For two ionic solids, `CaO` and `KI`, which of the following statements is false?A. Lattice enthalpy of `CaO` is much higher than that of `KI`.B. `CaO` has high melting point.C. `KI` has low melting point.D. `KI` is soluble in benzene.
As the nuclear charge increases from neon to calcium, the orbital energiesA. IncreaseB. Increases very rapidlyC. increases very slowlyD. Fall
A compound `(A)` on heating in Busen flame imparts brick red colouration. `(A)` on heating gives `CO_(2)` gas and a residue `(B)`. The residue `(B)` when treated with water gives `(c )`. On passing an excess of `CO_(2)` through `(C )` in water, a clear solution `(D)` is obtained. On boiling `(D)`, compound `(A)` is reformed. Residue `(B)` isA. `CaO`B. `CaO_(2)`C. `SrO`D. `BaO`
A metal `M` readily forms water soluble `MSO_(4)` water insoluble `M(OH)_(2)` and oxide `MO` which becomes inert on heating. The hydroxide is soluble in `NaOH`. Then `M` is:A. `Be`B. `Mg`C. `Ca`D. `Sr`
Two metals `(A)` and `(B)` belong to the same group of the periodic table. Metal `(A)` forms and insoluble oxide but a soluble sulphate, metal `(B)` forms a soluble oxide but an insoluble oxide but an insoluble sulphate. Both metals `(A)` and `(B)` form hydroxides which are soluble in alkalis. `(A)` and `(B)` areA. `Ba` and `Mg`B. `Na` and `K`C. `Mg` and `Ba`D. `K` and `Rb`
Which of the follwing forms covalent compound?A. `Be`B. `Mg`C. `Ca`D. `Sr`
`CaC_(2)` reacts with water to giveA. MethaneB. EthaneC. EthyleneD. Acetylene
`Be_(2)+H_(2)OrarrBeO+X` `CaC_(2)+H_(2)OrarrCa(OH)_(2)+Y` `Mg_(2)C_(3)+H_(2)OrarrMg(OH)_(2)+Z` Identify `(X),(Y)` and `(Z)`.
On treatment with cold water, an element `(A)` reacted quietly liberating a colourless, odourless gas `(B)` and a basic solution `(C )`. Lithium reacted with `(B)` yielding a solid product `(D)` which effervesced with water to give a stongly basic solution `(E)` and gas `(F)`. When `CO_(2)` was bubbled through solution `(C )`, initially a white ppt. `(G)` was formed, but this redissolved forming solution `(H)` when more `CO_(2)` was passed, precipitate `(G)` effervesced when moistened with conc `HCl` and gave a brick red colouration to the bunsen flame. When `(G)` was heated with carbon at `1000^(@)C`, a caustic white compound `(I)` was formed, which when heated with `N_(20` at `1000^(@)C` gave a solid `(J)` of some commercial importance. Identify `(A)` to `(J)` and explain the reactions.
Limestone is a naturally occuring form of calcium carbonate. It is used as building materials and also for manufacture of other building materials such as portland cement. It is used for the production of quickline and slaked lime which have wide applications in chemical, metallugical and construction industry. The pure `CaCO_(3)`, called precipitated calcium carbonate, is used extensively as filler, providing bulk to materials such as paint, plastics, printing links and rubber. it is also used in toothpastes, cosmetics and antacids. Quicklime and slaked lime are the cheapest and the most widely used bases for neutralising unwanted acids. Lime is used to neutralise acidic soils. An important application of quicklime is in air pollution control for the removal of `SO_(2)` in electric power plants. slaked lime is used in the manufature of other alkalis and bleacing powder, in sugar refinig, in tanning hide and in water softening. Chemical compound `(A)` is used to remove temporary hardness from water. It reacts with `Na_(2)CO_(3)` to generated caustic soda. when `CO_(2)` is passed through `(A)` it turns cloudy. What is `(A)`?A. `CaCO_(3)`B. `Ca(HCO_(3))_(2)`C. `Ca(OH)_(2)`D. `CaCl_(2)`
