Using the balanced equation given below, calculate the number of moles of CaBr2 produced in the reaction of 5.0 moles of AlBr3.

allochka39001 [22]

Answer:

7.5 moles of CaBr2 are produced

Explanation:

Based on the equation:

2AlBr3 + 3CaO → Al2O3 + 3CaBr2

2 moles of AlBr3 produce 3 moles of CaBr2 if CaO is in excess.

Using this ratio: 2 moles AlBr3 / 3 moles CaBr2. 5 moles of AlBr3 produce:

5 moles AlBr3 * (3 moles CaBr2 / 2 moles AlBr3) =

<h3>7.5 moles of CaBr2 are produced</h3>

Which of the following statements about the kinetic molecular theory are not correct?

Rashid [163]

Answer:

The false statement is: (C) The average kinetic energy of the molecules is not related to the absolute temperature

Explanation:

According to the Kinetic Theory of Gases, gases are composed of small fast moving particles that are in constant random motion. These gaseous particles are known as molecules.

It is assumed that the mass of all the gaseous molecules is the same and the intermolecular interactions (attractive or repulsive) are negligible.

Also, the total volume of all the gaseous molecules is considered to be negligible as compared to the volume of the container.

According to this theory, average kinetic energy (K) of the gaseous particles is directly proportional to the absolute temperature (T) of the gas, by the equation:

$K = \frac{3}{2}k_{b}T$

Here, $k_{b}$ is the Boltzmann constant

Therefore, the false statement about the kinetic molecular theory is (C)

kakasveta [241]

Answer:

by repeating the experiment several times

Explanation:

A scientist conducted one trial of an experiment and got unexpected results. Therefore, he should repeat his experiment and see if he is getting the same result again or not. If the result is again the same and does not matches his expectations then he should discuss the results with other scientist. If the result is different, then he should check for the cause of error.
