6. A student dissolved 1.1 g of solid NaOH in 22.1 mL of water inside a constant-pressure

Chemistry

8 0

From the calculations, the heat of the reaction is 44.4 kJ/mol.

<h3>What is the enthalpy of reaction?</h3>

The enthalpy of reaction refers to the amount of heat that is absorbed or evolved in a reaction.

Number of moles of NaOH = 1.1 g /40 g/mol = 0.0275 moles

Mass of the water = 22.1 mL or 22.1 g

Given that;

H= mcdT

H = 22.1 g *4.184 * (31.4 - 18.2)

H = 1221 J or 1.221kJ

ΔH rxn = -(1.221kJ)/0.0275 moles

ΔH rxn = 44.4 kJ/mol

What type of experiments can be carried out to determine the spontaneity of a reaction? Does spontaneity have any relationship t
Alexeev081 [22]

Answer:

Following are the responses to this question:

Explanation:

They can measure the spontaneity of the reaction with the form,\Delta G =\Delta H - T \Delta S Substituting the values of \Delta H, T,\ and \  \Delta S in the above expression information mostly on the playfulness of the reaction would be given to us from the expression above. This reaction is spontaneous if the price of \Delta G is negative, and if it is positive the response is not random. At equilibrium, the values of \Delta G, \Delta H, \ and \ \Delta S are 0.

3. give reasons
soldi70 [24.7K]

Answer:

A.A gas exerts pressure on the walls of the container. Reason: They have high kinetic energy and negligible force of attraction to move constantly moving with high speed in all directions. ... These collisions of the gas particles with the container walls exert pressure on the walls of the container.

B A gas exerts pressure on the walls of the container due to imapact of its gas molecules with hight velocity .

C.A wooden table should be called a solid. Reason: It has a definite shape and volume. It is very rigid and cannot be compressed, i.e., it has a solid characteristic.

D.We can easily move our hand in air but to do the same through a solid block of wood we need a karate expert. It is because the molecules of air has less force of attraction between them and a very small external force can separate them and pass through it.
