The oldest fossils and evidence of modern humans on earth are around 200,000 years old. Before that time lived the ancestors of

modern humans and Neanderthals. If all of earth’s history was compressed into 12 hours, what time would you first see modern humans?

Answer:

I would say around the 11th or 12th hour

Explanation:

seeing as the question calls for ALL of earth's history compressed into 12 hours the timeline should be similar to this: Earth was born at midnight, at around 2-3 AM land masses form, Right after that, life begins, For around 8 hours (11 PM) life is confined in water, right after that we have plants, 22 minutes later we have dinosaurs, 22 minutes later we have mammals, 5 minutes later dinosaurs are extinct, 6 minutes later we have people. So it's most likely the 12th hour. I hope this helps.

You would see modern humans in the last hour, specifically possibly closer to the last couple of minutes if the earth really is as old as scientists predict

Why is it important to know where a resource, that you're using, is renewable or nonrenewable?
NemiM [27]

Answer:

It is important to know if a resource is renewable or non-renewable because renewable resources are self-sustaining (unlike non-renewable resources). If a non-renewable resource is used too often, that resource may eventually become non-existant. This can also happen to renewable resources, but it is more difficult.

How many moles are present in 3.4 x 1023 atoms of Na?
Andrej [43]
<h3><u>moles of H2SO4</u></h3>

Avogadro's number (6.022 × 1023) is defined as the number of atoms, molecules, or "units of anything" that are in a mole of that thing. So to find the number of moles in 3.4 x 1023 molecules of H2SO4, divide by 6.022 × 1023 molecules/mole and you get 0.5646 moles but there are only 2 sig figs in the given so we need to round to 2 sig figs. There are 0.56 moles in 3.4 x 1023 molecules of H2SO4

Note the way this works is to make sure the units are going to give us moles. To check, we do division of the units just like we were dividing two fractions:

(molecules of H2SO4) = (molecules of H2SO4)/1 and so we have 3.4 x 1023/6.022 × 1023 [(molecules of H2SO4)/1]/[(molecules of H2SO4)/(moles of H2SO4)]. Now, invert the denominator and multiply:
