Ok so all are in the alkali family also they are all metals and in group 1 but I think the one that might reacts quickest is Li because it has less AMU
Solids- wood, sand, brick, rock
Liquids- water, milk, blood, coffee
Gases- air, helium, nitrogen, hydrogen
Answer: 121.7558 amu
Explanation:
Average atomic mass of the unknown element =
(Mass of isotope 1 x Relative Abundance of Isotope 1) + ( Mass of Isotope 2 x Relative Abundance of Isotope 2)
(120.9 x 0.5721) + (122.9 x 0.4279) = 69.16689 + 52.58891
Average mass of the unknown element = 121.7558 amu
The production of a gas is different because unlike the heating curve, there was no heat applied to this experiment, and the experiment was a chemical reaction.
<h3>What is a Heating curve?</h3>
This shows the relationship between the temperature of the heating system and the air temperature in the outer environment.
The chemical reaction emitted heat as against the other which involved heat application which is why water formation in this curve was different.

Answer:
An Acid Test
An acid test is any qualitative chemical or metallurgical assay which uses acid ( most commonly), and historically, the use of a strong acid to distinguish gold from base metals.
