Which of the statements below correctly describes the chair conformations of trans-1,4-dimethylcyclohexane? a. the higher energy chair conformation contains one axial methyl group and one equatorial methyl group. b. the lower energy chair conformation contains one axial methyl group and one equatorial methyl group. c. the two chair conformations are of equal energy. d. the higher energy chair conformation contains two axial methyl groups. e. the lower energy chair conformation contains two axial methyl groups.

D. The higher energy chair conformation contains two axial methyl groups.

Explanation:

The diaxial trans-1,4-dimethylcyclohexane has the highest energy (the least stable) and the diequatorial chair conformation has the lowest energy (the most stable).

The diaxial conformation has a higher energy due to the interaction between the methyl groups.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
