Pentane with molecular formula C5H 12, exists in three Isomeric forms. One shows linear carbon chains, another has one -CHg groups present on the third carbon atom, and the third has two -CHa
groups present on the second carbon atom. What types of Isomers are these?
OA
Geometric Isomers
O B. Structural Isomers
Oc
Halotropic Isomers

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

1) which of the following is the best example of a physical change? a) sugar dissolving in tea b) firefly glowing 2) in the combustion of ethane, what is/are the reactants? c2h6 + o2 ==> co2 + h2o a) c2h6 and o2 b) co2 and c2h6
