Answer:
As the level of carbon dioxide in the blood increases, more H+ is produced and the pH decreases. This increase in carbon dioxide and subsequent decrease in pH reduce the affinity of hemoglobin for oxygen. The oxygen dissociates from the Hb molecule, shifting the oxygen dissociation curve to the right.
Answer:
The correct answer would be the third choice.
Homo-genesis mixtures are the same in composure, and will be hard to break apart other then with chemical means.
Hope this helps!
In the first box, you should draw a chicken. In the second box, you should draw a cow <u>or</u> <u>a</u> horse.
I hope it helps you!!!! :D

Na2C03 10H2O is hydrated sodium carbonate salt or sodium carbonate with water of crystallisation.
<u>Explanation</u>:
- The water atoms which are a piece of the structure of a precious stone of salt are called Water of crystallization.
The regular name and synthetic equation of an industrially significant compound which has ten water particles is Sodium Carbonate [washing soda]
Na2CO3.10H2O
Preparation:
-
A cold and Concentrated Solution of Sodium chloride is responded with Ammonia and Carbon dioxide to get Sodium Hydrogen Carbonate.
NaCl +NH3 +H2O+CO2 - >NaHCO3 +NH4Cl
-
Sodium Hydrogenarbonate is isolated by filtration, dried and warmed. On warming, sodium hydrogen carbonate deteriorates to frame Sodium carbonate.
2NaHCO3 - > Na2CO3 + CO2 + H2O
-
Anhydrous sodium carbonate is broken down in water and to get 10 atoms of water of crystallization.
Na2CO3+10H2O - >Na2CO3.10H2O
Imagine we have <span>mass of solvent 1kg (1000g)
According to that: </span>
