Answer:
I don't know if you can directly prove it with evidence if you haven't observed it but you can maybe take an educated guess by the aftermath of it?
For example, you see a burnt log. At this time, people don't know what fire is. After we study the log, we could see that it takes extreme temperature in order to burn the log and that would help people see that there is a force like fire that can cause this. In a way, finding out that extreme temperatures burns stuff is another step closer to the discovery and proof of fire
I hope that makes sense
The chemical reaction shows the change that took place in the reaction. The number of moles of LiOH reacted is 1.16 moles.
<h3>What is chemical reaction?</h3>
The term chemical reaction has to do with the combination of two substances to yiled a new one that is different from each of the reactants. From this reaction; .
Number of moles of CO2 = 25.5 g/44 g/mol = 0.58 moles
Since 1 mole of CO2 reacts with 2 moles of LiOH
0.58 moles reacts with 0.58 moles * 2 moles/ 1 mole
= 1.16 moles

Answer:
11.958129200057586 molecules
Explanation:
The density is the ratio of the substance's mass to its volume. Density is an extensive property even though mass and volume are both intensive properties. It is because density is constant for each substance at a specified temperature and pressure. The equation is
Density = mass/volume
Substituting the values,
1.40 g/cm³ = [500 mg * (1 g/1000 mg)](Volume)
Volume = 0.357 cm³
Explanation:
solid: table, biscuit
