the equation below is for potassium oxide. 4k + o2 → 2k2o what is the ratio of atoms of potassium to atoms of oxygen? 1:2 2:1 4:1 1:4
Answer
Explanation:
Step1: Identify potassium atoms
In the equation $4K + O_2\rightarrow2K_2O$, the coefficient of $K$ is 4, so there are 4 potassium atoms on the reactant - side. On the product - side, in $2K_2O$, the number of potassium atoms is $2\times2 = 4$.
Step2: Identify oxygen atoms
On the reactant - side, in $O_2$, the number of oxygen atoms is 2. On the product - side, in $2K_2O$, the number of oxygen atoms is also 2.
Step3: Calculate the ratio
The ratio of potassium atoms to oxygen atoms is $\frac{4}{1}$.
Answer:
4:1
