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
Altitude, If this helped please 5 star me
Answer:
C
Explanation:
I just think it is the right answer :) Sorry if I am wrong..
Answer:density of an object can be determined by the total mass and buoyancy of the object
Explanation:
Answer:
For 6.50 mol NaOH - 1.44M.
For 6.50 g NaOH - C. 0.0361 M
Explanation:
For 6.50 mol NaOH.
Molarity = moles solute/L solution = 6.5 mol/4.5 L solution = 1.44 mol/L=1.44M
There is no such answer in given choices.
For 6.50 g NaOH
M(NaOH) = 23 + 16 + 1 = 40 g/mol
Molarity = 6.5g* 1 mol/40g *1/4.5L = 0.0361 mol/L = 0.0361 M
There is such answer. It is C.
