Answer: C2H6O

Explanation:

Empirical formula is the formula showing proportions of the elements present in a compound. Empirical formula will not show the arrangements of atoms in a compound.

From the question above, we are given that the compound contains 52.14% of carbon, 34.73% of oxygen and the amount of Hydrogen is unknown.

Therefore, to determine the amount of Hydrogen, we say;

100% of the whole compound - (52.14% + 34.73%).

Percentage of hydrogen in the compound= 13.13% .

Therefore, Mole of Hydrogen atom= 13.13/1 = 13.13.

Mole of carbon atom = 52.14/12= 4.345.

Mole of Oxygen atom= 34.73/16 = 2.171.

The next thing to do is to divide the each mole by the smallest mole(that is, the mole of oxygen atom).

Hence, Hydrogen,H = 13.13/2.171 =6.

Carbon,C= 4.345/2.171 = 2.

Oxygen = 2.171/2.171 = 1.

Therefore the empirical formula is;

C2H6O.

H %= 100- (52.14 + 34. 73) equals 13.13 %
Assuming 100 g of this compound
Mass H= 13.13 g
Moles H= 13.13 g ÷ 1.008g/ moles= 13

Mass C= 52.14 g
Moles C= 52.14 g ÷ 12.011 g/ moles= 4

The empirical formula is C4H1302

From goal line to goal line, a football field is 300 ft long. If a player catches the ball while standing on one goal line, runs
KATRIN_1 [288]

Answer:

The player ran 91.44m.

Explanation:

The problem gives you the total distance between goal line to goal line in feet, and the answer must be given in meters, so you should convert the distance the player run from ft to m, because the player run the same distance from goal line to goal line to scores the touchdown.

So, you should apply the following conversion factor:

300ft*\frac{0.3048m}{1ft}= 91.44m

The player ran 91.44m.

How to determine if a compound satisfies the octet rule?
Mumz [18]
You can determine this by counting the number of electrons on the last orbital. If the number of electrons on the last orbital (valence electrons) is 8 then it satisfies the octet rule because the compound has mirrored the look of a noble gass or “neutral” charge.

Describe the difference beetween an extensive and intesive property
olasank [31]

Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity.
