Answer:
at summer season the snow will melt and will produce water and using generators we can produce electric energy and in spring and winter can produce electric energy also using the wind
2C₃H₇OH + 9O₂ = 6CO₂ + 8H₂O
a₀=2
a₁=9
a₂=6
a₃=8
I guess d correct answer is CaCO3
Answer:
9.606 g
Explanation:
Step 1: Write the balanced combustion reaction
C₂H₆O(l) + 3 O₂(g) → 2 CO₂(g) + 3 H₂O(g)
Step 2: Calculate the moles corresponding to 11.27 g of H₂O
The molar mass of H₂O is 18.02 /mol.
11.27 g × (1 mol/18.02 g) = 0.6254 mol
Step 3: Calculate the moles of C₂H₆O that formed 0.6254 moles of H₂O
The molar ratio of C₂H₆O to H₂O is 1:3. The moles of C₂H₆O are 1/3 × 0.6254 mol = 0.2085 mol
Step 4: Calculate the mass corresponding to 0.2085 moles of C₂H₆O
The molar mass of C₂H₆O is 46.07 g/mol.
0.2085 mol × 46.07 g/mol = 9.606 g
