A pound of wood produces about 1 kWh of electricity when combusted to produce electricity. The burning of the wood in this way is clean, emiting only biogenic CO2. Consider that wood is approximately 50% carbon. The electricity created from wood burning is used to displace grid electricity. What is the carbon footprint of 100,000 lb of burnt wood, based on this process

it would be a gas formation

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.

idk what is it? is this a question that you know the answer or u dont
