What does the above equation shows iq light reaction?

The reaction takes place at anode in H_2 - O_2 fuel cell is

Chloroform can be prepared by the reaction of C_2H_5OH with bleaching powder. In the above method, the reaction taking place

Explain any two methods of preparation of diborane. Write the reactions of B_2 H_6 with a) H_2 O b) CO. Give equations.

Refer to the given reaction . 2H_(2) O rarr 4H^(+) +O_(2) +4e^(-) Where does this reaction take place in the chloroplasts of plants ?

Write differences between Nutrition in autotrophs occurs when there is light and without light also. What is the difference between these two situations ? Differentiate the reactions that take place in presence of light and the reactions which do not require light in photosynthesis.

Aliphatic nucleophilic substitution mainly takes place by two mechanisms (i.e) SN^1 & SN^2 Primary halides mainly undergo by SN^2 mechanism and are favourable in polar aprotic solvents. SN^1 reactions takes place mainly by tertiary halide and are more favourable in polar protic solvents, In case of tertiary halides, E_1 comes competition to SN^1 reaction. Keeping in view of these general points, answer the following questions (+)C_6H_5CH(CH_3)Cl to (pm) C_6H_5CH(OH)CH_3 in which of the following solvents, the above reaction is most favourable

Y overset(Na)(larr) X overset(conc.H_2SO_4 . 413 K)(to) (C_2H_5)_2O What are X and Y in the above reactions ?

Magnesium is a valuable, light weight metal used as a structural material as well as in alloy hatteries and in chemical s . Although magnesium is plentiful in Earth s maire found in the sea water after sodium). There is about 1.3 8 of magnesium in every kilogram of se water. The process for obtaining magnesium from en water employs all three types of reaction Le precipitation, acid-base, and redox reactions Redox reaction takes place in the extraction of Mg :

The decomposition of N_(2)O_(5) in C Cl_(4) at 318K has been studies by monitoring the concentration of N_(2)O_(5) in the solution. Initially the concentration of N_(2)O_(5) is 2.33 mol L^(-1) and after 184 minutes, it is reduced to 2.08 mol L^(-1). The reaction takes placed according to the equation 2N_(2)O_(5)(g)to 4 NO _(2)(g) +O_(2)(g) Calculate the average rate of this reaction in terms of hours, minutres and seconds. What is the rate of proudction of NO_(2) during this period ?
