Is the number of hydrogen atoms a function of the number of oxygen atoms? Explain

To count atoms in a molecule, add the subscripts of the molecule. Remember that if you do not see a subscript after a symbol, its subscript is 1. One molecule of water contains 3 atoms.

Step-by-step explanation:

The molecular formula for water is

H

2

O

, meaning there are 2 hydrogen atoms and one oxygen atom. I found this by adding the subscripts. 2 is the subscript on hydrogen, and 1 is the subscript on oxygen, so 2 + 1 = 3 atoms total.

For example, to count the number of atoms in one molecule of glucose,

C

6

H

12

O

6

, add the subscripts, so 6+12+6 is 24 atoms. Note that

C

6

H

12

O

6

is the molecular formula of glucose, not the empirical formula.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46
