Answer : The final volume of gas will be, 26.3 mL
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 0.974 atm
= final pressure of gas = 0.993 atm
= initial volume of gas = 27.5 mL
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
Therefore, the final volume of gas will be, 26.3 mL
Answer:
endothermic reaction
Explantion:
The definition for endothermic is:
describing a process that involves the absorption of energy from the surroundings by substances undergoing change.
Think of <em>en-</em>dothermic as energy entering and <em>ex-</em>othermic as energy exiting.
