PLEASE HELP DUE SOON
Alona [7]

Answer:

Because energy is conserved, the kinetic energy of a block at the bottom of a frictionless

ramp is equal to the gravitational potential energy of the block at the top of the ramp. This

value is proportional to the square of the block’s velocity at the bottom of the ramp.

Therefore, the block’s final velocity depends on the height of the ramp but not the steepness

of the ramp

For a particular reaction, Δ=−111.4 kJ and Δ=−25.0 J/K.
vichka [17]

Answer:

\Delta G =-103.95kJ

Explanation:

Hello there!

In this case, since the thermodynamic definition of the Gibbs free energy for a change process is:

\Delta G =\Delta H-T\Delta S

It is possible to plug in the given H, T and S with consistent units, to obtain the correct G as shown below:

\Delta G =-111.4kJ-(298K)(-25.0\frac{J}{K}*\frac{1kJ}{1000J} )\\\\\Delta G =-103.95kJ

Best regards!
