Name a few solutions you come in contact with every day. What substances make up these solutions? What is the solvent and the solute
Ethylene, C2H4, and water react under appropriate conditions to give ethanol. The reaction is C2H4(g) + H2O(g) C2H5OH(g) An equilibrium mixture of these gases at a certain temperature
The concentration of hydrogen ions in a solution of 40.0 mM butanoic acid and 0.01 M NaCl. The ionization constant of butanoic acid is Ka = 1.52 × 10-5. Take the size of C3H7COO- to be 500 pm
indicate whether the signs of H and S are expected to be positive, negative or about 0. For each, indicate whether the process is always spontaneous, never spontaneous, spontaneous at high temperature or spontaneous at low temperature.
What data is collected in a titration? How would I be able to find what the volume of 0.10M HCl should be needed to titrate .136 g Na2CO3 according to the reaction equation:
a student dispensed 82mL sodium hydroxide(titrant) into the lemon juice(analyte) before the end point was reached. Estimate the analyte concentration, assuming that the acid in the lemon juice is monoprotic.
Draw structural formulas for all of the structural isomers of C4H10, C5H12 and C3H7Cl.
Question about Thermochemistry, Consider the reaction: H2(g) + Cl2(g) yields 2HCl(g) Change Heat = -184.6
