If you have a 100g of Boron and you want to find out how

many molecules of Boron you have, you would need to...

Answers

Answer:

5.57 x 10^24 atoms

Explanation:

first, you are seeking the number of ATOMS of Boron.

Boron has an Atomic mass of 10.8 g/mol (see #5 on the periodic table)

100 gm of Boron would have 100 g /10.8 g/mol =9.26 moles

each mole has Avogadros number of atoms 6.02 x 10^23

9.26 moles has 9.26 x 6.02 x 10^23 atoms =5.57 x 10^24 atoms

the proton concentrations of three solutions at 25 °c are given. classify the solutions as acidic, basic, or neutral.

Answers

This problem is giving information about the proton concentrations of three solutions at 25 °C. Despite they are not numerically given, we can propose three scenarios to see how to approach the question.

Let the following solutions to come up:

[H⁺] = 2.63x10⁻³ M

[H⁺] = 1.00x10⁻⁷ M

[H⁺] = 4.511x10⁻⁹ M

The first step, will be the calculation of the pH for each solution via:

pH = -log([H⁺])

So that they turn out to be:

pH = -log(2.63x10⁻³ M) = 2.580

pH = -log(1.00x10⁻⁷ M) = 7.000

pH = -log(4.511x10⁻⁹ M) = 8.3457

In such a way, since acidic solutions have a pH below 7, neutral have a pH equal to 7 and basic have it above 7, we infer the first one is acidic, second one is neutral and third one is basic.

Thus, you can reproduce this methodology with the proton concentrations you are given.

2. Choose the atom from each of the following pairs with the greater ionization energy: a. Be and Ba b. Al and Ar c. Ca and Cl

Answers

Considering the definition of ionization energy, the highest ionization energy belongs to the element:

a. Be

b. Ar

c. Cl

Electrons are held in atoms by their attraction to the nucleus, which means that energy is needed to remove an electron from the atom.

You should keep in mind that the electrons of the last layer are always lost, because they are the weakest attracted to the nucleus.

Ionization energy, also called ionization potential, is the necessary energy that must be supplied to a neutral, gaseous, ground-state atom to remove an electron from an atom. When an electron is removed from a neutral atom, a cation with a charge equal to +1 is formed.

In a group, the ionization energy increases upwards because when passing from one element to the bottom, it contains one more layer of electrons. Therefore, the valence layer electrons, being further away from the nucleus, will be less attracted to it and it will cost less energy to pluck them.

In the same period, in general, it increases as you shift to the right. This is because the elements in this way have a tendency to gain electrons and therefore it will cost much more to tear them off than those on the left which, having few electrons in the last layer will cost them much less to lose them.

Considering all the above, from each of the pairs, the highest ionization energy belongs to the element:

a. Be

b. Ar

c. Cl

what aspects are not accounted for in the ideal gas law?

Answers

The aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.

In the ideal gas law, it it assumed that the molecules of the gas are so far away from each other and thus they do not exert a significant force of attraction on each other. Also, the volume of each molecule of gas is neglected and assumed negligible and thus does not account for the overall volume of the gas.

So, the aspects not accounted for in the ideal gas law are the force of attraction of the gas molecules on each other and the volume of the gas molecules.

0.0200 moles of a compound is found to have a mass of 1.64 g. Find the formula mass of the compound
Give your answers to 3 significant figures

Answers

Answer: 82.0 g/mole

Explanation:

Use the units to see that if we divide 1.64 grams by 0.0200 moles, we'll get a number that is grams/mole, the definition of formula mass.

1.64/0.0200 = 82.0 g/mole (3 sig figs)

We can't tell from this alone what the molecular formula might be, but C6H10 (cyclohexene) comes close (82.1 grams/mole).

The formula mass of the compound will be approximately 82.0 g/mol

The formula mass of the compound is the sum of atomic masses of all the atoms in its chemical formula. It is calculated by adding up the atomic masses of the individual elements in the compound, each multiplied by the subscript indicating the number of atoms of that element in the formula.

To find the formula mass of the compound, we'll use the relationship between moles, mass, and molar mass.

Molar mass (in g/mol) = Mass (in g)/Moles

Given:

Mass = 1.64 g

Moles = 0.0200 moles

Let's plug the values and calculate molar mass:

Molar mass = 1.64 g / 0.0200 moles

Molar mass ≈ 82.0 g/mol

The formula mass of the compound is approximately 82.0 g/mol, rounded to three significant figures.

When a gas is collected over water, the partial pressure of water must be subtracted from the total pressure. If the total pressure was 761 mmHg and the pressure for water is 17.2 torr, what is the pressure due to the gas collected

Answers

Answer is: the partial pressure of the hydrogen 500 mmHg.

p(total) = 523.8 mmHg.

p(water) = 23.8 mmHg.

p(total) = m(water) + p(hydrogen).

p(hydrogen) = p(total) - p(water)..

p(hydrogen) = 523.8 mmHg - 23.8 mmHg.

p(hydrogen) = 500 mmHg.

mmHg or millimeter of mercury is a manometric unit of pressure.

The second largest use of charcoal is in industrial applications in the form of activated charcoal. The activation process involves heating the charcoal subjecting it to steam or treating with a chemical to both remove substances that have adhered to it as well as break it down into finer particles and thus increase the surface area. Activated carbon has been used for its adsorptive properties as a ‘universal antidote’ in cases of poisonings, as a filter aid agent, and in decolorization processes.
