If an ice skater with a mass of 50 kg was accelerating at 10 m/s and is on her way to hit a
IrinaK [193]

500N

Explanation:

Given parameters:

Mass of skater = 50kg

Acceleration = 10m/s

Unknown:

Force  = ?

Solution;

Force is a push or pull on a body. it is given as the product of mass and acceleration:

               Force = mass x acceleration

    Input the parameters:

                  Force = 50 x 10 = 500N

She hits the wall with a force of 500N

Measurements show that the enthalpy of a mixture of gaseous reactants decreases by during a certain chemical reaction, which is
snow_tiger [21]

The given question is incomplete. The complete question is as follows.

Measurements show that the enthalpy of a mixture of gaseous reactants decreases by 338 kJ during a certain chemical reaction, which is carried out at a constant pressure. Furthermore, by carefully monitoring the volume change it is determined that 187 kJ of work is done on the mixture during the reaction. Calculate the change in energy of the gas mixture during the reaction. Be sure your answer has the correct number of significant digits. Is the reaction exothermic or endothermic ?

Explanation:

The given data is as follows.

    Change in enthalpy (\Delta H) = -338 kJ (as it is a decrease)

    Work done = 187 kJ,

    Change in energy (\Delta E) = ?

Now, according to the first law of thermodynamics the formula is as follows.

          \Delta H = \Delta E + P \Delta V

Hence, putting the given values into the above formula as follows.

        \Delta H = \Delta E + P \Delta V

Also, we know that W = P \Delta V

so,           \Delta H = \Delta E + W      

              -338 kJ = \Delta E + 187

              \Delta E = -151 kJ

Thus, we can conclude that the change in energy of the gas mixture during the reaction is -151 kJ.
