Suppose the plates beneath Earth's surface stopped moving.What do you think would happen?Explain your answer.

Amanda [17]

There would be no more earthquakes or volcanic eruptions as the earth's plate are the cause of both these occurrences.(which can be seen as a positive)
However, the plates allow the earth to cool when they move because they cause heat loss.If the plates were to stop moving the earth would have to loose heat another way and since we cant tell how this would happen, it could be very dangerous.

2zn+o2=2zno <br><br> how many moles of zinc are needed to make 6 moles of zinc oxide?

Temka [501]

Answer:

$\boxed{\text{6 mol}}$

Explanation:

(a) Balanced equation

2Zn + O₂ ⟶ 2ZnO

(b). Calculation

You want to convert moles of ZnO to moles of Zn

The molar ratio is 2 mol Zn:2 mol ZnO

$\text{Moles of Zn} =\text{6 mol ZnO} \times \dfrac{\text{2 mol Zn}}{\text{2 mol ZnO}} = \text{6 mol Zn}\\\\\text{You need }\boxed{\textbf{6 mol of Zn}}\text{ to form 6 mol of ZnO}.$
