If 5.60 mol of a substance releases 14.9 kJ when it decomposes, what is ΔH for the process in terms of kJ/mol of reactant?

The correct approach is "-2.67 kJ/mole". A further solution is described below.

Explanation:

The given values are:

No. of moles,

= 5.60 mol

Substance releases,

ΔH = 14.9 kJ

Now,

The ΔH in terms of kJ/mol will be:

=

On putting the given values of ΔH, we get

=

=

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
