Need help with this question.... Next to each Formula, write the number of atoms of each element found in one unit of the compou
Andrew [12]

Answer:

The number of atoms present in one unit of the following compounds is:

a). Potassium Iodide , KI = 2

b).Sodium Sulfide, Na_{2}S = 3

c). Silicon Dioxide , SiO_{2} = 3

d). Carbonic Acid ,H_{2}CO_{3} = 6

Explanation:

Atomicity : It is defined as the number of atoms that are present in a given molecule/compound.

Atom : The smallest unit of matter is called atom. For e.g O is atom of oxygen but O_{2} is not an atom , it is molecule of oxygen .

O_{2} molecule has 2 atoms of Oxygen

Similarly  Na , K , Fe are atoms but O_{2} ,CO_{2} ,N_{2},H_{2}  are molecules

a).Potassium Iodide

KI = 1 atom of K + 1 atom of I

Total atoms = 2

b) Sodium Sulfide

Na_{2}S = 2 atoms of Na + 1 atom of S

Total atoms = 3

c) Silicon Dioxide

SiO_{2} = 1 atom of Si + 2 atoms of O

Total atoms = 3

d) Carbonic Acid

H_{2}CO_{3} = 2 atom of H + 1 atom of C + 3 atom of O

= 2+1+3

Total atoms = 6

What are some ways that organelles are similar to organ system?
Vaselesa [24]

Explanation:

Like organs in an organism, each organelle has a specific function in a cell. All of the organelles work together to carry out the functions of the cell as a whole, just as organs do to an organism. For example, mitochondria are the sites of cellular respiration; they provide energy the cell
