Answer:

The atomic number of Carbon is 6

Explanation:

Atomic number means the number of protons in the nucleus of an atom. Carbon has 6 protons in the nucleus and therefor its atomic number is 6. In the periodic table the atomic number is usually found on the top right corner of each element. Carbon is also located in the group 14 (also known as group IVA) and in period 2.

Jesse notices that his gas mileage jumps from 20 to 40 per gallon when he uses his cruise control. One likely explanation for th

stich3 [128]

<h3><u>Answer;</u></h3>

D. jesse's car is a hybrid that shuts off extra pistons when it is not accelerating

<h3><u>Explanation;</u></h3>

When cruising, hybrid cars are able to employ electrical energy to drive the car.
Moreover, even if a vehicle is not a hybrid, a greater amount of fuel is consumed when one accelerates because the vehicle has to generate a force larger than the force of air resistance in order for it to accelerate.
This increased demand of force reduces the vehicle's fuel economy.

Example #1 write the chemical formula for Calcium Oxide

Step 1

-Find the Atomic symbol of the metal and non-metal on the periodic table

CaO

Step 2

Find the charges for Calcium and Oxygen

which are Ca 2+ and O 2-

Step 3

Balance out the charges

They are already balanced out

Here´s the chemical formula for Calcium Oxide

CaO

Example 2 write the chemical formula for Aluminum Oxide

Step 1

-Find the Atomic symbol of the metal and non-metal on the periodic table

Step 2

Find the charges for Aluminum and Oxygen

Which are Al 3+ and O 2-

Step 3

Balance out the charges

You need 2 Aluminum and 3 Oxygen to balance the charges

Al 3+ O 2-

= 6 + O 2-

= 6-

Step 4

If you need more then one element to balance out the charges you identify that by using subscripts

Heres your chemical formula for Aluminum Oxide

$Al_{2} O_{3}$
