What do u mean by H+ ion?
Write a balanced chemical reaction for the formation of "soap scum" from a mixture of soap and "hard" water
Depict the structures of both of these molecules as well as give a brief explanation why the molar absorptivities of these two species would be expected to be similar.
When 1 mol of HF is added to 1kg of water, the freezing point decreases by 1.9 C, but when 1 mol of HBr is added, the freezing point decreases by 3.7 C. Which is more highly separated into ions, HF or HBr
N2O4+ 2 N2H4= 3 N2 + 4 H2O, Determine the limiting reactant and the mass in grams of nitrogen that can be formed from 50.0g N2O4 and 45.0g N2H4. The molar masses are as follows: N2O4=92.02g/mol, N2H4=32.05g/mol.
So we did a preparation of t-pentyl Chloride experiment in class the other day using t-pentyl alcohol, HCL, Aqueous sodium Bicarbonate, and calcium chloride as the drying agent.
A very long insulating cylindrical shell of radius 6.70cm carries charge of linear density 8.60Nc spread uniformly over its outer surface.
If one uses benzaldehyde rather than p-nitrobenzaldehyde in the aldol reaction the yield is extremely low, if it works at all. Offer an explanation for this result.
A solution of H2SO4 has a concentration of 0.175M. What is the pH of this solution. What is the concentration of hydroxide
Calculate the theoretical yield of aspirin obtained when 2.0 g of salicylic acid and 5.0 mL of acetic anhydride (density = 1.08 g/mL) 2. if 1.9 g of asprin were obtained in this experiment, what would be the percent yield
how does the strngth of the attraction between water molecules and sodium and chloride ions compare with the strength
A product has glycerol Molecular weight=92. The product contain 25% by weight glycerol and has a void fraction of ~70%, and a density of 1g/cm^3. Find its molar concentration
the sulfur is converted into sulfur dioxide gas.The sulfur dioxide reacts with solid calcium oxide to form solid calcium sulfite
