A shopping mall wanted to determine whether the more expensive “Tough Stuff" floor wax was better than the cheaper “Steel Seal” floor wax at protecting its floor tiles against
scratches. One liter of each grade of floor wax was applied to each of the 5 ¢st sections of the
main hall of the mall. The test sections were all the same size and were covered with the
same kind of tiles. Five other test sections received no wax. After 3 weeks, the number of
scratches in each of the test sections was counted. what is the experimental variable?

Fossil fuels are organic compounds that are made from

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
