A researcher collected the data shown to see how the concentration of thiosulfate in water affects the reaction time with hydrochloric acid. Which conclusion can the researcher draw?

A
As concentration increases, reaction time decreases.

B
There is no obvious mathematical relationship.

C
As concentration decreases, reaction time decreases.

D
As concentration increases, reaction time increases.

In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. the solution was heated by burning natural gas in a bunsen burner to distill the ethanol that formed in the flask. during the distillation, the ethanol evaporated and then condensed in the receiving flask. the flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. during this experiment the following changes occurred. which of these changes involved a physical change and not a chemical change? check all that apply. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask

In numbering carbon atoms in the parent chain of a hydrocarbon, why would you number from right to left, rather than left to right
