Chemistry
1 answer:
Alchen [17]3 years ago
7 0

Answer:

T₂  = 84.375 K

Explanation:

Given data:

Initial volume = 3.3 L

Initial pressure = 2000 torr

Initial temperature = 225 K

Final temperature = ?

Final volume = 2.75 L

Final pressure = 900 torr

Formula:

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

P₁V₁/T₁ = P₂V₂/T₂  

T₂  = P₂V₂ T₁ /P₁V₁

T₂  = 900 torr× 2.75 L× 225 K / 2000 torr×3.3 L

T₂  = 556875 K/ 6600

T₂  = 84.375 K

The volume of a gas is increased from 445mL to 515ml. If the initial pressure was 120kPa, what is the final pressure of the gas?
Hoochie [10]

Answer: 103.7 kPa

Explanation:

Given that:

initial volume of gas V1 = 445ml

initial pressure of gas P1 = 120 kPa.

new Volume V2 = 515ml

new pressure P2 = ?

Since, only pressure and volume are involved, apply the formula for Boyle's law

P1V1 = P2V2

120 kPa x 445ml = P2 x 515 kPa

53400 = P2 x 515 kPa

P2 = 53400/515

P2 = 103.7 kPa

Thus, the final pressure of the gas is 103.7 kPa

How can alcohol content be increased
konstantin123 [22]

Answer:

Alcohol is a byproduct of the fermentation process, which takes place when the yeast converts the sugars derived from the grain. Knowing that, you can increase the alcohol by volume (ABV) by increasing the size of the grain bill or increasing the amount of malt extract used.

Which of the following best describes a pair of elements that will form an ionic bond?
baherus [9]
An ionic bond forms between a metal and a nonmetal. So, since C and O are nonmetals it cannot be that one. Also, P and Cl are also both nonmetals so it cannot be that one either. That leaves Li and O and Ca and Br. In an ionic bond metals loose electrons and nonmetals gain electrons. Therefore it cannot be Li and O because it states that oxygen, the nonmetal, looses electrons and lithium, the metal, looses electrons. So, the answer has to be Ca and Br because Ca, the metal, looses electrons and Br, the nonmetal, gains electrons.
