Answer: the heat content of a system at constant pressure.
Explanation:
Enthalpy is defined as the heat content of a system at constant pressure.
It is the heat absorbed or released during a reaction at constant pressure,denoted as ΔH.
Answer:
see explanation below
Explanation:
The question is incomplete. The missing parts are a) determine the electrophylic site. b) determine the nucleophylic site.
In order to do this, we need to write the reaction and do the mechanism. The nucleophylic site will be the site where the nucleophyle attacks to form the product. In this case the site is the carbon next to the bromine. In this place the Oxigen which is the nucleophyle goes. The electrophyle is the site where one atom substract to complete it's charges. In this case, the electrophyle is usually the hydrogen, so the site will be next to the oxygen after the nucleophyle attack.
You can see it better in the attached picture.
Answer:
40 atm.
Explanation:
From the question given above, the following data were obtained:
Initial volume (V₁) = 200 mL
Initial pressure (P₁) = 2 atm
Final volume (V₂) = 10 mL
Temperature = constant
Final pressure (P₂) =?
The final pressure of the gas can be obtained by using the Boyle's law equation as shown below:
P₁V₁ = P₂V₂
2 × 200 = P₂ × 10
400 = P₂ × 10
Divide both side by 10
P₂ = 400 / 10
P₂ = 40 atm
Thus, the final pressure of the gas is 40 atm.
