Franklin was performing an experiment by combining hydrochloric acid and sodium hydroxide. He measured the mass of his reactant

materials to be 35g. The reaction resulted in the production of salt and water. He reported that his products weighed 32g.

Answer:

<u></u>

  • <u><em>B) an error occurred, the mass of the reactants should equal the mass of the products. </em></u>

<u><em /></u>

Explanation:

The answer choices are:

  • <em>A) no error occurred, some of the products are always lost as heat.</em>

<em />

  • <em>B) an error occurred, the mass of the reactants should equal the mass of the products. </em>

<em />

  • <em>C) an error occurred, the products should weigh more than the reactants. </em>

<em />

  • <em>D) no error occurred, water is not weighed when determining the weight of the products.</em>

<h2>Solution</h2>

The basis to answer this question is the law of conservation of mass.

Any chemical reaction satisfies the law of conservation of mass: mass cannot be either created nor destroyed, so, always, <em>the mass of the reactants equal the mass of the products.</em>

Thus, since he measured the mass of his reactant materials to be 35g and he reported that his products weighed 32g, his data are in clear contradiction of the law of conservation of mass. So, there is an error in his results: <em>the mass of the reactants should equal the mass of the products. </em>

D. Even though the temperature is the same, container B has more thermal energy, since it has more liquid than container A.

<u>Explanation: </u>

Whenever there is an increase in the volume of the pink liquid, it is due to the increase in temperature.

When the temperature increases, the molecules move farther apart as much as possible.

When the molecules moves apart from each other and collide with each other, so that its kinetic energy also increases, So thermal energy of the container B is more compared to the container A.

The table shows the average distance between the molecules of a substance in the solid, liquid, and gaseous states.
Pavlova-9 [17]

Answer:

Y > X > Z

Explanation:

The intermoecular forces refer to forces that exist between molecules of a substance. They are the secondary bond forces that hold particles of a substance together in a particular state of matter.

The shorter the distance between molecules, the greater the magnitude of intermolecular force between the molecules.

The molecules of Y are at the shortest distance from each other hence they have the highest magnitude of intermolecular forces. Followed by X and lastly Z with the greatest distance between the largest intermolecular distance.

Boyles Law P1V1 = P2V2
arsen [322]

Answer:

A. The balloons will increase to twice their original volume.

Explanation:

Boyle's law states that the pressure exerted on a gas is inversely proportional to the volume occupied by the gas at constant temperature. That is:

P ∝ 1/V

P = k/V

PV = k (constant)

P = pressure, V = volume.

P_1V_1=P_2V_2

Let the initial pressure of the balloon be P, i.e. P_1=P, initial volume be V, i.e. V_1=V. The pressure is then halved, i.e. P_2=\frac{P}{2}

P_1V_1=P_2V_2\\\\P*V=\frac{P}{2} *V_2\\\\V_2=\frac{2*P*V}{P}\\\\V_2=2V

Therefore the balloon volume will increase to twice their original volume.
