Match the common name of chemicals in Group – 1 with their chemical formulae in Group – 2.
The correct combination is:
Match the common name of chemicals in Group – 1 with their chemical formulae in Group – 2.
The correct combination is:
Show Hint
- P–III, Q–II, R–I
- P–III, Q–I, R–II
- P–II, Q–III, R–I
- P–II, Q–I, R–III
The Correct Option is C
Solution and Explanation
Gypsum is chemically calcium sulfate dihydrate, represented by CaSO\(_4\)·2H\(_2\)O.
Thus, P matches with II.
Q → Dolomite → CaCO\(_3\)·MgCO\(_3\) (III)
Dolomite is a double carbonate of calcium and magnesium.
Its correct formula is CaCO\(_3\)·MgCO\(_3\), so Q matches with III.
R → Triple superphosphate → Ca(H\(_2\)PO\(_4\))\(_2\) (I)
Triple superphosphate is produced by treating phosphate rock with phosphoric acid.
Its major component is monocalcium phosphate, Ca(H\(_2\)PO\(_4\))\(_2\).
Thus, R matches with I.
So the correct matching is:
P–II, Q–III, R–I, which corresponds to option (C).
Top Questions on Inorganic chemical industries
- Methane combusts with air in a furnace as \( \text{CH}_4 + 2\text{O}_2 \rightarrow \text{CO}_2 + 2\text{H}_2\text{O} \). The heat of reaction \( \Delta H_\text{r} = -880 \, \text{kJ/mol CH}_4 \), and is assumed to be constant. The furnace is well-insulated, and no other side reactions occur. All components behave as ideal gases with a constant molar heat capacity \( c_p = 40 \, \text{J mol}^{-1} \, \text{°C}^{-1} \). Air may be considered as 20 mol\% \( \text{O}_2 \) and 80 mol\% \( \text{N}_2 \). The air-fuel mixture enters the furnace at \( 50 \, \text{°C} \). The methane conversion \( X \) varies with the air-to-methane mole ratio, \( r \), as: \[ X = 1 - 0.1e^{-2(r-r_s)}, \, \text{with} \, 0.9r_s \leq r \leq 1.3r_s, \] where \( r_s \) is the stoichiometric air-to-methane mole ratio. For \( r = 1.05r_s \), the exit flue gas temperature in \( \, \text{°C} \), rounded off to 1 decimal place, is:

Questions Asked in GATE CH exam
An ideal monoatomic gas is contained inside a cylinder-piston assembly connected to a Hookean spring as shown in the figure. The piston is frictionless and massless. The spring constant is 10 kN/m. At the initial equilibrium state (shown in the figure), the spring is unstretched. The gas is expanded reversibly by adding 362.5 J of heat. At the final equilibrium state, the piston presses against the stoppers. Neglecting the heat loss to the surroundings, the final equilibrium temperature of the gas is __________ K (rounded off to the nearest integer).
