Answer:

Physical separation

Explanation:

  • Titration is a process in which we use a titrant, a solution of known concentration, and adding it to our analyte, a solution of unknown concentration. Using an indicator within the analyte solution lets us find the equivalence point, as indicator changes the color when all of the solute in the unknown solution reacted. We can then apply stoichiometry and find the molarity of the analyte. Hence, this is a process of determining molarity.
  • Combustion is a process in which we burn a substance in excess of oxygen, it produces new products.
  • Physical separation is a process to separate a mixture of several compounds into its individual components, usually based on different solubility, different boiling point or different density/polarity.
  • Chemical decomposition is a process in which we heat an insoluble substance to a high temperature and decompose it into separate new substances.

In Denver, Colorado the elevation is about 5,280 feet above sea level. Explain what potential effects this may have on the solub
Colt1911 [192]

Answer:

The solubility of the gaseous solute decreases

Explanation:

As we know, pressure decreases with altitude. This means that, at higher altitudes, the pressure is much lower than it is at sea level.

The solubility of a gas increases with increase in pressure and decreases with decrease in pressure.

Hence, in Denver, Colorado where the elevation is about 5,280 feet above sea level, a gaseous solute is less soluble than it is at sea level due to the lower pressure at such high altitude.

Leni [432]
Holding temperature and pressure constant <span>the most important feature in determining the phase of a given organic compound is pressure. ransfers of organic compounds between phases are controlled by molecular interactions (intermolecular bonding) in the two phases between which transfer is occurring. This is governed by temperature and pressure</span>

Please help: How do oxidation reactions help people with diabetes monitor their blood glucose levels? Thank you!!!
solong [7]

Answer:-

People with diabetes must monitor their blood glucose levels constantly.

Blood glucose levels are nowadays measured by the help of enzyme glucose oxidase. The enzyme glucose oxidase catalyzes the oxidation of glucose to gluconic acid.

By this way all of the glucose is measured at one time. At the same time hydrogen peroxide is produced.

The hydrogen peroxide reacts with a second color producing chemical. The concentration of the glucose can be related to the intensity of color produced
