Answer:
Techniques and Tests
Qualitative analysis typically measures changes in color, melting point, odor, reactivity, radioactivity, boiling point, bubble production, and precipitation.
Answer:
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
Hope this is what you mean be hot spot!
I hope this helps you!
Have a great day

9.0 grams because the atomic mass of 1 mole of Neon STP(22.4L) is 20.17 and cross multiply 10.0g(given) by the 20.17, and divide by 22.4L to get 9.00 grams of Neon to match 10L container at STP
Answer is: below magnesium in group 2 or in group 1 (left from magnesium).
Reactivity series is an empirical progression of a series of metals, arranged by their reactivity from highest to lowest (alkaline metals have highest reactivity and Noble metals lowest reactivity).
This series are used to summarize information about the reactions of metals with acids or water, double displacement reactions (more reactive metals displace metals with lower reactivity) and the extraction of metals from their ores.
Sodium and potassium (group 1 - alkaline metal) are more reactive than magnesium.
Strontium and barium (group 2 in periodic table) are higher in this group from magnesium. Strontium is stronger reducing agent than magnesium, gives electrons easier.
