Write the complete balanced equation for the following reaction:
Assoli18 [71]

Explanation:

An equation that consists of same number of atoms on both reactant and product side is known as a balanced chemical equation.

For example, C_{7}H_{6}O + O_{2} \rightarrow CO_{2} + H_{2}O

Number of atoms on reactant side are as follows.

C = 7

H = 6

O = 3

Number of atoms on product side are as follows.

C = 1

H = 2

O = 3

Therefore, to balance this chemical equation we multiply O_{2} by 8 on reactant side. Whereas we multiply CO_{2} by 7 and H_{2}O by 3 on product side.

Therefore, the balanced chemical equation will be as follows.

          C_{7}H_{6}O + 8O_{2} \rightarrow 7CO_{2} + 3H_{2}O

Answer:

Skeletal system

Explanation:

The skeletal system is made up of all the bones, cartilage, and ligaments in the body. There are over 200 bones in the human skeleton, connected by joints which allow them to bend and rotate.

It protects the vital organs, gives our body form and structure, and allows us to move (or bust a move!)

To move, the skeletal system works with the muscles and nerves in the body.

You take a balloon and stick it in a refrigerator. The temperature inside the refrigerator is 4.0 °C and the temperature in your
Kobotan [32]
 First convert the 2 temperatures to  degrees K:
4   + 273  ---> 277   and 22---> 295

So using Charles' Law

V1 / T1  = V2 / T2
0.50 / 295 = V2 / 277

solving for V2 gives a volume of  0.469 L  to nearest milliliter
