The size of a hydrogen atom is about 1.2 * 10 ^ - 10 m across. The size of an oxygen atom is 0.000000000152 m across. What is the difference between the sizes of these atoms in scientific notation? (1 point)
The difference between the sizes of these atoms can be found by subtracting the size of the hydrogen atom from the size of the oxygen atom:
0.000000000152 m - 1.2 * 10^-10 m
To subtract these values, we need to express them in the same power of 10. Let's convert 0.000000000152 m to scientific notation:
0.000000000152 m = 1.52 * 10^-10 m
Now we can subtract the values:
1.52 * 10^-10 m - 1.2 * 10^-10 m = (1.52 - 1.20) * 10^-10 m = 0.32 * 10^-10 m
Finally, we can convert the result to scientific notation:
0.32 * 10^-10 m = 3.2 * 10^-11 m
Therefore, the difference between the sizes of these atoms is 3.2 * 10^-11 m.
