Answer:

d) All have identical pressures

Explanation:

The kinetic molecular theory explains how gas molecules behave in a container. By this theory, the gas particles behave like hard, spherical objects in a state of constant, random motion; these particles collide between them and at the walls of the container. Besides, the kinetic energy of the gas depends only on the temperature.

The pressure is the force that the particles are applying under some area, so by the theory, it depends on the number of moles (amount of particles that collides and make the force), the volume of the container and the kinetic energy, or the temperature.

Because all gases have the same number of moles and are at the same temperature and the same volume, they'll have the same pressure.

Answer:

Demonstration 1 showed a chemical change because a new gaseous substance was formed, and demonstration 2 showed a physical change because liquid water became water vapor.

Explanation:

Chemical changes alter the chemical makeup of a subject, and a physical change only alters the appearance of a subject, not the chemical makeup.

According to the oxygen-hemoglobin dissociation curve, PO2 in the lungs of 100 mm Hg results in Hb being 98% saturated. At high
Ad libitum [116K]

Answer:

Hb would be 78.4% saturated.

Explanation:

This problem can be solved by using simple unitary method.

At 100 mm Hg pressure of oxygen, Hb is saturated by 98%

So, at 1 mm Hg pressure of oxygen, Hb is saturated by \frac{98}{100}%

Hence, at 80 mm Hg pressure of oxygen, Hb is saturated by \frac{98\times 80}{100}% or 78.4%

Therefore, at 80 mm Hg pressure of oxygen in the lungs, Hb would be 78.4% saturated.

Ethylene glycol (antifreeze) has a density of 1.11 g/cm3. What is the mass in grams of 387 mL of ethylene glycol?
harkovskaia [24]
To start, 1 cubic centimeter = 1 milliliter, so now you have 1.11g/mL.

Now multiply 1.11 by 387 to get the mass of antifreeze in grams, since the mL is canceled out.

387 mL x 1.11g/mL = 429.57 g
