octane (c8h18) is one of the main components of gasoline. octane burns in oxygen gas (o2) to produce carbon dioxide (co2) and water vapor (h2o). this reaction is represented by the balanced chemical equation below. 2c8h18 (l) + 25o2 (g) → 16co2 (g) + 18h2o (g) determine the number of each type of atom in the reactants and products. number of atoms in reactants number of atoms in products c h 36 36 o
Answer
Explanation:
Step1: Calculate carbon atoms in reactants
In $2C_{8}H_{18}$, the number of carbon atoms is $2\times8 = 16$.
Step2: Calculate carbon atoms in products
In $16CO_{2}$, the number of carbon atoms is 16.
Step3: Calculate oxygen atoms in reactants
In $25O_{2}$, the number of oxygen atoms is $25\times2=50$.
Step4: Calculate oxygen atoms in products
In $16CO_{2}$, the number of oxygen atoms is $16\times2 = 32$, and in $18H_{2}O$, the number of oxygen atoms is 18. So in total, there are $32 + 18=50$ oxygen atoms.
Answer:
| Number of atoms in reactants | Number of atoms in products | |
|---|---|---|
| C | 16 | 16 |
| H | 36 | 36 |
| O | 50 | 50 |
