3. Why was it necessary to heat the test tube in order for a chemical reaction to occur?

What is the work done by the electric force to move a 1 c charge from a to b?

[07.06] which of the following chemical reactions is an oxidation-reduction reaction? (2 points) wo3 + 3h2 yields w + 3h2o kno3 + licl yields lino3 + kcl caso4 + 2nacl yields na2so4 + cacl2 mg(no3)2 + 2hbr yields mgbr2 + 2hno3

What is the difference between a weak and strong base? only some of the molecules of a weak base dissociate to produce hydrogen ions when mixed with water, but all of the molecules of a strong base dissociate to produce hydrogen ions. strong bases result in the production of hydronium, while weak bases produce hydroxide ions. only some of the molecules of a weak base dissociate to produce hydroxide ions when mixed with water, but all of the molecules of a strong base dissociate to produce hydroxide ions. strong bases react with acids to produce water, but weak bases do not react at all.
