The correct answer is:

Metals

They are all alkali and transition metals

Explanation:

The periodic table includes elements clustered into groups with comparable properties. Alkali metals are reactive, soft metals with low densities. Transition metals are unreactive metals that have many have common uses. Halogens are reactive non-metals that form glowing vapors.

What are the masses of the four different brcl molecules?
tatyana61 [14]

Through mass spectrometry, we can define 4 different isotopes of the BrCl molecule:

⁸¹Br³⁷Cl, ⁸¹Br³⁵Cl, ⁷⁹Br³⁷Cl, ⁷⁹Br³⁵Cl  

Masses of the different individual isotopes:

³⁷Cl=36.966

³⁵Cl=34.968

⁸¹Br=80.916

⁷⁹Br=78.918

Masses of 4 different isotopes of the BrCl molecule:

⁸¹Br³⁷Cl=80.916+36.966=117.882

⁸¹Br³⁵Cl=80.916+34.968=115.884

⁷⁹Br³⁷Cl=78.918+36.966=115.884

⁷⁹Br³⁵Cl=78.918+34.968=113.886

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.

BRAINLIESTTT !!! Pls help ASAP !!!! How does plasma state of matter interact with other matter?
Ivan

Answer:

Plasma is a state of matter in which an ionized gaseous substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate the behaviour of the matter. The plasma state can be contrasted with the other states: solid, liquid, and gas
