The system that relates to the process by which an organism get rid of its waste is Excretory.
Answer:
305 g of CO₂
3.77 × 10⁵ kJ
Explanation:
Let's consider the global reaction for photosynthesis.
6 CO₂(g) + 6 H₂O(l) → C₆H₁₂O₆(g) + 6 O₂(g) ΔHrxn = 2802.8 kJ
<em>A 1.70 lb sweet potato is approximately 73% water by mass. If the remaining mass is made up of carbohydrates derived from glucose (MW = 180.156 g/mol), how much carbon dioxide (MW = 44.01 g/mol) was needed to grow this sweet potato?</em>
<em />
Let's consider the following relations:
- The potato is 100%-73%=27% glucose by mass.
- 1 lb = 453.59 g.
- 6 moles of CO₂ produce 1 mole of glucose.
- The molar mass of glucose is 180.156 g/mol.
- The molar mass of carbon dioxide is 44.01 g/mol.
Then, for a 1.70 lb potato:

<em>How much light energy does it take to grow the 1.70 lb. sweet potato if the efficiency of photosynthesis is 0.86%?</em>
<em />
According to the enthalpy of the reaction, 2802.8 kJ are required to produce 1 mole of glucose. Then, for a 1.70 lb potato:

Answer:
24 molecules of phosphorus trichloride can be formed
Explanation:
Based on the equation:
P4(s) + 6Cl2(g) → 4PCl3
<em>1 mole of P4 reacts with 6 moles of Cl2 to produce 4 moles of PCl3.</em>
<em />
When 10 molecules of P4 react, 60 molecules of Chlorine are needed. As there are just 36 molecules, Cl2 is limiting reactant.
If 36 molecules of chlorine are added, molecules of PCl3 produced are:
36 molecules Cl2 * (4 PCl3 / 6 Cl2) =
24 molecules of phosphorus trichloride can be formed
there are 92 naturally occuring elements
