The size of a hydrogen atom is about 1.2x10^-10m across. The size of an oxygen atom is 0.000000000152m across. What is the difference between the sizes of these atoms in scientific notation?

The given size of a hydrogen atom is 1.2x10^-10 m, and the size of an oxygen atom is 0.000000000152 m.

To calculate the difference between the sizes of these atoms, we need to subtract the size of the hydrogen atom from the size of the oxygen atom.

Size of oxygen atom - Size of hydrogen atom = 0.000000000152 m - 1.2x10^-10 m

To make the subtraction easier, we need to convert 0.000000000152 m to scientific notation.

0.000000000152 m can be written as 1.52x10^-10 m in scientific notation.

Now, we can perform the subtraction:

1.52x10^-10 m - 1.2x10^-10 m = 0.32x10^-10 m

Since 0.32 is a whole number, we can simplify the expression further:

0.32x10^-10 m = 3.2x10^-11 m

Therefore, the difference between the sizes of these atoms is 3.2x10^-11 m.

To find the difference between the sizes of the hydrogen and oxygen atoms in scientific notation, we need to subtract the size of the hydrogen atom from the size of the oxygen atom.

The size of a hydrogen atom is 1.2x10^-10 m across, and the size of an oxygen atom is 0.000000000152 m across.

In scientific notation, the size of an oxygen atom is 1.52x10^-10 m across (since 0.000000000152 can be written as 1.52x10^-10).

Now, we can subtract the size of the hydrogen atom from the size of an oxygen atom:

1.52x10^-10 - 1.2x10^-10 = 0.32x10^-10 m

Finally, we can rewrite the answer in scientific notation:

0.32x10^-10 m = 3.2x10^-11 m

Therefore, the difference between the sizes of the hydrogen and oxygen atoms, in scientific notation, is 3.2x10^-11 m.

To find the difference between the sizes of these atoms in scientific notation, we need to subtract the smaller value from the larger value and express the result in scientific notation.

The size of a hydrogen atom is 1.2 x 10^-10 m.
The size of an oxygen atom is 1.52 x 10^-10 m.

To find the difference, we can subtract the size of the hydrogen atom from the size of the oxygen atom:

1.52 x 10^-10 m - 1.2 x 10^-10 m

To simplify the subtraction, we need to have the same power of 10 for both numbers. In this case, we can multiply 1.2 x 10^-10 m by 10 to make it 1.2 x 10^-9 m:

1.52 x 10^-10 m - 1.2 x 10^-9 m

Now that both numbers have the same power of 10, we can subtract them:

1.52 x 10^-10 m - 1.2 x 10^-9 m = -0.068 x 10^-9 m

Since the result is negative, we can convert it to positive by moving the decimal point one place to the right:

-0.068 x 10^-9 m = -6.8 x 10^-10 m

Therefore, the difference between the sizes of these atoms in scientific notation is -6.8 x 10^-10 m.
