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)
To find the difference between the sizes of these atoms, we need to subtract one size from the other.
The size of the hydrogen atom is 1.2×10^−10 m and the size of the oxygen atom is 0.000000000152 m.
To find the difference, we can subtract the two sizes:
0.000000000152 m - 1.2×10^−10 m
To subtract these numbers, we need to make sure they are in the same format.
We can represent 0.000000000152 as 1.52×10^−10 m by moving the decimal point 9 places to the right.
Now we can subtract:
1.52×10^−10 m - 1.2×10^−10 m
To subtract these numbers, we need to have the same base, so we can rewrite them as:
1.52×10^−10 m - 0.12×10^−9 m
Now we can subtract:
1.52 - 0.12 = 1.4
The difference between the sizes of the atoms is 1.4 times 10^-10 m.
In scientific notation, this is written as 1.4×10^−10 m.

Apologies for the mistake.
To find the difference between the sizes of the atoms, we can subtract the size of the hydrogen atom from the size of the oxygen atom.
The size of the hydrogen atom is 1.2×10^−10 m and the size of the oxygen atom is 0.000000000152 m.
To subtract them, we need to write both sizes in the same units.
Since 0.000000000152 m is already in standard decimal notation, we can rewrite 1.2×10^−10 m as 0.00000000012 m (by moving the decimal point 10 places to the right).
Now we can subtract the sizes:
0.000000000152 m - 0.00000000012 m = 0.000000000032 m
Since the result is already in standard decimal notation, we can convert it to scientific notation by moving the decimal point 10 places to the left:
0.000000000032 m = 3.2×10^-11 m
The difference between the sizes of these atoms is 3.2×10^-11 m.
