Correct Answer - C Oxygen is absorbed in Pyrogallol solution.

Correct Answer - C A chemical equation gives us the quantitatives information about relative number of moles of the reatants and products involved in the reaction

Correct option is C) 4 : 3

Anhydrous gypsum `(CaSO_4)` when heated `1200^(@)`C decomposes slightly. `2CaSO_4overset(1200^(@)C)iff2CaO+2SO_2+O_2` However, to get quantitative yield of `SO_2` anhydrous gypsum is heated with coke, when calcium sulphide is first formed. `CaSO_4+2CtoCaS+2CO_2uparrow` On...

Correct Answer - C `d_(H - F) = 0.37 + 0.72 - 0.09 |4 - 2.1|` `= 1.09 - 0.17` `= 0.92 Å`

Option : c. Colour

Correct Answer - C When CAN react with R-OH there is no redox. `C_4H_9OH+underset("CAN (a yellow solid)")((NH_4)_2[Ce(NO_3)_6])to[Ce(NO_3)_5(n-C_4H_9O)]^(2-)` Wine red complex `NH_4^+` ion present as spectators and so not partcipate.

Correct Answer - C See the determination of the structure of organic compound .

Correct Answer - A As it provides `NH_(4)^(+)` ions which suppresses the ionisation of `NH_(4)OH` so that only the group `3^(rd)` cations are precipitated as hydroxides because of their low solubility...

Correct Answer - B Noise pollution is a physical form of pollution that affects the receiver directly affecting the nervous system which result into various disorders in humans. dB (decibel) is...
