Methanol is highly toxicicated and a lot of people have
become blind or died from drinking it. Ethanol, or ethyl alcohol, is the
alcohol associated with "alcoholic" beverages. The yeast cells obtain
energy from enzyme-catalyzed reactions that convert sugar or starch to ethanol
and CO2. C6H12O6(aq) ---->2
CH3CH2OH(aq) + 2 CO2(g)
<span>The correct answer is B. Weight is the force of gravity on an object, and since each planet has a different gravitational force, the weight of an object will change depending on what planet it's on. For example, the moon (although not a planet) has only 1/6 the gravitational force that the earth does, so any object on the moon will weigh 6 times less than what it weighs on the earth. However, mass, volume, and density, will not change from place to place, regardless of gravitational force.</span>

The subject area of Chemistry is a very broad area. So, it is classified into sub-branches like inorganic chemistry, organic chemistry, physical chemistry, quantitative chemistry and many more. But when the basis is on the composition of elements, it is divided into inorganic and organic chemistry. Compounds containing the element Carbon are all under organic chemistry. If they do not contain carbon, they are considered as inorganic.
During the early times, the only differentiation between these two sub branches is the vital theory. This theory proposes that all things that have life can be only made by nature alone are inorganic. But thing was disproved by Wohler when he was able to synthesize urea from inorganic compounds. Thus, today the only differentiation is the carbon atom.
