ethanol is a chemical that is used in many hand sanitizers. it is produced when steam reacts with the chemical ethylene. consider the following reaction: 10 molecules of ethylene (c2h4) react with 10 molecules of water (h2o) to produce some amount of ethanol (c2h6o). complete the table below. chemical element number of atoms in the reaction h c o during this reaction, how many molecules of ethanol (c2h6o) are produced?
Answer
Explanation:
Step1: Calculate number of H atoms
In 10 molecules of $C_2H_4$, number of H atoms is $10\times4 = 40$. In 10 molecules of $H_2O$, number of H atoms is $10\times2=20$. Total H atoms: $40 + 20=60$.
Step2: Calculate number of C atoms
In 10 molecules of $C_2H_4$, number of C atoms is $10\times2 = 20$.
Step3: Calculate number of O atoms
In 10 molecules of $H_2O$, number of O atoms is $10\times1 = 10$.
Step4: Determine number of ethanol molecules
The balanced chemical - equation for the reaction is $C_2H_4+H_2O\rightarrow C_2H_6O$. Since the ratio of $C_2H_4$ to $H_2O$ to $C_2H_6O$ is 1:1:1, and we have 10 molecules of $C_2H_4$ and 10 molecules of $H_2O$, the number of $C_2H_6O$ molecules produced is 10.
Answer:
| Chemical element | Number of atoms in the reaction |
|---|---|
| H | 60 |
| C | 20 |
| O | 10 |
| Number of ethanol molecules produced: 10 |
