Is the glue recipe in "Romy and Michele's High School Reunion" factually based? Here's the quote from the movie:
"Ordinarily when you make glue first you need to thermoset your resin and then after it cools you have to mix in a Poxide which is really just a fancy schmancy name for any simple oxygenated adhesive, right? And then I thought maybe, just maybe, you could raise the viscosity by adding a complex glucose derivative during the emulsification process and it turns out I was right."

I can't get these type of problems. I need these in the most simplistic terms possible please. Thanks so much!!!!!

Calculate the volume of .23M sulfuric acid that would be needed to neutralize 146 mL of a 1.72 M aqueous ammonia solution. The equation for the reaction is H2SO4 + 2 NH3 --> 2 NH4 +SO4-2


Calculate the concentration of an aqueous KCl solution if 584 mL of the solution gives 16.9 g of AGCl when treated with excess AgNO3. The equation for the reaction is
KCl + AgNO3 --> AgCl + KNO3

A salt solution is evaporated to dryness. If 51.7 g of the solution leaves 1,725 mg of dry salt, what is the percent concentration (w/w) of the salt in the solution?
Thanks so much for any help!

Can someone give me a step by step way to figuring this type of problem: Calculate the volume of 1.60 M NaI that would be needed to precipitate all of the hg+2 ion from 52 ml of a .78 M hg(No3)2. The equation for the following reaction is 2 naI + Hg(No3)2--> HGI2 +2 NaNO3
