There are 0.31 mol in h3po4
Answer:
Explanation:
Sodium benzoate forms when benzoic acid reacts with sodium bicarbonate. Since benzoic acid is readily soluble in ether than water, the salt of benzoic is more soluble in water than in ether because it is ionic and very polar. water which is the lower layer will contain sodium benzoate.
After separating the lower layer, if acidified with Hcl,benzoic acid will be regenerated, it precipitates out as a result of its low solubility in water.
Answer:
Isotopes
Explanation:
Isotopes are the same element with different masses because of the different number of neutrons. Also, the element doesn't change. If we change the protons, the element will change and then it won't be an isotope. Hope it helps!
It's the number of Protons of that atom..
Answer:
It commonly ranges between 0 and 14, but can go beyond these values if sufficiently acidic/basic. pH is logarithmically and inversely related to the concentration of hydrogen ions in a solution. The pH to H + formula that represents this relation is: The solution is acidic if its pH is less than 7.
