Displacement reaction
Hydrogen sulphide explodes when it is mixed with oxygen.
oxygen = H2O water, sulphur = hydrogen sulphide Only one element can form with hydrogen, and that is hydrogen itself.
A reaction with oxygen, water, hydrogen sulphide, acids, bases
silvers turn black due to the reaction of sulphur present in hydrogen sulphide from air. --- Tarnish is silver oxide (rust) caused by a chemical reaction of oxygen and hydrogen sulphide with the surface of the silver. Unlike iron, silver will not rust in air absent of hydrogen sulphide.
Hydrogen bonding exists between hydrogen and oxygen in water, becuase of the huge electronegativity difference between oxygen and hydrogen. This arises, due to the huge electron affinity of oxygen. Such interaction is not possible between carbon and hydrogen, as athe carbon is not as electronegative as oxygen.
this because the chemical reaction between Oxygen & Hydrogen obviously the Hydrogen bonds between Oxygen & Hydrogen.
The bond between hydrogen and oxygen is covalent.
Although both molecules are polar and have similar masses, the O-H bond in water is highly polar, producing a dipole movement in the overall molecule towards O. The S-H is also polar and produces a dipole movement towards S, but it is not as strong a separation of charge as that produced by O-H. This results in H20 molecules being more strongly attracted to each other by Hydrogen bonding, than H2S molecules which are attracted to each other due to only dipole-dipole attraction. Stronger attraction between molecules means it takes more energy to separate them into the gas phase, making it have a higher boiling point.
Hydrogen + oxygen → water2H2 + O2 → 2H2O
Covalent
The attraction of hydrogen and oxygen atoms in a compound is referred to as a hydrogen bond. The bond between hydrogen and oxygen is what makes up water, also known as H2O.
