The food chain always begins with a sun without it there would be no food chain... hope this helped!
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.
Answer:
4NH3(g) + 502(g) – 4NO(g) + 6H20(9)
Explanation:
= 100(9)
Answer:
Option D:
evaporation from lakes and rivers
Explanation:
The water cycle is a natural cycle that shows how water moves and circulates within a natural environment. Water usually moves between the hydrosphere and the atmosphere through evaporation and condensation.
When water evaporates from the hydrosphere (the water bodies), it goes up into the atmosphere where it cools to become clouds. As more water evaporates, the clouds formed increase in mass. Once the clouds are too heavy to be held up in the sky, they fall down as precipitation (rain, snow, hail) into the water bodies and surrounding land below.
Answer: C4H
Explanation:
An hydrocarbon is a compound with carbon and hydrogen atoms only covalently linked together.
Thus, all hydrocarbons have a basic formula of CH.
Now, mass of hydrocarbon = 100%
Mass of hydrogen = 20%
Mass of carbon = (100% - 20%) = 80%
i.e Carbon : Hydrogen
= 80% : 20%
= (80% / 20%)
= 4 : 1
Thus, the empirical formula of the hydrocarbon is C4H
