Answer:

A liquid changing to a gas is considered a physical change because it involves a change in one or more physical properties, but no change in the fundamental components that make up the substance.

How does a volcano form?
stealth61 [152]
A volcano is formed when magma (Lava) spews up from deep within the earth. After each eruption the Volcano gets bigger and bigger, so basically after periods of time the volcano will get larger. Lava will rise in cracks in the earth or weak spots in the earths crust. The pressure is relieved thus resulting in a volcanic eruptions it forms the new crust and then eventually builds up in that spot making a volcano. They also form in places called hot spots and various other places.

The given questions belongs to the concept of limiting reagent.

The number of moles of carbon dioxide produced when 4.6 moles of dioxygen reacts is 4.6 moles.

<h3 /><h3>What is Limiting Reagent ?</h3>

The limiting reagent (or limiting reactant or limiting agent) in a chemical reaction is a reactant that is totally consumed when the chemical reaction is completed.

Given ;

Moles of Oxygen = 4.6

To find;

Moles of Carbon di oxide = ?

The reaction that forms CO_2 is as follows:

C(s) + O_2(g) -->  CO_2(g)

This means that O_2 is consumed and  CO_2 is produced in a 1:1 ratio.

If we consume 4.6 mol  O_2, then we produce 4.6 mol  CO_2 .

Hence, 4.6 mol  CO_2 are produced when 4.6 mol of oxygen reacts.

Serga [27]

Answer:

  about 37 years

Explanation:

If 100% of the estimated reserves are used at the current rate, it will take ...

  (1.234·10^12 bbl)/(3.3·10^10 bbl/yr) = 37.4 yr

It will take about 37 years to deplete the reserves.
