Astudent states that this structural formula represents a hydrocarbon bhh h-c-c-0-h hh is the student correct? yes, a hydrocarbon is any compound that contains a carbon backbone, yes, a hydrocarbon is any compound that contains hydrogen and oxygen, no, a hydrocarbon contains only carbon and hydrogen atoms, no a hydrocarbon contains at least one double or triple bond

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

the wires in the toaster turning red and the toast crisping and turning brown

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
