Which of the following chemical reactions is an oxidation-reduction reaction?
3241004551 [841]
C. N₂ + 3H₂ → 2NH₃
In a redox, or oxidation-reduction, reaction, one of the reactants must be reduced, which means its oxidation number decreases, while the other reactant must be oxidized, which means its oxidation number increases. The oxidation number of nitrogen in the reactants is 0 and is -3 in the products, so it is reduced. Similarly, the oxidation number of hydrogen is 0 in the reactants but it is +1 in the products.

The air in a 4.00 L tank has a pressure of 1.20 atm . What is the final pressure, in atmospheres, when the air is placed in tank
stellarik [79]

Answer:

P₂ = 1.92 atm

Explanation:

According to the boyle's law:

The pressure of given amount of gas at constant temperature and number of moles of gas is inversely proportional to the volume.

P₁V₁= P₂V₂

Given data:

Initial volume = 4.00 L

Initial pressure = 1.20 atm

Final volume = 2500  mL  

Final pressure = ?

Solution:

First of all we will convert the volume into litter.

2500 mL × 1L/1000 mL = 2.5 L

P₁V₁ =  P₂V₂

P₂ = P₁V₁ /V₂

1.20 atm×4.00 L = P₂ ×2.5 L

P₂ = 1.20 atm×4.00 L/ 2.5 L

P₂ = 4.8 atm. L/ 2.5 L

P₂ = 1.92 atm
