Chemosensitive area in brain is highly sensitive to:- 1 Na+, Cl- & O2 2 02 as well as CO2 3 CO2 & H+ ions 4 HCO3, CO2 & O2

(A) Phenols are acidic & react with alkalies like NaOH but do not react with Na_2CO_3 and NaHCO_3 solutions (R) CO_3^(-2) & HCO_3^- ions are less basic than phenoxide ion

Write balanced equations for reactions between (a)Na2 O2 and water (b) K O2 and water (c) Na2 Oand CO2

In the following equations Na_2CO_3 + xHCl to 2NaCl + CO_2 + H_2O the value of x is

Balance the equations : C_2H_4 + O_2 to CO_2 + H_2O

Balance the equations : C_2H_4+O_2 to CO_2 + H_2O

Choose the acidic oxides, basic oxides and neutral oxides from the following N O_2 , Na_2 ,O, CO_2 ,CO,S O_2 , H_2 O,MgO,CaO

Some chemical equations are given below 1) C+O_2 rarr CO_2 2) CH_4+2O_2 rarrCO_2+2H_2O 3) N_2+O_2 rarr NO 4)CaCO_3 rarr CaO+CO_2 5)H_2+I_2 rarr HI 6)Fe+HCl rarr FeCl_2+H_2 7 )CO_2+C rarr CO Which of these are balanced equations ?
