You analyze two substances in the laboratory and discover that each has the empirical formula CH2O. You can easily see that they
Anna007 [38]

Explanation:

Molecular formulas is the actual number of atoms of each element in the compound while empirical formulas is the simplest or reduced ratio of the elements in the compound.

Thus,

Molecular mass = n × Empirical mass

The empirical formula is CH_2O

The two substances are differed by their physical properties.

These properties match with :

C_3H_6O_3 in which n =3 is molecular formula for lactic acid. Lactic acid is exists in liquid state and have a biting order.

C_6H_{12}O_6 in which n =6 is molecular formula for glucose. Glucose is exists in crystalline solid form and is odorless.

Using standard reduction potentials from the ALEKS Data tab, calculate the standard reaction free energy for the following redox
stealth61 [152]

Answer:

-973 KJ

Explanation:

The balanced reaction equation is;

N2H4(aq) + 2Cl2(g) + 4OH^-(aq)---------> 4Cl-(aq) + 4H ^+(aq) + 4OH^-(aq) + N2(g)

Reduction potential of hydrazine = -1.16 V

Reduction potential of chlorine = 1.36 V

From;

E°cell= E°cathode - E°anode

E°cell= 1.36 - (-1.16)

E°cell= 2.52 V

∆G°=- nFE°cell

n= number of moles of electrons = 4

F= Faraday's constant = 96500 C

E°cell = 2.52 V

∆G°=- (4 × 96500 × 2.52)

∆G°= -972720 J

∆G°= -972.72 KJ
