4P + 5O2 → P4O10 How many phosphorus (P) atoms are on each side of the equation? How many oxygen atoms are on each side?

Answers

Answer:

4 p and 10 O on both sides

Explanation:

on the reactant side you can see easily that there are 4 P. With the oxygen on the reactant side you take the coefficient (5) times the subscript (2) which gives a total of 10 Oxygens.

On the product side there is a subscript of 4 next to the p, and a subscript of 10 next to the O

They are equal on both sides so you are done.

Eric said, “I took these photos from the same hill behind my house on three different nights. If half of the Moon is always illuminated and the other half is always dark, then why does the Moon look so different on different nights?”

Answers

Answer:

it is called waning and waxing It's because the moon is a world in space, just as Earth is. Like Earth, the moon is always half illuminated by the sun; the round globe of the moon has a day side and a night side. And, like Earth, the moon is always moving through space. it is also because of the position of the earth and the moon.

Explanation:

The reason why the moon looks so different on different nights is because of a phenomenon called:

Waning and Waxing

Waning and Waxing is a phenomenon which is used to describe the reason why the moon is half illuminated by the sun and why the other half is dark.

This is because the moon is always moving through space and like te Earth it has a "day and night" schedule depending on the location on the earth's crust.

Why do you think these fossils are important to the study of evolution? Do you think the word transitional is a scientifically appropriate description for these fossils?

Knowing how fossils form, do you think it’s likely that humans will ever piece together a complete fossil record for every species that ever existed on Earth? Why or why not?

Answers

Answer:

- Fossils are an important part of the study of human evolution When a plant or animal dies its body is acted upon by various forces of nature like wind, air; With time body decomposes and gets covered by layers of soil in millions of years Due to increasing pressure with every layer of soil getting added it creates an impression of the body while it further decays, Even it is acted upon by hot temperature inside So even after millions of years of extinction of a species we can study about it looking at its impression in soil known as Fossil one of the ways is.
