Which of the following factors decreases the rate of solubility?
belka [17]

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.

Roundup, an herbicide manufactured by Monsanto, has the formula C3H8NO5P. How many moles of molecules are there in a 783.5-g sam
anastassius [24]
First, is to solve the molar mass of the herbicide, with a formula
<span>C3H8NO5P
C3 = 12 ( 3 ) = 36
H8 = 1 ( 8 ) = 8
N = 14
O5 =  16 ( 5 ) = 80
P = 31
so in total the molar mass of </span><span>C3H8NO5P is 36 + 8 + 14 + 80 + 31 = 169 g/mol

number of moles = 783.5 g ( 1 mol / 169 g)
number of moles = 4.64 mol </span><span>C3H8NO5P</span>
