Which rule should be followed when naming binary acids

Answers

Here you are this will explain it it is one of my own persoal papers

Acids are divided into two groups: Binary and Oxyacids. NAMING BINARY ACIDS: The name of the binary acid consists of two words. The first word has three parts: the “hydro” prefix the root of the nonmetal element the “ic” ending The second word is always “acid” Examples: HCl = hydro chlor ic acid = hydrochloric acid HBr = hydro brom ic acid = hydrobromic acid HF = hydro fluor ic acid = hydrofluoric acid 2. NAMING OXYACIDS: These are more difficult to name because these acids have hydrogen, a nonmetal, and may have varying numbers of oxygen atoms. For example, H2SO5, H2SO4, H2SO3, and H2SO2 are all acids. How do we name them? To begin, we need a point of reference. Our reference point is this: The “ate” ions (sulfate, nitrate, etc) make the “ic” acids (sulfuric acid, nitric acid) Examples: SO4 2- = sulfate ion H2SO4 = sulfuric acid NO3 - = nitrate ion HNO3 = nitric acid Once we have our point of reference, the acid with one more oxygen than the -ic acid is called the per-_________-ic acid. The acid with one less oxygen then the -ic acid is called the ___________-ous acid. If the acid has one less oxygen than the -ous acid, it is called the hypo-____________-ous acid. Examples: H2SO5 = persulfuric acid HNO4 = pernitric acid H2SO4 = sulfuric acid HNO3 = nitric acid H2SO3 = sulfurous acid HNO2 = nitrous acid H2SO2 = hyposulfurous acid HNO = hyponitrous acid The KEY:

Make sure that a hydrogen is bonded with a nonmetallic element, like HBr, HCl, or HF.

Which of the isotopes is the most abundant isotope in the sample?Cd-106
Cd-108
Cd-112
Cd-114
Cd-116

Answers

Answer: Cd-112

Explanation: to find out the most abundant isotope, look at the weighted average on the periodic table. the one closest to it in mass is going to be the most abundant isotope. in this case, the weighted average of cadmium is 112.411, so the answer is Cd-112.

A 3.0 M HCl(aq) solution contains a total of(1) 3.0 grams of HCl per liter of water
(2) 3.0 grams of HCl per mole of solution
(3) 3.0 moles of HCl per liter of solution
(4) 3.0 moles of HCl per mole of water

Answers

Answer : The correct option is, (3) 3.0 moles of HCl per liter of solution

Explanation :

Molarity : It is defined as the number of moles of solute present in one liter of the solution. The S.I unit of molarity is mole per liter.

It is represented as,

$Molarity=\frac{\text{Moles of solute}}{V_(solution)(L)}$

where,

V = volume of solution in liter

As we are given 3.0 M HCl(aq) solution this means that 3.0 moles of HCl present in one liter of solution.

Hence, a 3.0 M HCl(aq) solution contains a total of 3.0 moles of HCl per liter of solution.

Molarity = number of moles / volume in liters solution

Is there a relationship between an elements atomic number and its first ionization energy (IE)?

Answers

yes, well kind of, as you travel across the a period the first ionization energy increases). as you travel down a column the ionization energy decreases.
