of the solution
molarity = moles / mass of water in kg
molarity = 0.5111 / 202 g /1000 g
molarity = 0.5111 / 0.202
molarity = 2.529 M
4. calculate the change in the freezing point of pure solvent and solution ΔTf
ΔTf = Kf * molarity of the solute
Kf = 1.86 ◦C/m for water
ΔTf = 1.86 * 2.529
ΔTf = 4.70 C
5. the freezing point is therefore
0.00 ◦C - 4.70 ◦C = -4.70 ◦C

Answer:
a. Cellular Respiration produces more ATP than Anaerobic Respiration.
Explanation:
Cellular Respiration creates a total of 36-38 ATP per round. Anaerobic processes only produce 2 ATP per cycle.
Answer:
No
Explanation:
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture.
