Answer:
Fossils, Glaciers, Coastlines.
Explanation:
Evidence of plate tectonic theory are fossils, fossils of the same species were found oceans apart. also glaciers evidence of glaciers were found in places with warm climates. coastlines coastlines look like they fit in a puzzle.
5.8 is 11.2% of what number
51.786 grams
Explanation:
(6.1). The reaction equation will be as follows.
Assuming the value of 
as 
and let the solubility of each specie involved in this reaction is "s". The expression for will be as follows.
![K_{sp} = [Ba^{2+}][SO^{-}_{2}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%20%3D%20%5BBa%5E%7B2%2B%7D%5D%5BSO%5E%7B-%7D_%7B2%7D%5D)
(Solids are nor considered)
= 
s = 
= 
= 
Therefore, solubility of barium sulfate in water is .
(6.2). As the molar mass of 
is 233.38 g/mol
Therefore, the solubility is g/L will be calculated as follows.
= 
Therefore, solubility of barium sulfate in grams per liter is .
Answer:
Model 1 represents the old geocentric model of the solar system and Model 2 represents the newer heliocentric model of the solar system.
Explanation:
Model 1 has earth in the center, therefore it is geocentric. the geocentric model of the solar system is old. Nobody believes in it anymore because it is scientifically inaccurate.
Model 2 has the sun in the center, therefore it is heliocentric. This is the newer model of the solar system.
