empirical formula = when the percentage compositions by mass of elements in a compound are divided by their relative atomic masses.

from the obtained amount the smallest amount will divide all.

the answers can then be rounded off if in decimals or they can be multiplied by 2 if they have .5 decimals e.g 2.5 , 7.5 , etc.

solution: HYDROGEN    CARBON      OXYGEN

                2/1                      74/12               24/16

                  2                         6.167                 1.5

                  2 / 1.5                  6.167 / 1.5           1.5 / 1.5

                  1.333                        4.111                   1

                      1                              4                        1


answer :     C4OH

Solve for y in the following problem: 5.3 x 10- (y)(2y)
weqwewe [10]

Answer:

The value of y = 5.1478

Explanation:

The linear equation is an equation obtained when a linear polynomial is equated to zero. When the solution obtained on solving the equation is substituted in the equation in place of the unknown, the equation gets satisfied.

The given equation: 5.3 x 10- (y)(2y) = 0

⇒ 53 - 2y² = 0

⇒ 2y² = 53

⇒ y² = 53 ÷ 2 = 26.5

⇒ y = √26.5 = 5.1478

Answer:

Scientific Explanation of weather change and cause storms is described below in detail.

Explanation:

The weather is just the nature of the environment at any time, including items such as warmth, rainfall, air pressure, and cloud shelter. Daily variations in the weather are due to storms and winds. Seasonal variations are due to the Earth spinning nearby the sun. Warm beginnings often produce stormy weather as the heated air mass at the exterior rises above the cool air mass, creating clouds and storms.
