within a balloon there are 3 types of gases. the first gas, A, is 6.0 grams in amount, the second gas, B, is 4.0 grams and the last, C, is 3.5 grams. The molar mass of gas "A" is 13.56 g/mol, "B" is 11.76 g/mol and "C" is 12.07 g/mol. If the total pressure inside the balloon is 15 atm, what is the partial pressure of each gas?

Answers

Answer 1

Answer:

Partial pressure of Gas A = 3.91 atm

Partial pressure of Gas B = 5.10 atm

Partial pressure of Gas C = 5.99 atm

Explanation:

Number of moles of gas A;

n_A = 13.56 g/mol ÷ 6 g = 2.25 moles

Number of moles of gas B;

n_B = 11.76 g/mol ÷ 4 g

n_B = 2.94 moles

Number of moles of gas C;

n_C = 12.07 g/mole ÷ 3.5 moles

n_C = 3.45 moles

Total number of moles = n_A + n_B + n_C = 2.25 + 2.94 + 3.45 = 8.64 moles

Mole fraction of gas A; X_a = 2.25/8.64

Mole fraction of gas B;X_b = 2.94/8.64

Mole fraction of gas C;X_c = 3.45/8.64

Now, partial pressure of each gas will be;

Mole fraction × Total pressure

We are given total pressure of 15 atm.

Thus;

P_a = (2.25/8.64) × 15

P_a = 3.91 atm

P_b = (2.94/8.64) × 15

P_b = 5.10 atm

P_c = (3.45/8.64) × 15

P_c = 5.99 atm

Thus;

Partial pressure of Gas A = 3.91 atm

Partial pressure of Gas B = 5.10 atm

Partial pressure of Gas C = 5.99 atm

What is atom?

Atom, the smallest unit of matter that may be separated without releasing electrically charged particles. It is also the tiniest unit of matter with the characteristics of a chemical substance. As a result, the atomic is the fundamental building component of chemistry.

The majority of the molecule is empty space. The rest of the structure is made up of a positive-charged nucleus of neutrons and protons surrounding by a swarm of negative-charged electrons. In comparison to electrons, the lightest charge particles in nature, nuclear nucleus is small yet dense. The atoms in the liquid would be vibrating in position.

Therefore, the correct option is option B.

Which reason best explains why metals are malleable?
A. because they have delocalized electrons
B. because they have localized electrons
C. because they have ionic bonds
D. because they have rigid bonds

Answers

Answer:

A

Explanation:

because they have delocalized electrons

Metals are malleable because they have delocalized electrons which are capable of forming ionic bonds.

What is an ionic bond?

Ionic bond or electrovalent bond is a type of bond which is formed between two elements when there is an exchange of electrons which takes place between  the atoms resulting in the formation of ions.

When the atom looses an electron it develops a positive charge and forms an ion called the cation while the other atom gains the electron and develops a negative charge  and forms an ion called the anion.

As the two atoms are oppositely charged they attract each other which results in the formation of a bond called the ionic bond.Compounds having ionic bonds are malleable and have high melting points.They are also brittle in nature.

b. Deliquescent
c. Efflorescentd.
d. Hygroscopic

Answers

Answer:

c. Efflorescent

Explanation:

Some hydrated salts, when exposed to the atmosphere, give off part of all of their water of crystallization spontaneously to form a lower dehydrated or anhydrous salt. Such salts are known as efflorescent and the phenomenon is called Efflorescence.

Efflorescence occurs when the hydrate's aqueous vapor pressure is greater than the water vapor's partial pressure in the air. For example, because the vapor pressures of washing soda (Na2CO3·10H2O) and Glauber's salt (Na2SO4·10H2O) normally exceed that of the water vapor in the atmosphere, these salts effloresce (i.e., lose all or part of their water of hydration), and their surfaces assume a powdery appearance.

4 bigots = 1 gram gold
How many grams of gold did Bob take from the aliens?

Answers

Answer : The number of grams of gold Bob take from the aliens will be 0.5.

Explanation :

As we are given that:

1 zygot = 3 trigots

3 trigots = 2 bigots

4 bigots = 1 gram gold

Now we have to determine the number of grams of gold Bob take from the aliens.

The number of grams of gold Bob take from the aliens will be equal to:

[tex]\frac{1\text{ zygot}}{1}\times \frac{3\text{ trigots }}{1\text{ zygot}}\times \frac{2\text{ bigots }}{3\text{ trigots }}\times \frac{2\text{ gram gold}}{4\text{ bigots }}[/tex]

= [tex]\frac{6}{12}[/tex] gram gold

= [tex]\frac{1}{2}[/tex] gram gold

=  0.5 gram gold

Hence, the number of grams of gold Bob take from the aliens will be 0.5.

Given data:

Mass of iron(III) oxide = 320 kg (320000 g)

Number of moles of iron atoms = ?

Solution:

First of all we will calculate the number of moles of iron(III) oxide.

Number of moles = mass/molar mass

Number of moles = 320000 g/ 159.69 g/mol

in an experiment it was found that the total charge on an oil
drop was 5.93 X 10^-18 C How many negative charges does
the drop contain? (#51)

Answers

Answer:

37 negative charges.

Explanation:

We're being asked to determine how many negative charges a drop contains from an oil drop experiment where the total charge was 5.93x10-18 C. The drop contains 37 negative charges.

It was stated and identified that we are to attempt question #51 alone.

From the given information;

The total charge on an oil drop = 5.93 × 10⁻¹⁸ C

According to Oil drop experiment carried out by Robert Milliken in (1910);

In the oil drop laboratory experiment, It was possible for Him to substitute oil for water (because water quickly evaporate). Robert Milikan adjusted the electrical voltage among the two metal plates while the oil drop continues to drop until it stopped. When the drop was stopped, the gravitational downward force on the oil drop was equivalent to the electrical upward force on the charges thereby enabling Robert Millikan to be able to estimate the electrical charge drop.

Robert Milliken identified that the magnitude of a single negative electron charge is:

= 1.6 × 10⁻¹⁹ C

If in an experiment, the total charge =  5.93 × 10⁻¹⁸ C

Then;

The number of negative charges in the oil drop can be calculated as;

[tex]\mathbf{=\dfrac{5.93 \times 10^{-18}}{1.6 \times 10^{-19}}}[/tex]

= 37.063 negative charges

Therefore, we can conclude that the numbers of negative charges contained in the total drop = 37.063.
