Answer 1

Answer on Question #66024 - Chemistry - Organic Chemistry

Task:

How many grams of H₂O are produced from 9.40 g of ethanol?

Solution:

Water = H₂O;

Ethanol = C₂H₅OH;

Ethylene = C₂H₄.

Reaction Scheme:

$$C _ {2} H _ {5} O H \xrightarrow {H ^ {+}} C _ {2} H _ {4} + H _ {2} O$$

By the equation:

$$\begin{array}{l} n C H Q H) = n (H Q); \\ \frac {m C H Q H)}{M C H Q H)} = \frac {m (H _ {2} O)}{M H Q)}; \\ m (H _ {2} O) = \frac {M (H _ {2} O) \times m C H Q H)}{M C H Q H)}; \\ m (H _ {2} O) = \frac {1 8 \times 9 . 4 0}{4 6} \approx 3. 6 8 (g) \\ \end{array}$$

Answer: 3.68 g H₂O.
