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)
2.72 * 10 ^ - 19 * m
3.2 * 10 ^ - 10 m
3.2 * 10 ^ - 11 m
3.2 * 10 ^ - 9 * r
The difference between the sizes of the hydrogen and oxygen atoms can be calculated by subtracting the size of the hydrogen atom from the size of the oxygen atom.
Size of hydrogen atom = 1.2 * 10^-10 m
Size of oxygen atom = 0.000000000152 m = 1.52 * 10^-10 m
Difference = Size of oxygen atom - Size of hydrogen atom
Difference = 1.52 * 10^-10 m - 1.2 * 10^-10 m
Difference = 0.32 * 10^-10 m = 3.2 * 10^-11 m
Therefore, the difference between the sizes of these atoms in scientific notation is 3.2 * 10^-11 m.
To find the difference between the sizes of these atoms in scientific notation, we need to subtract the size of the hydrogen atom from the size of the oxygen atom.
The size of the hydrogen atom is given as 1.2 * 10 ^ -10 m, and the size of the oxygen atom is given as 0.000000000152 m.
To subtract these two values, we need to convert the size of the oxygen atom to scientific notation. Since 0.000000000152 is equal to 1.52 * 10 ^ -10, the difference between the sizes of these atoms is:
(1.52 * 10 ^ -10) - (1.2 * 10 ^ -10)
Calculating this difference, we get:
0.32 * 10 ^ -10
This can be written in scientific notation as:
3.2 * 10 ^ -11 m
Therefore, the difference between the sizes of the hydrogen and oxygen atoms in scientific notation is 3.2 * 10 ^ -11 m.
To find the difference between the sizes of the hydrogen and oxygen atoms, we need to subtract the size of the hydrogen atom from the size of the oxygen atom.
First, let's convert the sizes of the atoms to scientific notation for easier calculation:
The size of a hydrogen atom is 1.2 * 10^-10 m.
The size of an oxygen atom is 1.52 * 10^-10 m.
Now, subtract the size of the hydrogen atom from the size of the oxygen atom:
1.52 * 10^-10 m - 1.2 * 10^-10 m = 0.32 * 10^-10 m
This can be simplified to:
0.32 * 10^-10 m = 3.2 * 10^-11 m
Therefore, the difference in sizes between these two atoms is 3.2 * 10^-11 m.
