Chemistry
1 answer:
ANEK [815]3 years ago
7 0

Answer:

Type of hybridisation

Explanation:

For example , saturated hydrocarbons have sp3 hybridisation while unsaturated hydrocarbons have either sp2 or sp hybridisation.

Example: Ethane( C2H6) has sp3 hybridisation and ethene(C2H4) has sp2 hybridisation and Ethyne(C2H2) has sp hybridization.

Which of the following statements correctly describe(s) the driving forces for diffusion of Na+ and K+ ions through their respec
melomori [17]

Question:

Which of the following statements correctly describe(s) the driving forces for diffusion of Na+ and K+ ions through their respective channels? Select all that apply.

A)The diffusion of Na+ ions into the cell is facilitated by the Na+ concentration gradient across the plasma membrane.

B)The diffusion of Na+ ions into the cell is impeded by the electrical gradient across the plasma membrane.

C)The diffusion of K+ ions out of the cell is impeded by the K+ concentration gradient across the plasma membrane.

D)The diffusion of K+ ions out of the cell is impeded by the electrical gradient across the plasma membrane. The electrochemical gradient is larger for Na+ than for K+.

Answer:

"The concentration gradient and the electro-chemical gradient" describes  the driving forces for diffusion of Na+ and K+ ions through their respective channels

Explanation:

The Na ions diffusion inside the cell is facilitated by the concentration gradient of the Na ions which is present across the plasma membrane. Hence, the diffusion of the K ions which is present outside the cell and will be impeded due to the electrical gradient which is present near the plasma membrane. Thus, the electro-chemical gradient is greater as compared to the Na ion than that of the K ion.

Is potassium fluoride a covalent bond or ionic bond
Ivahew [28]

It's an ionic bond! Potassium is a cation, or a metal with a positive charge, and fluoride is an anion, or a nonmetal with a negative charge.

A covalent bond is the bond between two nonmetals.

Hope this helped!

R spectroscopy can be used to identify which _____________________ are present in a compound.
Nesterboy [21]

Answer:

IR spectroscopy can be used to identify chemical structures are present in compounds.

Explanation:

Infrared spectroscopy is a technique in organic chemistry that can be use use to identify chemical structures present in compounds because it is base on the ability of different functional groups to adsorb infrared light.

This work by shinning the infrared lights into the organic compounds to be identified, some of the frequencies of the infrared lights are adsorbed by the compounds and its identify groups of atoms and molecules in the compound.
