Answer:
42.24 psi.
Explanation:
From the question given above, the following data were obtained:
Initial pressure (P₁) = 29.72 psi
Initial volume (V₁) = 10.22 L
Final volume (V₂) = 7.19 L
Final pressure (P₂) =?
The final pressure can be obtained by applying the Boyle's law equation as follow:
P₁V₁ = P₂V₂
29.72 × 10.22 = P₂ × 7.19
303.7384 = P₂ × 7.19
Divide both side by 7.19
P₂ = 303.7384 / 7.19
P₂ = 42.24 psi
Therefore, the final pressure is 42.24 psi
The answer is D because the air is made of nitrogen and oxygen. The reaction is endothermic.
Hope this helps you! :)
Answer:
double replacement reaction or double displacement reaction,
Explanation:
double replacement reaction, double displacement reaction, is a chemical process involving the exchange of bonds between two non-reacting chemical species which results in the creation of products with similar or identical bonding affiliations
Classically, these reactions result in the precipitation of one product.
in thía case it is AgCl
Answer:
2726.85 °C
Explanation:
Given data:
Initial pressure = 565 torr
Initial temperature = 27°C
Final temperature = ?
Final pressure = 5650 torr
Solution:
Initial temperature = 27°C (27+273 = 300 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
T₂ = P₂T₁ /P₁
T₂ = 5650 torr × 300 K / 565 torr
T₂ = 1695000 torr. K /565 torr
T₂
= 3000 K
Kelvin to degree Celsius:
3000 K - 273.15 = 2726.85 °C
