Answer:
86
Explanation:
The reaction that takes place is:
- C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
First we <u>convert moles of ethanol to moles of water</u>:
- 1.6 mol ethanol *
= 4.8 mol H₂O
Then we <u>convert moles of water to grams of water</u>, using its molar mass:
- 4.8 mol H₂O * 18 g/mol = 86.4 g
So 84.6 grams of water will be produced.
Answer:
i think it is the last option a pure substance that can be separated into different elements by chemical means
Explanation:
Answer:
Explanation:
An example of binary compund is ZnI2 is zinc iodide
Answer:
4 moles of water
Explanation:
this is a combustion reaction, so the balanced equation is: 2C2H6 + 7O2 → 4CO2 + 6H2O.
the molar mass of C2H6 is 30.07g, so 40.0 g of C2H6 is 1.33 moles of C2H6.
mole ratio of H2O to C2H6 is 6/2, or 3.
1.33 moles C2H6 * 3 moles H2O/1 mole C2H6 = 4 moles H2O
