A thermometer is placed in water in order to measure the water’s temperature. What would cause the liquid in the thermometer to

rise?
The molecules in the water move closer together.

The molecules in the thermometer’s liquid spread apart.

The kinetic energy of the water molecules decreases.

The kinetic energy of the thermometer’s liquid molecules decreases

I believe the correct answer from the choices listed above is the second option. It would be that the molecules in the thermometer’s liquid spread apart that caused <span>the liquid in the thermometer to rise. The heat expanded the liquid inside. Hope this answers the question.</span>

Answer: Option (b) is the correct answer.

Explanation:

When we use a thermometer to measure the temperature of water then heat from the water will lead to represent an increase in the thermometer reading.

This is because heat or warmth from the water will get transferred to the thermometer as a result, the liquid in the thermometer will also get warm.

Therefore, this warmth will increase kinetic energy of the molecules of liquid in the thermometer. Hence, the liquid will spread.

Thus, we can conclude that the liquid in the thermometer to rise because  molecules in the thermometer’s liquid spread apart.

Given that a chlorine-oxygen bond has an enthalpy of 243 kJ/mol , an oxygen-oxygen bond has an enthalpy of 498 kJ/mol , and the
Alecsey [184]

Explanation:

The chemical equation is as follows.

      \frac{1}{2}Cl_{2}(g) + \frac{1}{2}O_{2}(g) \rightarrow ClO(g)

And, the given enthalpy is as follows.

    \frac{1}{2}Cl_{2}(g) + O_{2}(g) \rightarrow ClO_{2}(g);  \Delta H = 102.5 kJ

    Cl-Cl = 243 kJ/mol,      O=O = 498 kJ/mol

Since, the bond enthalpy of Cl-Cl is not given so at first, we will calculate the value of Cl-Cl as follows.

   \Delta H = \sum \text{bond broken in reactants} - \sum \text{bond broken in products}

    102.5 = [(\frac{1}{2})x + 498] - [(2)(243)]

    102.5 = (\frac{1}{2})x + 498 - 486

     102.5 - 12 = \frac{x}{2}

           x = 181 kJ

Now, total bond enthalpy of per mole of ClO is calculated as follows.

       \Delta H = \sum E(\text{bond broken in reactants}) - \sum (\text{bond broken in products})

              x = [(\frac{1}{2})181 + (\frac{1}{2})498] - 243

                 = 339.5 - 243

                 = 96.5 kJ

Thus, we can conclude that the value for the enthalpy of formation per mole of ClO(g) is 96.5 kJ.

What is pressure in relation to a gas?
labwork [276]

The pressure of a gas is the force that a gas exerts per unit area of the container.

Pressure is defined as force per unit area. Gas molecules are constantly colliding against the walls of the container. The pressure of the gas is the force the gas is exerting on its container.

Since temperature is defined as the average kinetic energy of the molecules of a gas then the higher the temperature, the faster the particles move.

The volume of a container refers the size if the container.

The pressure of a gas is inversely proportional to its volume according to Boyle's law. Thus implies that if the pressure of the gas goes up, the volume has to go down.

For a compound to be called an acid, it must contain H+ and H3O+ when dissolved in water.

For a compound to be called a base, the compound must dissolve in water to yield hydroxide ions.
