A sample of an ideal gas with initial pressure P and volume V is taken through an isothermal process during which entropy change is found to be \[\Delta S\]. The universal gas constant is R. Then, the work done by the gas is given by
\[PB{{r}_{2}}C{{l}_{3}}\] can exhibit geometrical isomerism. Geometrical isomers are as follows : Which of the above mentioned geometrical isomer(s) has/have no dipole(s)?
The structure of an organic compound which on oxidation gives an acid that gives a mono-substituted product on nitration with \[HN{{O}_{3}}\] and \[{{H}_{2}}S{{O}_{4}}\], is
When hydrogen peroxide is treated with a cold acidified \[{{K}_{2}}C{{r}_{2}}{{O}_{7}}\] solution containing ether, a blue colour is obtained. This is due to
A mixture contains equimolar quantities of carbonates of two bivalent metals. One metal is present to the extent of 13.5% by weight in the mixture and 2.58 g of the mixture on heating leaves a residue of 1.35 g. What percentage by weight of the other metal is there?
