Why doesnt the number of neutrons identify an element
Goryan [66]

You look at the atomic mass.. The number of neutrons is different for different individual atoms of the same element, each atom is also known an isotope. Looking at a periodic table, the atomic mass listed is the average atomic mass for all isotopes of that element found in nature.

Give the name and formula for the acid derived from each of the following anions:<br> (c) bromite
Travka [436]

The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.

<h3>What is Acids ? </h3>

Acids is defined as substances that is able to donate a proton or hydrogen ion to other substance. Acids acts as proton donor.

<h3>What is Oxoacids ? </h3>

An oxoacids is an acids that contains oxygen. It is also called oxyacids or ternary acids. Oxoacids are the acids of oxoanions.

If anion name contains the suffix ‘ate’ then replace ‘ate’ with ‘ic’.

If anion name contains the suffix ‘ite’ then replace ‘ite’ with ‘ous’.

Given anion is bromite. Formula of bromite is BrO₂⁻. It is an oxoanion.

Now write the name of acid. Here anion name contains the suffix ite so replace the ‘ite’ of bromite with ‘ous’.

The name of the acid is Bromous acid.   

Formula of the acid is HBrO₂.

Thus from the above conclusion we can say that The name of the acid is Bromous acid and the Formula of the acid is HBrO₂.

12.0 of .500 M NaOH neutralized 6.0 ml of HCl solution. What was the molarity of the HCl
frozen [14]

The molarity of the HCl is 1 M when 12.0 of .500 M NaOH neutralized 6.0 ml of HCl solution.

Explanation:

Data given:

molarity of the base NaOH, Mbase =0. 5 M

volume of the base NaOH, Vbase = 12 ml

volume of the acid, Vacid = 6 ml

molarity of the acid, Macid = ?

The titration formula for acid and base is given as:

Mbase Vbase = Macid Vacid

Macid =\frac{0. 5 X 12}{6}

Macid = 1 M

we can see that 1 M solution of HCl was used to neutralize the basic solution of NaOH. The volume of NaOH is 12 ml and volume of HCl used is 6ml.
