A peregrine falcon dives 176 meters through the air in 8 seconds. Its
CaHeK987 [17]

Answer:

This question is asking to find the average speed during the dive. The answer is 22m/s.

Explanation:

Average speed of a substance can be calculated knowing it's distance over a particular amount of time.

The formula for average speed is:

Average speed (s) = Distance (d) / time (t)

In the case of this question where A peregrine falcon dives 176 meters through the air in 8 seconds, the distance of the falcon is 176m, while the time is 8s. Hence;

Average speed = 176/8

Average speed = 22

Therefore, the average speed of the falcon diver is 22m/s.

We can also use the equation for enthalpy change for physical phase changes. Consider the phase change H2O(l) → H2O(g). Calculat
VLD [36.1K]

Answer: The value of enthalpy of the given reaction is 44.000 kJ/mol , that is energy is supplied to water to change into water vapors

Explanation:

H_2O(l)\rightarrow H_2O(g),\Delta H_{rxn}=?

Enthalpy of formation of water in liquid state,\Delta H_{f,H_2O(l)}=-285.820 kJ/mol

Enthalpy of formation of water in gaseous state,\Delta H_{f,H_2O(g)}=-241.820 kJ/mol

\Delta H_{rxn}=\sum \Delta H_f \text{of products}-\sum \Delta H_f \text{of reactants}

\Delta H_{rxn}=(-241.820 kJ/mol)-(-285.820 kJ/mol)=44.000 kJ/mol

The value of enthalpy of the given reaction is 44.000 kJ/mol, that is energy is supplied to water to change into water vapors.
