The option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion

The correct answer choice is option c

In order words, kinetic energy is that type of energy which a body or an object posess due to its relative motion.

<h3>What is energy?</h3>

Energy can simply be defined as the capacity of doing work.

Energy is a derived quantity; meaning that it is obtained from the combination of fundamental quantities.

The unit of energy joules.

Other examples of derived quantities just like energy too are:

Volume
Speed
Acceleration
Density.
Upthrust
Momentum
Momentum
Power
Pressure
Force

Below are some few forms of energy; these are:

Kinetic energy
Potential energy
Mechanical energy
Solar energy
Light energy
Chemical energy

So therefore, the option which accurately defines kinetic energy from the choices above is:

the energy an object has because of its motion

Consider the following chemical equation: NH4NO3(s)⟶NH+4(aq)+NO−3(aq) What is the standard change in free energy in kJmol at 298

Galina-37 [17]

Answer:

$\Delta _rG=-4.3\frac{kJ}{mol}$

Explanation:

Hello,

In this case, for the given dissociation reaction, we can compute the enthalpy of reaction considering the enthalpy of formation of each involved species (products minus reactants):

$\Delta _rH=\Delta _fH_{NH^{4+}}+\Delta _fH_{NO_3^-}-\Delta _fH_{NH_4NO_3}\\\\\Delta _rH=-132.5+(-205.0)-(-365.6)=28.1kJ/mol$

Next, the entropy of reaction considering the standard entropy for each involved species (products minus reactants):

$\Delta _rS=S_{NH^{4+}}+S_{NO_3^-}-S_{NH_4NO_3}\\\\\Delta _rS=113.4+146.4-151.1=108.7J/mol*K$

Next, since the Gibbs free energy of reaction is computed in terms of both the enthalpy and entropy of reaction at the given temperature (298.15 K), we finally obtain (two significant figures):

$\Delta _rG=\Delta _rH-T\Delta _rS\\\\\Delta _rG=28.1kJ/mol-(298.15 K)(108.7\frac{J}{mol*K}*\frac{1kJ}{1000J} )\\\\\Delta _rG=-4.3\frac{kJ}{mol}$

Best regards.

Why is water said to be universal solvent?

Pachacha [2.7K]

Answer:

Explanation:

And, water is called the "universal solvent" because it dissolves more substances than any other liquid. This allows the water molecule to become attracted to many other different types of molecules.
