Answer:
bar one:constant acceleration
bar two:remains stationary
bar three:constant acceleration
Answer : The molar heat of solution for the salt is 452.9 kJ/mole
Explanation :
First we have to calculate the heat of solution.
where,
q = heat of solution = ?
c = specific heat of water = specific heat of solution =
m = mass of solution = 107.093 g
- Mass of solution = Mass of water + Mass of salt
- Mass of solution = 100.000 g + 7.093 g = 107.093 g
= change in temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the molar heat of solution for the salt, in kJ/mol.
where,
= molar heat of solution = ?
q = heat required = 8.456 kJ
m = mass of salt = 7.093 g
Molar mass of salt = 379.984 g/mol
Therefore, the molar heat of solution for the salt is 452.9 kJ/mole
Answer:
The net force acting on an object is proportional to the acceleration of that object with respect to an inertial frame of reference. The constant of proportionality in this, Newton's second law, is the classical mass of the object.
