In which of the following reactions heat liberated is known as standard heat of formation of CO_(2) ?

Dihydrogen gas used in Haber's process is produced by reacting methane from natural gas with high temperature steam. The first stage of two stage reaction involves the formation of CO and H_(2) . In second stage , CO formed in first stage is reacted with more steam in water gas shift reaction. CO(g)+H_(2)OhArrCO_(2)(g)+H_(2)(g) If a reaction vessel at 400^(@)C is charged with an equimolar mixtureof CO and steam such that p_(CO)=p_(H_(2)P=4.0 bar, what will be the partial pressure of H_(2) at equilibrium ? K_(p)=10.1 at 400^(@)C

What are the uses of oxygen and CO_2 ?

When 2.4g of carbon reacted with X g of oxygen to form CO and CO_2, 50.4 kJ of heat was released and no reactant is left over. Standard heats of formation of carbon monoxide and carbondioxide are -110.5 kJ mol^(-1) and -393.5 kJ mol^(-1) respectively. Calculate X.

A certain compound (x ) shows the following reactions. (i) When KI is added to an aqueous suspension of X containing aceticacid, iodine is liberated. (ii) When CO_(2) is passed through an aqueous suspension of 'X', the turbidity transforms to a ppt. (iii) When a paste of (X ) in water is heated with ethylalcohol, a product of anaesthetic use is obtained. The anaesthetic obtained in the above, treated with silver powder to form the following.

Hydrogen bonding is said to be formed, -when sightly acidic hydrogen-atom attached to a strongly, electronegative fluorine, oxygen or nitrogen atom. is held with weak. electrostatic forces by the non-bonded pair of electrons of another atom. The co-ordination number of hydrogen in such cases is two. It acts as a bridge between two atoms, to one of which it is covalently bonded and to other attached through electrostatic forces, also called hydrogen bond. Though the hydrogen atoms in a methyl group are not polarised, if an electronegative group like chloro, carbonyl, nitro or cyano (in order to increase electronegativity) is attached to it, the C-H bond gets polarised due to the inductive effect and the hydrogen atom becomes slightly acidic resulting in the formation of weak hydrogen bonds. Though a weak bond the H-bond effects is large number of the physical properties of compounds some of which are - Boiling points of liquids - Solubility of polar compounds in polar solvents (containig H attached with strong electronegative atom) - Viscosity of liquids . Acidity Which of the following combinations can involve hydrogen bonding I) Mixture of KF and HF " " II) Mixture of CH_(3)COCH_(3) and CHCI_(3) III) Mixture of NH_(4) CI and H_(2)O" " IV) Mixture of CH_(3) and H_(2)O
