Explanation:
25. Binary ionic compounds: They are known as the compounds which contains a cation formed from a metal and an anion formed from a non-metal or a polyatomic anion. For example : Barium sulfate
Ba : +2 ( metal of group II-A)
: -2 ( sulfate)
These two ions combine to form a binary ionic compound having formula
Binary Molecular compounds: They are known as the compounds which contain two or more non-metals that are bonded covalently. In these compounds, no ions are present because the electrons are shared by the atoms. Examples are: : phosphorous trichloride
: sulfur dioxide
26. The general chemical formula for an acid is HX where H is the hydrogen and X is the non-metal or polyatomic ions. Examples of acids are:
HF : Hydrofluoric acid
: Sulfuric acid
Omg what grade are you in lol
Answer: distilation, because they have different boling points.
The three isomers of pentane and their normal boling points are:
pentane, b.p. approx. 36°C
iso pentane, b.p aprox 28°C
neo pentane. b.p. approx. 10°C
Those differences in their boiling points make possible to separate them by distillation.
Answer:
element n weighs approximately 14.0067 grams
Ok I’m not completely confident on this but I think it’s when there are only little amounts of the gas
