The force of gravity gets stronger.
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 options are not orderly written but the correct answer is :
All of the above.
Explanation:
Glucagon and insulin are peptide hormones secreted by pancreas which plays a major role in maintaining a stable blood glucose level. Glucagon is generated by alpha cells in the pancreas and acts to raise blood sugar levels. Insulin is generated by beta cells in the pancreas and acts to lower blood sugar levels.
Catalysts are used in the oil industry to increase octane
ratings in gasoline. Octane ratings tell how much fuel has to be compressed to
promote better fuel ignition in some
cars. The catalytic effect that
would be most beneficial for the oil industry is that more products can be
formed from a given amount of material.
