This reaction is known as
Acidic Cleavage of Ether.
Ether when treated with strong acid like
HI, the oxygen atom of ether picks the proton making a positive charge on oxygen. The
Iodide conjugate base formed acts as a
nucleophile and attacks on the carbon next to positive oxygen and forms
Alkyl Halide. This is a type of
SN² reaction. The complete reaction with missing atoms, charges and arrows is shown below,
The Earth's gravitational force accelerates objects when they fall. It constantly pulls, and the objects constantly speed up.

Chemical compounds have chemically bonded molecules so that they exhibit different properties (i.e. chemical) compared to the individual molecules comprising the compound. Mixtures are simply the combinations of different molecules and compounds that are not chemically bonded together, and can therefore be separated by physical means. Mixtures usually retain the properties of its components. The hydrogen and oxygen molecules in a mixture do not form strong bonds between each other. The molecules of both gases are only contained in the same space or volume and the individual molecules retain their chemical properties.
A compound containing hydrogen and oxygen molecules exhibit different chemical (and even physical) properties compared to the individual molecules themselves.
Water for example, is a compound with 2 hydrogen atoms and 1 oxygen atom, chemically-bonded together. Hydrogen gas is highly flammable, water is not. Oxygen gas is an essential reagent for combustion (or burning) reactions, water is not.
Thus, throwing a lighted match to a gaseous mixture of hydrogen
and oxygen
would create fire, or even an explosion (since hydrogen is flammable and oxygen feeds the reaction). Throwing a match to water vapor
would not create fire.
