Calculate the concentration of sugar `(C_12H_22O_11)` in mol `L^-1` if its 20g are dissolved in water to make a final volume of 2L.

Give the oxidation number of C in C_12H_22O_11

The time for half-life period of a certain reaction A rarr Products is 1 h. When the initial concentration of the reactant A, is 2.0 mol L^(-1) . How much time does it take for its concentration to come from 0.50 mol L^(-1) to 0.25 mol L^(-1) , if it is a zero-order reaction?

In a reaction , 2Ato product, the concentration of A decreases from 0.5 mol L^(-1) to 0.4 mol L^(-1) in 10 minutes. Calculate the rate during this interval.

The molal freezing point constant of water is " 1.86 Km"^(-1) . If 342 g of cane sugar (C_(12)H_(22)O_(11)) is dissolved in 1000 g of water, the solution will freeze at

A 5% solution (by mass) of cane sugar (C_12 H_22 O_11) in water has a freezing point of 271 K. Calculate the freezing point of 5%. (by mass) solution of glucose (C_6 H_12 O_6) In water. Freezingpoint of pure water is 273.15 K.

Ethyl acetate is formed by the reaction between ethanol and acetic acid and equilibrium is represented as: 'CH_3 COOH_( )+C_2 H_5 OH_(l) hArr CH_3 COOC_2 H_5_(l)+H_2 O_(l)' i) Write the concentration ratio (reaction quotient), 'Q_c', for this reaction (note: water is not in excess and is not a solvent in this reaction) ii) At '293 K', if one starts with '1.00' mol of acetic acid and '0.18 mol' of ethanol, there is '0.171' mol of ethyl acetate in the final equilibrium mixture. Calculate the equilibrium constant. iii) Starting with '0.5' mol of ethanol and '1.0' mol of acetic acid and maintaining it at 293 ' K, '0.214' mol of ethyl acetate is found after sometime. Has equilibrium been reached?
