What is a Benedict solution?

Answers

Answer 1
Answer: Benedict's solution, deep-blue alkaline solution used to test for the presence of the aldehyde functional group, - CHO. The substance to be tested is heated with Benedict's solution; formation of a brick-red precipitate indicates presence of the aldehyde group. Since simple sugars (e.g., glucose) give a positive test, the solution is used to test for the presence of glucose in urine, a symptom of diabetes. One liter of Benedict's solution contains 173 grams sodium citrate, 100 grams sodium carbonate, and 17.3 grams cupric sulfate pentahydrate. It reacts chemically like Fehling's solution; the cupric ion (complexed with citrate ions) is reduced to cuprous ion by the aldehyde group (which is oxidized), and precipitates as cuprous oxide, Cu2O

How many degrees Celsius is 871.09 Kelvin? Round your answer to two decimal places.

Answers

To convert Kelvin to Celsius, you need to subtract 273.15 from the given value. Let's perform the conversion:

871.09 Kelvin - 273.15 = 597.94 degrees Celsius

Therefore, 871.09 Kelvin is approximately equal to 597.94 degrees Celsius when rounded to two decimal places.

The temperature of 871.09 Kelvin as stated in the question is approximately -101.06 degrees Celsius.This is obtained by the standard result.

Temperature is often measured in two main scales, Kelvin (K) and Celsius (°C). To convert from Kelvin to Celsius, you need to subtract 273.15 from the given temperature in Kelvin.

This adjustment accounts for the fact that 0 Kelvin (absolute zero) is the point at which all molecular motion theoretically stops, while 0 degrees Celsius is the freezing point of water.

In this case, for the temperature of 871.09 Kelvin, the conversion is as follows:

The temperature in Celsius = 871.09 K - 273.15 ≈ -101.06°C.

This means that a temperature of 871.09 Kelvin is approximately equivalent to -101.06 degrees Celsius. It's important to note that Kelvin is an absolute temperature scale, where 0 K represents absolute zero, while Celsius is a relative scale with 0°C corresponding to the freezing point of water at standard atmospheric pressure.

What is glucose ?

A basic sugar, glucose has the chemical formula C6H12O6. The most prevalent monosaccharide, a type of carbohydrate, is glucose.

The primary form of sugar in the blood, glucose serves as the body's cells' main source of energy. Glucose can be produced by the body from other chemicals, or it can be obtained from the meals we eat. The bloodstream carries glucose to the cells. Insulin is one of many hormones that regulate blood glucose levels.

The brain is the most energy-hungry organ in the body and uses half of the body's sugar energy due to its abundance of nerve cells, or neurons. Thinking, memory, and learning are all tightly correlated with blood glucose levels and how effectively the brain uses this substance.

Thus, a homopoloymer of glucose is corn starch.
