Why are covalent bonds between hydrogen and nitrogen or oxygen polar?

Chemistry
1 answer:
yaroslaw [1]3 years ago
6 0

Answer:

The answer to your question is below

Explanation:

Covalent bonds are bonds between to atoms that share a pair of electrons, there are three kinds of covalent bonds but I'll describe only two:

Covalent non polar bond: is a covalent bond between two elements of the same element. Ex two hydrogens, two chlorine, two oxygenes, etc.

Covalent polar bond: is a covalent bond between 2 elements of different elements, for example: hydrogen and chlorine or nitrogen, they are polar because on of the element that form it is smaller than the other one, then a partial positive and a partial negative charge is formed.

Hydrophobic compounds dissolve in
Anastaziya [24]
Hydrophobic molecules tend to be nonpolar molecules that group together to form micelles rather than be exposed to water. Hydrophobic molecules typically dissolve in nonpolar solvents (e.g., organic solvents).

In a high-mass star, hydrogen fusion occurs via the choose one: a. spin-spin interaction. b. proton-proton chain. c. cno cycle.
Lerok [7]

In a high-mass star, hydrogen fusion occurs via the CNO (Carbon-Nitrogen-Oxygen) cycle.

According to the life cycle of a star, there are three main phases in the life of a star: The initial phase (a quick phase), short phase or supergiant phase and death phase or supernova explosion.

the CNO cycle means Carbon-Nitrogen-Oxygen cycle and this process tale place during main sequence phase.

In this phase, hydrogen fuses into helium as a result of six different reaction taking place inside a star.

The first step of the sequence begins when the nucleus of carbon 12 isotope emits gamma rays after capturing a proton and produces nitrogen-13.

This whole cycle is known as stellar nucleosynthesis.

Calculate the volume of a 3.50 M solution of H2SO4 made from 49 g of H2SO4
maxonik [38]

Answer:

0.143L

Explanation:

Molar mass of H2SO4 = 98g/Mol

No of mole = mass/molar mass

No of mole= 49/98 = 0.5 mol

No of mol = concentration × volume

Volume = n/C = 0.5/3.5 = 0.143L

What general rule can be followed when choosing a type of solvent to dissolve a particular solid?
Fittoniya [83]
 <span>the polarity of the solute or the solvent. 

for example: 
oil will not mix with water because oil molecules are nonpolar however water moleculses are polar. so, they will not mix with each other. 

when we put sodium chloride in water, sodium chloride will be easily dissoved. because both sodium chloride and water are polar. 

in other case, if we put sodium chloride and hexane together. sodium chloride will not dissove in hexane, because hexane is a nonpolar solvent. 

finally, if we try to mix hexane and bromine together, they will mix uniformly. because both hexane and bromine are nonpolar. (note: most diatomic molecules are nonpolar, such as hydrogen gas, oxygen gas, chlorine gas, etc. ) 

so just remember, nonpolar and nonpolar will dissovle each other. and polar and polar will dissolve each other.</span>
