An asteroid is not considered a moon because it is a rock that floats in space and sometimes gravity pulls it in a different direction.
Answer:
The enthalpy change during the reaction is -199. kJ/mol.
Explanation:
Mass of solution = m
Volume of solution = 100.0 mL
Density of solution = d = 1.00 g/mL
First we have to calculate the heat gained by the solution in coffee-cup calorimeter.
where,
m = mass of solution = 100 g
q = heat gained = ?
c = specific heat =
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy change during the reaction.
where,
= enthalpy change = ?
q = heat gained = 2.242 kJ
n = number of moles fructose =
Therefore, the enthalpy change during the reaction is -199. kJ/mol.
Answer is: <span>5. one pair of electrons and two lone electrons.
Electron configuration for carbon: </span>₆C 1s² 2s² 2p².
Valence electrons are in 2s and 2p orbitals. There is one pair of electrons in 2s orbital and two lone electrons in 2p orbital with the same electron spin. Carbon is in group 14 of periodic table group.
