Stage 1
Answer 6 questions correctly in a row.
Acetaldehyde is a substance commonly used in chemical factories. It is often produced by combining ethylene gas and oxygen gas.
Consider the following reaction:
2 molecules of ethylene
()
react with 1 molecule of oxygen C
2
H
4
()
to produce some amount of acetaldehyde O
2
().
C
2
H
4
O
To find the amount of acetaldehyde produced, first determine the number of each type of atom in the products.
Hint: During a chemical reaction, atoms are not created, destroyed, or changed from one chemical element to another.
| Chemical element | Number of atoms in reactants | Number of atoms in products |
| H | 8 | |
| C | 4 | |
| O | 2 |
