Answer:
1, mass is like how big it appears and weight could be small and be more weight then something with alot of mass
2, sorry i dont know
3, Jupiter you would weigh the most and the least is mars
4, the sun and if it was changed all the plants would eventually collide and go out of order
5, gravity, electricity and magnetism
Explanation:
Answer:
The final temperature of the solution is 46.93°C
Explanation:
we have to calculate the heat produced.
where,
= enthalpy change = 81.5 kJ/mol
q = heat released = ?
m = mass of CaCl_2 = 15.0 g
Molar mass of CaCl_2 = 110.98 g/mol
Now put all the given values in the above formula, we get:
calculate the final temperature of solution in the calorimeter.
where,
q = heat produced = 11.0 kJ = 11000 J
m = mass of solution = 15.0 + 105 = 120.0 g
c = specific heat capacity of water = 4.18J/g°C
= initial temperature = 25.0°C
= final temperature = ?
Now put all the given values in the above formula, we get:
The final temperature of the solution is 46.93°C
Answer:
C
