The substance would be sodium nitrate, to figure this out all you need to do is read each sentence carefully and see if whatever the lab technician notices happening to the substance does it match with any of the substances listed in the table, if it does not match, any one description we can eliminate that compound as a choice. Carry this method of elimination basically until you come to the last sentence. Since the substance melts at temperature above the melting point, it can't be potassium chromate as it would change state at a temperature of 974 degrees Celsius, not high of temperature for the change, as the oven is at 450 degrees Celsius only.

Given the information you now know, what is the effect of hyperventilation on blood pH?pH? During hyperventilation, the rapid in

Ksju [112]

Answer:

When hypercapnia processes occur, where the concentration of carbon dioxide gas increases in the blood, the protonization of the blood increases, this means that the H + ions increase in concentration, thus generating metabolic acidosis.

This metabolic acidosis is regulated by various systems, but the respiratory system collaborates by generating hyperventilation, to increase blood oxygen pressures, decrease CO2 emissions, and indirectly decrease acidity.

Explanation:

This method of regulating the body is crucial, since the proteins in our body will not be altered if they do not happen.

The enzymes, the red globules, and many more fundamental things for life ARE PROTEINS, that in front of acidic media these modify their structure by denaturing themselves and ceasing to fulfill their functions. This is the reason why it seeks to neutralize the blood pH when it comes to an increase in CO2.
