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

Answer:

B. The emiision spectrum of an element

Explanation:

just took the test

Answer:

b

Explanation:

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

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.

In the absence of gravity, plants use other environmental factors, such as light, to orient and guide growth. A bank of light emitting diodes (LEDs) above the plants produces a spectrum of light suited for the plants' growth.

Answer:

273.15° C

Explanation: Ideal gasses tend to double in volume when their temperature doubles. 0°C = 273.15K so double 273.15 gives 546.3K.

Converting back to Celcius

546.3-273.15 =273.15°C

Answer:

Oxygen, nitrogen, and carbon dioxide are chemically bonded to one another.

other answer wrong coz carbon dioxide can be broken down into 1 Carbon, 2 Oxygen

Explanation:

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

Thus, the correct option for this question is A.

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.

Therefore, oxygen, nitrogen, and carbon dioxide are all classified as pure substances is the statement that best describes these three components of air. Thus, the correct option for this question is A.

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%

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.
