1. A gas sample at a pressure of 5.00 atm has a volume of 3.00 L. If the gas pressure is changed to 760 mm Hg, what volume will
tatyana61 [14]

Answer:

V₂ =  15.00 atm

Explanation:

Given data:

Initial pressure = 5.00 atm

Initial volume = 3.00 L

Final pressure = 760 mmHg ( 760/760 = 1 atm)

Final volume = ?

Solution:

P₁V₁ = P₂V₂

V₂ = P₁V₁ /  P₂

V₂ =  5.00 atm × 3.00 L / 1 atm

V₂ =  15.00 atm

Which statement is true regarding carbonic acid (H 2CO 3)? If body fluids are too alkaline, carbonic acid is excreted through th
dimaraw [331]

Answer:

the correct option is : If body fluids are too acidic, carbonic acid is excreted through the respiratory system in the form of carbon dioxide and water.

Explanation:

Metabolic acidosis is compensated by two systems, the renal and respiratory systems.

In the case of the respiratory system, the mechanism it uses to compensate for this phenomenon is to release the carbonic acid molecule dissociated into its components, that is, in the form of water and carbon dioxide.

The greater the acidosis, the more hyperventilation the person will have, and this is because they seek to eliminate carbonic acid more efficiently and quickly, along with renal excision.

The metabolic acidosis generated by carbonic acid is lethal, since the proteins in our body are denatured and the homeostasis of all systems is corrupted.

In equal-arm balances from the early twentieth century, it is sometimes observed that an aluminum sheet hangs from one of the ar
alexandr402 [8]

Answer:

Currents in the aluminum sheet set up a magnetic field that opposes the oscillations

Explanation:

It has been stated in the question that the aluminum sheet hangs from one of the arms and passes between the poles of the magnet and causes the magnetic field to decay rapidly. In the absence of this magnetic breaking, the oscillation may continue for a long time.

As the aluminum hangs from one of the sheets and passes between the poles of the magnet, the magnetic flux linked to the sheet changes and emf is induced in the sheet according to Lenz law. As a result of this induced emf, eddy currents are developed on the plate. The Eddy currents opposes the magnetic force on the aluminum sheets. This opposes the oscillation of the aluminum sheet and causes it to come to rest.
