Answer:

All options apply

Explanation:

Take for example the following oxidation-reduction reaction:

2 H2  + O2   -> 2 H2O  

Hydrogen is oxidized, then its oxidation number increased (from 0 to +1) and lost electrons.

On the other hand, oxygen is reduced,  that is, its oxidation number decreased (from 0 to -2) and gain the electrons lost by hydrogen.

How much pressure would 0.8 moles of a gas at 370K exert if it occupied 17.3L of space
dezoksy [38]

Answer:

1.40 atm is the pressure for the gas

Explanation:

An easy problem to solve with the Ideal Gases Law:

P . V = n . R .T

T° = 370K

V = 17.3L

n = 0.8 mol

Let's replace data → P . 17.3L = 0.8mol . 0.082L.atm/mol.K . 370K

P = (0.8mol . 0.082L.atm/mol.K . 370K) / 17.3L = 1.40 atm
