What are the symbols, atomic mass and abundance in nature of the isotope boron-11
Aneli [31]
  1. The chemical symbol of the isotope boron-11 is ¹¹B.
  2. The atomic mass of the isotope boron-11 is equal to 11.009306.
  3. The abundance in nature of the isotope boron-11 is equal to 80.1%.

<h3>What is an isotope?</h3>

An isotope can be defined as the atom of a chemical element that has the same number of protons but different number of neutrons. This ultimately implies that, the isotopes of an element have the same atomic number (number of protons) but different atomic mass (number of neutrons).

In Chemistry, there are two main isotopes of boron and these include the following:

  • Boron-10
  • Boron-11

Boron-11 is the most stable isotope of boron and it is characterized by the following:

  1. The chemical symbol of the isotope boron-11 is ¹¹B.
  2. The atomic mass of the isotope boron-11 is equal to 11.009306.
  3. The abundance in nature of the isotope boron-11 is equal to 80.1%.

A student observed a blue
morpeh [17]

Answer:

Color.

Explanation:

Hello,

In this case, since matter has a lot of properties regarding its physical condition and chemical composition, those related to the appearance of matter are physical. In such a way, since the student observed to different substances with also different colors, we can infer that the property of matter that was observed in the scenario was color, which accounts for the graphical perception we have from them.

Best regards.

Aluminum chloride, AlCl3, is an inexpensive reagent used in many industrial processes. It is made by treating scrap aluminum wit
mylen [45]

Answer:

83.8%

Explanation:

The balanced reaction equation is;

2Al(s) + 3Cl2(g) → 2AlCl3(s)

Now we have to obtain the limiting reactant as the reactant that produces the least amount of AlCl3

Amount of Al = 3.11g/27 g/mol = 0.115 moles

If 2 moles of Al yields 2 moles of  AlCl3

Then 0.115 moles of Al yields 0.115 moles of  AlCl3

For Cl2

Amount of Cl2 = 5.32 g/71 g/mol= 0.075 moles

If 3 moles of Cl2 yields 2 moles of  AlCl3

0.075 moles of Cl2 yields 0.075   * 2/3 = 0.05 moles of  AlCl3

Hence Cl2 is the limiting reactant

Theoretical yield of  AlCl3 = 0.05 moles of  AlCl3 * 133g/mol = 6.65 g

%yield = actual yield /theoretical yield * 100

%yield = 5.57 g/6.65 g * 100

%yield = 83.8%
