Answers

Answer:

6%

Explanation:

60 g / 1000 g = 6%

The concentration of a solution in 60 g of NaCl are dissolved in 1L of water will be 6%.

What is concentration?

The abundance of an ingredient ratio of the volume of a combination is called concentration. Mass concentration, molar concentration, number concentration, and volume concentration are all examples of mathematical descriptions.

Concentration can be calculated as:

C=m/V.

where, C is concentration , m is mass and V is volume.

It is given that, m = 60 g and V = 1L or 1000 mL.

Now, put the value of given data in above equation.

C= 60/1000

He should make the Moon orbit Earth at an angle to the table, and not parallel. So, the correct option is C.

What is an orbit?

The curving path that an object in space takes around another object as a result of gravity is known as an orbit. Moons orbiting planets, planets orbiting planets, and artificial satellites orbiting the Earth are examples of objects where this is frequently seen.

A route that an object in space follows around another is known as an orbit. A satellite is a thing that orbits the earth. An Earth- or moon-like natural satellite is one possibility. Moons are satellites that orbit many planets. A man-made satellite is also possible, such as the International Space Station.

The solar system's planets, comets, asteroids, and other celestial bodies revolve around the sun. The majority of solar system objects travel along or very near a hypothetical flat surface. The ecliptic plane is the name given to this hypothetical plane.

Therefore, the correct option is C.

A compound is 52.0% zinc 9.6% carbon and 38.4% oxygen. Calculate the empirical formula of the compound.

Answers

Answer:

So a compound is 52% Zinc(Zn), 9.6% Carbon(C), and 38.4% Oxygen (O). Let’s first start off by assuming that we have 100 g of this compound. This means that we have 52 g of Zinc, 9.6 g of Carbon, and 38.4 g of Oxygen.Zinc = 65.38 g/molCarbon = 12 g/molOxygen = 16 g/molThis means we have:52 g of Zn(1 mol Zn/65.38 g of Zn) ≈0.8 mol of Zn.9.6 g of C(1 mol C/12 g of C) = 0.8 mol of C38.4 g of O(1 mol of O/16 g of O) = 2.4 mol of O.

Explanation:

What we want to do next is divide each element by the common factor of all of them, which is 0.8. In most cases, you divide each element by the element with the least amount of moles. After we divide each by 0.8, you’ll notice you have 1 Zn, 1 C, and 3 O. This gives you the empirical formula of ZnCO3, or Zinc Carbonate.

Explanation:

The statement that best describes these three components of air is as follows:

Oxygen, nitrogen, and carbon dioxide are all classified as pure substances.

Thus, the correct option for this question is A.

What is Air?

Air may be defined as the combination of invisible, odorless, and tasteless gases such as oxygen, nitrogen, carbon dioxide, etc. that significantly surround any celestial body like the earth.

A pure substance may be characterized as a type of substance that does not have to be a single chemical element. Due to this, water, nitrogen, carbon dioxide, oxygen, etc. are the valid and most accurate examples of pure substances.

The homogeneous mixture or combination of gases like air can also be remarkably considered a pure substance. It is up to the point until there is no change of phase.

O b. 0.61 CO2/L
O c. 94.87 CO2/L
O d. 6.08 CO2/L​

Answers

The solubility of carbon dioxide at 400 kPa  at room temperature is ;

( B ) 0.61 CO2/L

Given data

pressure of CO₂ = 400 Kpa = 3.95 atm

Kh of CO₂ = 3.3 * 10⁻² mol/L.atm

Calculate the solubility of carbon dioxide

Solubility = pressure * Kh value of CO₂

                = 3.95 atm * 3.3 * 10⁻² mol / L.atm

                = 0.13 mol/l  CO₂

                = 0.61 CO₂ / L

Hence we can conclude that the solubility of CO₂ at 400 kPa is 0.13 mol/l  CO₂.

What is the percentage by mass of water in the compound FeCl3 • 6H20 ?

Answers

Answer:

52.12%

Explanation:

First you need to find the mass of the total molecule. The mass of one atom of Fe is 55.847. The mass of one atom of Cl is 35.453. The mass of O is 16.00, and the mass of H is 1.00. The mass of the whole atom is calculated as follows:

55.847 + 3(35.453) + 6(16.00)+ 12(1.00) = 270.206.

Next calculate the mass of water in the molecule:

(2)1.00 + 16.00 = 18.00(6 molecules) = 108

Finally, divide the mass of water by the mass of the whole molecule and multiply by 100 to get it as a percent:

108/207.206 = 0.52122 x 100 = 52.12%

In response to an aspirin (acetylsalicylic acid) overdose, you would expect to observe which acute compensatory response

Answers

Compensatory responses are the compensation mechanism that maintains the body's fluid levels. The increased alveolar ventilation is seen in aspirin overdose.

What is an aspirin overdose?

Aspirin or acetylsalicylic acid is a general pain reliever that can cause poisoning when overdosed. It results in tinnitus, hyperventilation, increased heart rate, low blood pressure, fever, dehydration, etc.

Aspirin toxicity decreases the pH making the blood more acidic causing increased ventilation through alveoli to remove the excess carbon dioxide to balance the pH levels.

Therefore, in aspirin poisoning, the increased alveolar ventilation is the acute compensatory response.
