Iron reacts with steam to form iron oxide and hydrogen gas.

-Zn is a reducing agent, HCl is an oxidizing agent. -the zinc is oxidized

Cast iron + haematite = wrought iron

Pre-heated air at about 600ºC is blown into the furnaces from the bottom through the tuyeres.

Carboxylic acids and enols react with sodium bicarbonate to liberate carbon dioxide. E,g CH\(_3\)COOH

An alkene is produced when dehydration of alcohol is performed. Alcohol dehydration is an example of an elimination reaction which is quite the opposite of substitution reaction and addition reaction. The products of the dehydration of a primary alkanol are water and an alk-1-ene (1-alkene). Butanol gives a mixture of but-1-ene and but-2-ene when dehydrated.

Straight-chain hydrocarbon molecules that contain only singly-bonded carbons are called alkanes. When naming these molecules, the final syllable in their name is "ane." Find and name the longest continuous carbon chain. Identify and name groups attached to this chain. Number the chain consecutively, starting at the end nearest a substituent group. Designate the location of each substituent group by an appropriate number and name.

Alkanes are very useful as fuels.

Isomers of Butene: are But-1-ene, But-2-ene, 2-Methylpropene or 2-methylprop-1-ene

Calcium ammonium nitrate or CAN, also known as nitro-limestone or nitrochalk, is a widely used inorganic fertilizer.

Terminal alkynes react with Tollens reagent (ammoniacal silver nitrate solution) to form silver alkynides as a white precipitate, whereas internal alkynes do not react with Tollens reagent.

If you shake an alkene with bromine water (or bubble a gaseous alkene through bromine water), the solution becomes colourless. Alkenes decolourise bromine water.

It is a graph that represents the force that acts on a body in a certain amount of time. Force on the object is represented by the y-axis and time taken by the object is represented by the y axis. The area under the curve indicates the impulse, the change in momentum that the object undergoes.

The kinetic-molecular theory of gases assumes that ideal gas molecules: (1) are constantly moving; (2) have negligible volume; (3) have negligible intermolecular forces; (4) undergo perfectly elastic collisions; and (5) have an average kinetic energy proportional to the ideal gas's absolute temperature.

Archimede's Principle states that a body immersed in a fluid experiences an upthrust equal to the weight of the fluid displaced, and this is fundamental to the equilibrium of a body floating in still water.
