the equation below is for potassium oxide.\n4k + o₂ → 2k₂o\nwhat is the ratio of atoms of potassium to atoms of oxygen?\n○ 1:2\n○ 2:1\n○ 4:1\n○ 1:4
Answer
Explanation:
Step1: Count K atoms
In the equation (4\text{K} + \text{O}_2 \rightarrow 2\text{K}_2\text{O}), the number of K atoms is 4 (from (4\text{K})).
Step2: Count O atoms
For O, in (\text{O}_2), there are (2) O atoms (since subscript 2 means 2 atoms per (\text{O}_2) molecule).
Step3: Find the ratio
Ratio of K to O atoms: (4:2 = 2:1) (simplify by dividing both by 2).
Answer:
2:1
