Answer: compound
Explanation: because the hydrogen molecules and the oxygen molecules are chemically bonded together unlike in a mixture
Answer:
Its existence was determined by an English scientist studying nature.
Its existence was established after the invention of the microscope.
Explanation:
I know because atoms are made up by a scientist study chemicals while trying to learn about atoms as well.
Answer : Linear
Explanation : Hydrogen Cyanide (HCN) when drwan in the Lewis diagram shows carbon atom at the center with no lone electron pairs.
The carbon and nitrogen atoms are bonded through a triple bond which counts as "one electron pair".
The molecule has two electron pairs in all and appears to be linear.
Also, according to the VSEPR theory; the electron clouds on atoms around the carbon will try to repel each other.
They will get pushed apart, which gives HCN molecule a linear molecular geometry or shape.
The bond angle that is developed will be 180 degrees since it has a linear molecular geometry of HCN. The hybridisation observed in this molecule is SP.

As you add more acid to the solution the amount of dissociation increases to compensate for it. But since the acid is weak, it will never have more ions dissociate than are in the concentrated solution being added. % ionization is the concentration of dissociated H+ ions divided by the initial concentration of the weak acid.
% ionization = [H+] / [weak acid] x 100%
As you increase the concentration of the weak acid, the numerator increases more than the denominator so the percentage goes down.
