A contains 38.5 g of tin for each 12.3 g of fluorine:
<span>mole ratio: </span>
<span>(38.5 g)/(118.71 g/mol):(12.3 g)/(18.998 g/mol) = 0.324:0.647 = 1:2 ⇒ SnF₂ </span>
<span>B contains 56.5 g of tin for each 36.2 g of fluorine: </span>
<span>mole ratio: </span>
<span>(56.5 g)/(118.71 g/mol):(36.2 g)/(18.998 g/mol) = 0.476:1.905 = 1:4 ⇒ SnF₄

Kinetic energy of the molecules increases and we are close to boiling point liquids. Then strain the liquid and gas pressure reached equilibrium
.
Answer:
4 is the best answer but incomplete.
Explanation:
Heat from the Earth is also radiated back into space. The in and out of energy is what makes it an open system.
