Answer:
0.36 M
Explanation:
Let's consider the following neutralization reaction.
HCl(aq) + NaOH(aq) → NaCl(aq) + H₂O(l)
25 mL of 0.83 M NaOH reacted. The moles of NaOH that reacted are:
0.025 L × 0.83 mol/L =0.021 mol
The molar ratio of NaOH to HCl is 1:1. The moles of HCl that reacted are 0.021 moles.
0.021 moles are contained in 58 mL of HCl. The molar concentration of HCl is:
M = 0.021 mol/0.058 L
M = 0.36 M
Answer:
Soap is a mixture of sodium salts of various naturally occurring fatty acids. ... Soap is produced by a saponification or basic hydrolysis reaction of a fat or oil. Currently, sodium carbonate or sodium hydroxide is used to neutralize the fatty acid and convert it to the salt.

Your answer is:
A volcano spewing out smoke and gases
__________________________
When volcano erupts, various kinds of substances comes out from the interior of earth. A large amount of gases and smoke also come out and enter into atmosphere. These can adversely affect the weather of the area and lead to many health problems.
The magnesium atom looses two electrons which are accepted by each of the fluorine atoms. (Option D).
<h3>What is an ionic bond?</h3>
An ionic bond is formed when two ions are formed by the loss or gain electrons. In this case, magnesium has to loose two electrons while fluorine will gain two electrons.
Thus, the correct steps in the formation of an ionic bond between these atoms are A magnesium atom donates two electrons to the fluorine atoms → Each fluorine atom accepts one of the electrons → The magnesium atom becomes a +2 ion → Each fluorine atom becomes a -1 ion (Option D).
