If volume is increased, the number of collisions per second... decreases or increases?

Chemistry
1 answer:
Kaylis [27]3 years ago

Answer:

if volume is increased, the number of collisions per second decreases.

Explanation:

volume is inversely proportional to pressure. Increase in volume leads to decrease in pressure and decrease in volume leads to increase in pressure.

if the pressure is high, it leads to increase in the number of collisions. If the pressure is low, it leads to decrease int he number of collisions.

therefore since volume is inversely proportional, when volume is increased, the pressure decreases and thus the number of collisions decreases.

Which of the following does not participate in, nor is a component of, the electron transport chain? (Remember that molecules ca
Yanka [14]

Answer:

A) coenzyme A

Explanation:

The NADH and FADH₂ are the energy rich molecules which are formed in the processes like glycolysis, TCA cycle and the fatty acid oxidation as they contain pair of electrons which have very high transfer potential.

As a result of the energy produced when these molecules transfer their electrons to the oxygen , ATP is generated by a series of electron carriers which collectively is called electron transport chain (ETC).

<u>The components of chain include Fe–S centers, Non-heme, FMN, coenzyme Q, and cytochromes . </u>

The energy derived from the transfer of electrons is used to pump the protons across mitochondrial membrane.

As a result, an electrochemical gradient is generated which results in some energy which is then harnessed by the ATP synthase to form ATP.

An unknown material has a mass of 5.75 g and a volume of 7.5 cm3.
Shtirlitz [24]

Hey there!:

Mass = 5.75 g

Volume = 7.5 cm³

Therefore:

Density = mass / volume

D = 5.75 / 7.5

D = 0.7 g/cm³

Answer C

Hope that helps!

Let's say that you were given the following
mezya [45]

Answer:

V2~0.4839M

Explanation:

We're going to use Boyles law to answer the question.

Boyle's law:

P1V1=P2V2

P1=151mmHg

P2=166mmHg

V1=0.532L

V2=?

V2=(P1 x V1)/P2

V2=(151 x 0.532)/166

V2~0.4839M

Hope it helps:)
