What effect does rapid exhalation of CO2 during exercise have on the concentration of H2CO3 in the blood?
lubasha [3.4K]
<span>Humans breathe in oxygen and breathe out carbon dioxide.During the process of breathing, humans convert sugar into energy. Carbon dioxide is a waste product of this process. Carbon dioxide is released into the blood, travels to the lungs and is exhaled. Because carbon dioxide is a weak acid, the more carbon dioxide in the blood, the more acidic the blood becomes.</span>

What stresses will shift the reaction to increase the products
AveGali [126]

Answer:

Change in molarity, temperature, volume/pressure depending on the conditions given

Explanation:

It really depends on the type of a reaction, however, we may apply general trends and see every possibility:

  • if we increase the concentration of products, then, according to the principle of Le Chatelier, the equilibrium will shift toward the formation of products;
  • if we have an endothermic reaction, increasing heat will lead a shift to the right and toward formation of products, since heat might be considered a reactant as well;
  • if we have an exothermic reaction, removing heat/decreasing temperature will lead to an increase in products, as we're removing one of our products, heat, and system will try to rebuild the amount of heat lost forming the other products as a result as well;
  • if we have gaseous substances in a reaction, an increase in pressure will shift the equilibrium to the right if we have a greater amount in moles of reactant gases compared to products, this is also known as a decrease in volume;
  • if we have gaseous substances in a reaction, a decrease in pressure will shift the equilibrium to the right if we have a greater amount in moles of product gases compared to reactants, this is also known as an increase in volume.

The​ half-life of the radioactive element unobtanium dash 53 is 20 seconds. if 32 grams of unobtanium dash 53 are initially​ pre
Lelu [443]
when the half-life is the amount of time which the radioactive isotopes need to

be in half.

So when w start with 32 g of unobtanium 53 so :

1- after 20 sec the number of grams remain = 32/2

                                                       = 16 g

2- and after 40 sec the number of grams remain

16 g will cut in half:

= 16 / 2 

= 8 g

3- and after 60 sec the number of grams remain

8 g will cut in half:

= 8g /2

= 4 g

4- and after 80 sec the number of grams remain

4 g will cut in half:

= 4 g /2

 = 2 g

5-after 100 sec the number of grams remain

2 g will cut in half :

     = 2g /2 

     = 0 g

after 100 sec there are no grams remain
