How many molecules of sucrose c12h22o11 are there in 454 grams of sucrose

c(C12H22O11) = 342.3 g/mol

454 g / (342.3 g/mol) = 1.326 mol

1.326 mol * 6.022*10^23 molecules/mol = 7.985·10^23 molecules

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

explanation:

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
