The buffer system which helps to maintain the pH of blood between 7.26 to 7.42 is
Tubular secretion helps to maintain a proper acid-base balance by removing one of the following from blood
Changes in CO2 and H+ ions concentration of blood are detected by
Effect of 2,3- DPG on the human blood is that :-
4g of mixture of Na_(2)CO_(3) and NaHCO_(3) on heating liberates 448 ml of CO_(2) at STP. The percentage of Na_(2)CO_(3) in the mixture is
Given below the simplified pathway of the circulatory system of man: Name the blood vessels labelled 1. 3. 6. and 7.
White blood cells help in (A) clotting of blood (B) transport of O2 (C) transport of CO2 (D) destroying harmful germs
Mixture of MgCO_(3) & NaHCO_(3) on strong heating gives CO_(2) & H_(2)O in 3 : 1 mole ratio. The weight % of NaHCO_(3) present in the mixture is :
The equations given below relate to the manufacture of sodium carbonate (molecular mass of Na CO_(3) = 106). NaCl+NH_(3)+CO_(2)+H_(2)O to NaHCO_(3) +NH_(4)Cl 2NaHCO_(3) to Na_(2)CO_(3)+H_(2)O+CO_(2) Question a and b are based on the production of 21.2 g of sodium carbonate b. To produce the mass of sodium hydrogen carbonate calculated in (a) what volume of carbon dioxide measured at STP, would be required?
