Ethanol is highly toxic if it is consumed in large quantities. Although it is the second least toxic of the five alcohols discus

sed in this case, the ingestion of large quantities of ethanol is not safe. One serious problem with ethanol consumption is how the quantity is conveyed to the consumer. For example, American malt liquor can be sold in 23.5 fl. oz. (695 mL) cans and is 12% volume per volume (v/v) ethanol. Although these cans are labeled as containing multiple servings, many young people consider one can to be a single serving. Drinking two cans of this beverage can result in an accidental overdose of ethanol. Two cans may not seem like much until you do the math. In the previous question, you determined that the total volume of pure ethanol in a 695 mL can of American malt liquor is 83.4 mL. To better understand its significance, consider how this volume of ethanol compares with other alcoholic beverages. Calculate the total volume of ethanol in a standard 25.4 fl. oz (750 mL) bottle of liquor (e.g., whiskey, vodka, rum, etc.), which is typically 40% (v/v) ethanol. Enter your answer in milliliters. pure ethanol in liquor: mL Now calculate the total volume of ethanol in a typical 12 fl. oz (354.8 mL) can of light beer, which is 4% (v/v) ethanol. Enter your answer in milliliters. pure ethanol in light beer:

A significant MOE exists compared to developmental toxicity effect levels.

Blood alcohol levels from ABHS approximate consumption of non-alcoholic beverages.

No significant risk of developmental toxicity is expected from ABHS use.

Ethanol-based topical antiseptic hand rubs, commonly referred to as alcohol-based hand sanitizers (ABHS), are routinely used as the standard of care to reduce the presence of viable bacteria on the skin and are an important element of infection control procedures in the healthcare industry.

There are no reported indications of safety concerns associated with the use of these products in the workplace. However, the prevalence of such alcohol-based products in healthcare facilities and safety questions raised by the U.S. FDA led us to assess the potential for developmental toxicity under relevant product-use scenarios.

Estimates from a physiologically based pharmacokinetic modeling approach suggest that occupational use of alcohol-based topical antiseptics in the healthcare industry can generate low, detectable concentrations of ethanol in blood.

This unintended systemic dose probably reflects contributions from both dermal absorption and inhalation of the volatilized product.

The given question is incomplete. The image present in the question for Reaction A is attached below along with the answer.

Explanation:

Pyruvate molecule reacts with Coenzyme A in the presence of oxygen and it results in the formation of acetyl Coenzyme A and carbon dioxide.

The enzyme pyruvae dehydrogenase helps in catalyzing this reaction. As in this biochemical reaction NAD^{+} gets converted into NADH.

This reaction is shown in the image attached below.

8. A sample of potassium chlorate (KCIO,) was heated in a test tube and decomposed 2KC?(s) 302 (g) + 2KCIO, (s) The oxygen was c
dangina [55]

Answer:

Partial pressure of O_{2} in the gas was 733 torr and mass of KClO_{3} in the sample was 2.12 g.

Explanation:

a) Total pressure of gas = (partial pressure of water vapour)+(partial pressure of O_{2})

Here partial pressure of water vapour is 21 torr and total pressure of gas is 754 torr.

So, partial pressure of O_{2}= (total pressure of gas)-(partial pressure of water vapour) = (754 torr) - (21 torr) = 733 torr

b) Lets assume that O_{2} behaves ideally. Hence-

                                            PV=nRT

where P is pressure of O_{2}, V is volume of O_{2} , n is number of moles of O_{2} , R is gas constant and T is temperature in kelvin

here P = 733 torr = (733\times 0.001316)atm = 0.9646 atm

        V = 0.65 L, R = 0.082 L.atm/(mol.K), T=(273+22)K = 295 K

   So, n=\frac{PV}{RT}

                   = \frac{(0.9646 atm)\times (0.65 L)}{(0.082 L.atm/(mol.K))\times (295 K)}

                   = 0.0259 moles

As 3 moles of O_{2} are produced from 2 moles of KClO_{3} therefore 0.0259 moles of O_{2} are produced from (\frac{2\times 0.0259}{3}) moles or 0.0173 moles of KClO_{3}.

Molar mass of KClO_{3}= 122.55 g

So mass of KClO_{3} in sample = (0.0173\times 122.55)g

                                                                    = 2.12 g
