Answer:- C. decrease in temperature.
Explanations:- Solubility of a solid increases if the pressure is increased as the high pressure helps the solid to get dissolved in the solvent.
If the surface area of the solute is increased then more and more solute comes into the contact of the solvent and the solubility increases.
If the stirring is increased then it also helps the solute to get dissolved into the solvent.
Solubility of solids is directly proportional to the temperature.
So, if the temperature is decreased then solubility of the solute is also decreased.
Answer:
980,536.2 grams
Explanation:
The mass of a compound is equal to its moles times its molar mass.
The molar mass of PCl3 is 137.33 g/mol
137.33 x 7.14 x 10^3 = 980,536.2
It is on a plate boundary so there are a lot of volcanoes in that area. All the volcanoes form a "ring" around the plate boundary.
Answer : B
Explanation : Just did it
C - electric charges have electric fields. imagine a magnet - charge is distributed in space in the same way magnetic field is. if you can imagine how two magnets of the same sign (++/--) repel each other, you can apply that concept to electric charge/field.
