The answer is A. An sp3 hybridized atom will have a total of 4 single bonds and lone pairs. Since carbon here is attached to four hydrogens, it must be sp3 hybridized. The C-H bonds are also the least polar bonds here, even though there is a slight amount of electronegativity difference between the two.
The presence of H3O+ is the hydronium ion, and one definition of an acid is something that donates a proton (H+). HCl in this case does just that. Basic solution forming with NaOH and water: ... NaOH + H2O ==>Na+ + OH- so it donates or produces OH- ions, thus making a basic solution
Unique archaea characteristics include their ability to live in extremely hot or chemically aggressive environments, and they can be found across the Earth, wherever bacteria survive. Those archaea that live in extreme habitats such as hot springs and deep-sea vents are called extremophiles.
Answer:
frequency = velocity of light /wavelength
wavelength = velocity / frequency
=3 x10^8 / 5.9 x 10^11
=0.508 x 10^-3.
