Answer : The enthalpy change for dissolving this salt on a energy per mass basis is 132.4 J/g
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water
where,
q = heat released by the reaction
= heat absorbed by the calorimeter
= heat absorbed by the water
= specific heat of calorimeter =
= specific heat of water =
= mass of water =
= change in temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy change for dissolving this salt on a energy per mass basis.
where,
= enthalpy change = ?
q = heat released = 331.08 J
m = mass of salt = 2.50 g
Therefore, the enthalpy change for dissolving this salt on a energy per mass basis is 132.4 J/g
Answer:
They learned because they keeped studying they would never give up and if they found something new or interesting they may have just studied it more.

Answer:
It takes 2 hours for a police car to travel a distance of 29 miles with 58 miles per hour.
Explanation:
The speed of the car is 58 miles per hour.
The total distance traveled is 29 miles.
We need to find the time taken to cover the distance of 29 miles by the police car if police traveled at 58 miles per hour.
We know that,
Relationship between speed, time and distance is
Now substitute the given values in the above formula,
Time = 2 hours.
