An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. An example is Iron (III) , Iron (II) , lithium, and hydrogen.

A chemist dissolves 614. mg of pure hydrochloric acid in enough water to make up 400 mL of solution. Calculate the pH of the sol

tatuchka [14]

Answer:

The pH of the solution is 1.38.

Explanation:

Mass of HCl = 614 mg = 0.614 g

Moles of HCl = $\frac{0.614 g}{36.5 g/ mol}=0.01682 mol$

Concentration of HCl :

$Concentration =\frac{Moles}{\text{Volume of solution in L}}$

On adding 0.01682 moles to 400 mL of water that 0.4 L of water.

$[HCl]=\frac{0.01682 mol}{0.4 L}=0.04205 M$

$HCl(s)+H_2O(l)\rightarrow H_3O^+(aq)+Cl^-(aq)$

1 mole of HCl gives 1 mole of hydronium ion and 1 mole of chloride ions in an aqueous solution.

Then 0.04205 mol/L of HCl will give:

$1\times 0.04205 M =0.04205 mol/L$ of hydronium ions.

$[H_3O^+]=0.04205 M$

$pH=-\log [H_3O^+]$

$pH=-\log [0.04205 M]=1.38$

The pH of the solution is 1.38.

when a person uses an iron to remove the wrinkles from a shirt, why does heat travel from the iron to the shirt?

valentina_108 [34]

In physics, there is a rule that the heat always travels from the hotter object to the cooler object. In this case, as the iron is hotter than the shirt, the heat will travel from the iron to the shirt.
