The distinctive odor of vinegar is due to acetic acid, HC₂H₃O₂, which reacts with sodium hydroxide. If a 3.45 mL sample of vinegar needs 42.5 mL of 0.115 M NaOH to be neutralized, how many grams of acetic acid are in a 1.00 L bottle of this vinegar?​

Answers

Answer:

Explanation:

CH₃COOH + NaOH = CH₃COONa + H₂O .

42.5 mL of .115 M of NaOH will contain .0425 x .115 moles of NaOH

= 48.875 x 10⁻⁴ moles NaOH

It will react with same number of moles of acetic acid

So number of moles of acetic acid in 3.45 mL = 48.875 x 10⁻⁴

number of moles of acetic acid in 1000 mL = 48.875 x 10⁻⁴ x 10³ / 3.45 moles

= 1.4167 moles

= 1.4167 x 60 gram

= 85 grams .

So 85 grams of acetic acid will be contained in one litre of acetic acid.

The relative formula mass (M) of a Group 2 metal carbonate is 197
Relative atomic masses (Ar): C = 12
O = 16
Calculate the relative atomic mass (Ar) of the Group 2 metal in the metal carbonate
Name the Group 2 metal.​

Answers

The relative atomic mass (Ar) : 137 and the element : Ba

Further explanation

The naming of chemical compounds is giving a special name to a compound that aims to facilitate the classification of compounds and facilitate the identification of a compound. The rules for naming chemical compounds have been determined by the IUPAC (International Union of Pure and Applied Chemistry)

This nomenclature includes the naming of ion compounds, covalent compounds, and polyatomic

The molar mass of a compound is given by the sum of the relative atomic mass of Ar  

M AxBy = (x.Ar A + y. Ar B)  

Group 2 metals have a +2 charge : M²⁺

So the compound of metal carbonate : MCO₃

Ar C = 12, O = 16

M MCO₃ = (1.Ar M + 1. Ar C+ 3. Ar O)  

[tex]\tt 197=1. Ar~M+1.12+3.16\\\\197=Ar~M+12+48\\\\Ar~M=137[/tex]

The element with relative atomic masses 137 is Ba

So the compound : BaCO₃

pure sodium and chlorine are extremely dangerous, but when combined the result in substance that we use every day. How do you think the properties of sodium and chlorine change when they are combined to make sodium chloride?

Answers

Answer:

Explanation:

chlorine has 7 valence electrons while sodium has 1. on their own, they are very reactive elements. a full valence electron shell has 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive. when sodium and chlorine are combined to form sodium chloride (table salt), it is no longer dangerous. the number of valence electrons changes its reactivity and how it combines.

The properties of sodium and chlorine change when they are combined to make sodium chloride should be explained below.

Information regarding chlorine:

chlorine comprises of 7 valence electrons while on other hand, sodium has 1.  A full valence electron shell contains the 8 electrons, so when elements combine and have 8 electrons in their outer shell, they are not reactive.

The number of electrons in the first three energy levels for four neutral elements is shown in the table. The element with the highest ionization energy is-

Answers

Answer:

The correct option is;

Element 2

Explanation:

The ionization energy is the energy required to eject an electron from a gaseous ion or atom

The ionization energy increases across the period and increases up the group

The elements with the highest ionization energy are those that have the complete octet structure in their outermost shell, which are the noble gases

Therefore, given that element 2, which has the complete octet structure in the outermost shell, then it is an element of the noble gases which have the highest ionization energy in a period, and therefore has the highest ionization energy.

On the periodic table, the element with 10 electrons is Neon, with ionization energy of 2080.68 kJ/mol which is the second highest after helium, that has only 2 electrons.
