Is litmus paper an indicator? Litmus paper is filter paper which has been treated with a natural water-soluble dye obtained from lichens. The resulting piece of paper, called “litmus paper”, can be used as a pH indicator. Is pH paper better than litmus paper? pH strips change color when they come in contact with a […]

How do you calculate NEP in ecology? NEP = GPP – ER, with GPP = gross primary production. NEP refers to production (= positive when the ecosystem is a CO2 sink, negative for a CO2 source) while NEE is a flux (= negative when the ecosystem is acting as a CO2 sink, positive for a […]

What is Moment Mass? Moment of mass simply implies Distance × Mass. For a system of n particles, in order to obtain the center of mass – we consider a reference point. The effective mass times the distance to center of mass (which is a moment) will be equal to the sum of moments of […]

Are 2 6 volt batteries better than 2 12 volt batteries? If you’re comparing a dual 6-volt arrangement vs a dual 12-volt arrangement with deep cycle in both cases and approximately the same capacity and same quality on both sets, then the answer is no. Does series increase voltage? In a series connection, batteries of […]

What is the cheapest way to produce hydrogen? The carbon monoxide is reacted with water to produce additional hydrogen. This method is the cheapest, most efficient, and most common.
