Increasing the diversity within your "gut" can be achieved by consuming probiotics from fermented foods and beverages such as sauerkraut and kefir. Kombucha is a tea co-culture of bacteria and yeast (called a SCOBY) and ethanol is one of the products of this fermentation. Lindsey regularly drank kombucha for its perceived health benefits but was concerned about her blood alcohol level. When drinking kombucha, Lindsey's maximum blood alcohol concentration (BAC) reached 0.9 mg/100mL of blood. Given that the initial half-life for ethanol in the body is 40 minutes, what will be Lindsey's BAC after one hour (60 minutes)?A solution of chloroform (CHCl3) and acetone((CH3)2CO) exhibits a negative deviation from Raoult's law.This result implies that:W. chloroform-chloroform and acetone-acetone interactions are stronger than chloroform-acetone interactions.X. chloroform-chloroformand acetone-acetone interactions are weaker than chloroform-acetone interactions.Y. acetone-acetone interactions are stronger than chloroform-chloroform interactions.Z. acetone-acetone interactions are weaker than chloroform-chloroform interactions. only X is true W and Y are true only W is true X and Z are true only Y is true
