Answer:
I would say an airport
Explanation:
why because it is ran by the government
Options are as follow,
<span>A) Covalent bonds are formed by metals and nonmetals.
B) Covalent bonds are are typical of carbon compounds.
C) Covalent bonds are created by the attractions between oppositely charged ions.
D) Covalent bonds break apart when dissolved in water and allow for the conduction of electricity.
</span><span>Answer:
Covalent bonds are formed by mutual sharing of electrons between two atoms of having electronegativity difference less than 1.7. Among given options only option-B seems correct.
Explanation:
Carbon containing compounds are almost covalent in nature. Majority of organic compounds are made up of carbon, hydrogen, oxygen and nitrogen. And carbon makes covalent bonds with all these atoms.
Result:
</span>Option-B is correct.
Answer:
c) H2O and OH−
Explanation:
Acids are the species which furnish hydrogen ions in the solution or is capable of forming bonds with electron pair species as they are electron deficient species.
When an acid donates a proton, it changes into a base which is known as its conjugate base.
Bases are the species which furnish hydroxide ions in the solution or is capable of forming bonds with electron deficient species as they are electron rich species. When a base accepts a proton, it changes into a acid which is known as its conjugate acid.
The acid and the base which is only differ by absence or presence of the proton are known as acid conjugate base pair.
Thus, for the reaction,
The base is 
and the conjugate acid of the base is 
.
Also, The base is 
and the conjugate acid of the base is 
.
<u>Correct option is :- c) H2O and OH−</u>
Some forces can be shear gravity and compression that are putting force on the bed
Answer:
wavelength = 0.56 × 10⁻² m
Explanation:
Given data:
Frequency of radiation = 5.4 × 10¹⁰ Hz
Wavelength = ?
Solution:
Formula:
speed of light = wavelength × frequency
wavelength = speed of light / frequency
wavelength = 3 × 10⁸ m/s / 5.4 × 10¹⁰ Hz ( Hz= 1/s)
wavelength = 0.56 × 10⁻² m
