A calorimeter holds 45 g water at 22.0°C. A sample of hot iron is added to the water, and the final temperature of the water and iron is 28.0°C. What is the change in enthralling associated with the change in the water’s temperature?

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
