Must undergo addition because they have easily broken π bonds. rule states in the addition of hx to an unsymmetrical alkene, the h atom bonds to the less substituted carbon atom. are unsaturated hydrocarbons because they have fewer than the maximum number of hydrogen atoms per carbon. have good leaving groups and therefore readily undergo substitution and elimination reactions. in hydroboration, the boron atom bonds to the substituted carbon.

if you're asking what comes out, it's steam.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
