Hey there
Thats easy
Precipitation occurs when cations and anions in aqueous solution combine to form an insoluble ionic compound called precipitation. So, you can refer to a solubility chart or draw polar/nonpolar lewis structures, that might be helpful.
Remember water is polar so polar molecules will dissolve in water
Answer:
It would be the last one because the way earth is tilted the sun rays would be pointing at the Northern Hemisphere more than the Southern Hemisphere
Answer: A solution is made by dissolving 27.8 g of nicotine (Molar Mass = 160 g/mol) in 145 g of cyclohexane (C6H12) to form 142 mL of solution. Calculate the mole fraction of the solute and the molarity, respectively, of this solution.
Explanation:
[H+] = ?
pH = -log[H+]
[H+] = 10^-pH
[H+] = 10^-11,3
[H+] = 5,01 × 10^-12 mol/l
Answer: H+ concentration in this solution equal 5,01 × 10^-12 mol/l.
