Answer:
CH3+
Explanation:
Sp2 hybridization involves the mixing of on s and two p orbitals. This is observed in CH3+. The ion is trigonal planar with a H-C-H bond angle of 120°.
The anion, CH3^- is sp3 hybridized, hence only CH3+ is sp2 hybridized among the options.
This is a good riddle. The answer is ICE, because ice can break things, even ships like the titanic and it also makes steel weak but when the sun comes it melts away so it’s cowers away.
Death by predators is the normal process of nature and the food chain. Predators eat their prey to survive, and the death isn't useless, it has a purpose.
A death by starvation doesn't serve any purpose in the food chain, it is actually a break in it.
Answer:
it would be D or the forth one
Explanation:
Explanation:
Mass of an electron =9.1×10−28g
∴ mass of one mole
=9.1×10−28×6.02×1023
=54.78×10−4g
