Determine the empirical formulas for the following compounds:

zysi [14]

Explanation:

Empirical formula is defined as the formula in which atoms in a compound are present in simplest whole number ratios.

For the given options:

Option a: Acetic acid

Acetic acid having molecular formula $C_2H_4O_2$ . To write the empirical formula, we divide each subscript by 2.

$C_{2/2}H_{4/2}O_{2/2}=CH_2O$

Hence, the empirical formula for acetic acid is $CH_2O$

Option b: Citric acid

Citric acid having molecular formula $C_6H_8O_7$ . To write the empirical formula, we divide each subscript by 1.

$C_{6/1}H_{8/1}O_{7/1}=C_6H_8O_7$

Hence, the empirical formula for citric acid is $C_6H_8O_7$

Option c: Hydrazine

Hydrazine having molecular formula $N_2H_4$ . To write the empirical formula, we divide each subscript by 2.

$N_{2/2}H_{4/2}=NH_2$

Hence, the empirical formula for hydrazine is $NH_2$

Option d: Nicotine

Nicotine having molecular formula $C_{10}H_{14}N_2$ . To write the empirical formula, we divide each subscript by 2.

$C_{10/2}H_{14/2}N_{2/1}=C_5H_7N$

Hence, the empirical formula for nicotine is $C_5H_7N$

Option e: Butane

Butane having molecular formula $C_{4}H_{10}$ . To write the empirical formula, we divide each subscript by 2.

$C_{4/2}H_{10/2}=C_2H_5$

Hence, the empirical formula for butane is $C_2H_5$

PLEASE HELP QUICKLY! SERIOUS ANSWER PLEASE

yarga [219]

Answer:

Q1: A

Q2: B

Explanation:

Q1: the independent variable will always go on the x axis and the dependent will always go on the y-axis, so the answer is A.

Q2: it's not a, it's not d (ocean droughts aren't a thing that I'm aware of), and hurricanes don't make water scarce, so I would go with B.

Isomers have the same physical properties because the chemical formulas are identical. True False

Luda [366]

The statement is False.
The molecular (chemical) formulas are same in case of isomers but the arrangement of atoms is different in them. The physical properties are determined by the arrangement of atoms within the molecule.

Since the arrangement of atoms is different in case of isomers, the Physical Properties will also be different.
