Formic acid, HCOOH, the simplest carboxylic acid, is used in the textile and rubber industries and is secreted as a defense by many species of ants (family Formicidae). Calculate the percent dissociation of 0.38 M HCOOH.
Calculate the equilibrium concentration of HC2O4- in a 0.20 M solution of oxalic acid.
The initial pH of chloroacetic acid is 1.90, (which I found from using the quadratic equation to find x in a RICE table because I was given the initial concentration of 0.124M and told to find the pH of a 10.0 mL solution.)
Problem- A temperature rise from 27.0 degrees C to 42.0 degrees C for a 0.0487 kilogram sample of pure lead required 93.5 Joules of heat. Calculate the specific heat of lead.
an antacid, contains CaCO3. If Tums is added to 20.0mL of 0.400 M HCl solution, how many grams of CO2 gas are produced?
A balloon filled with helium gas at 20C occupies 2.91 L at 1.00 atm. The balloon is immersed in liquid nitrogen at -196C, raising the pressure to 5.20 atm.
Calculate the adiabatic flame temperature if one mole of CH4(g) is burned in two moles of O2(g) at an initial temperature of 298 K. Assume that the combustion occurs at constant pressure according to the reaction
Question- A reaction rate is 6.93x10^-3 at 10C. If you raise the temperature by 30C what approximately is the new reaction rate
How can one decompose superabsorbent polymers? That is how can one make the dry crystals smaller?
a student purified a 500-mg sample of phthalic acid by recrystallization from water. the published solubility of
Carotene is a tetraterpenoid consisting of eight isoprene units bonded in head-to-tail as well as tail-to-tail fashion and cross-linked to form six-member rings at either end. Desire the bond formed by tail-to-tail linkage of the isoprene units.
Why is it impossible to know both the position and velocity of an atom (i.e. electron). It states this in the Heisenberg uncertainty principle...but why
