Fluorine reacts with ice and results in the change.
`H_(2)O(s)+F_(2)(g)toHF(g)+HOF(g)`
Justify that this reaction is a redox reaction.

One mole of H_(2)O and one mole of CO are taken in 10L vessel and heated to 725K . At equlibrium 40% of water (by mass) reacts with CO according to the equation. H_(2)O(g)+CO(g)hArrH_(2)(g)+CO_(2)(g) Calculate the equilibrium constant for the reaction.

Burning of coal is reprsented as C_((s))+O_(2(g))toCO_(2(g)) . The rate of this reaction is increased by

The formation of water from H_(2(g)) and O_(2(g)) is an exothermic reaction because

Justify that the reaction : 2 Na(s) + H_(2) (g) rarr 2NaH (s) is a redox change.

In a reaction vessel, 100 g H_(2) and 100 g Cl_(2) are mixed and suitable conditions are provided for the reaction: H_(2(g))+Cl_(2(g))to2HCl_((g)) The amount of HCl formed in this reaction (at 100% yield) will be
