Answer:
85.5 mmHg is the pressure of the gas sample when the valve is opened.
Explanation:
The combined gas equation is,
where,
= initial pressure of gas in container A = 165 mmHg
= final pressure of gas = ?
= initial volume of gas in container A= 
= final volume of gas = 135 mL + 117 mL = 252 mL
= initial temperature of gas in container A = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
85.5 mmHg is the pressure of the gas sample when the valve is opened.

Explanation:
and that's bc it will not share stay the same
The pH value indicates the degree of acidity or alkalinity of a solution. In this case, the human body fluids. When the value is 0, the pH is acid, it is 14, we speak of an alkaline pH, and 7 indicates a neutral value. Inside the body, the pH may vary according to the body, and the specialists argue that do not have to be the same everywhere.
Answer: The object's heat of fusion is 68.52 Joules/gram.
Explanation:
Mass of the sample = 42 grams
Energy required to melt the sample completely = 2878 Joules
The object's heat of fusion is 68.52 Joules/gram.
