The salt that is formed during the reaction between potassium hydroxide and hydrochloric acid is
liubo4ka [24]

Answer:

Sodium chloride (NaCl)

Explanation:

According to Arrhenius, an acid is a substance that dissociates to give protons, whereas a base dissociates to give hydroxide ions in an aqueous solution.

Therefore, a chemical reaction in which an Arrhenius acid reacts with an Arrhenius base to give salt and water, is known as a Neutralization reaction.

For example: <u>Neutralization reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH)</u>

A strong acid, hydrochloric acid (HCl) reacts with a strong base, sodium hydroxide (NaOH) to give salt, sodium chloride (NaCl) and water (H₂O).

<em>The chemical equation for this Neutralization reaction:</em>

HCl (acid) + NaOH (Base) → NaCl (Salt) + H₂O (Water)

<u />

<u>Therefore, </u><u>sodium chloride (NaCl) is the salt formed</u><u> during the chemical reaction of hydrochloric acid (HCl) and sodium hydroxide (NaOH).</u>

Match each alkane names and structures.
Scilla [17]

First structure is  CH₃-CH₃. It is an alkane with two carbon atoms hence it is called ethane.

Second structure is  CH₃-CH₂-CH₂-CH₃. It is an alkane with four carbon atoms hence it is called butane.

Third structure is CH₄. It is an alkane with one carbon atom hence it is called methane.

Fourth structure is CH₃-CH₂-CH₃. It is an alkane with three carbon atoms hence it is called propane.

Sesh wants to create a device to transmit an electrical current. He has the following materials: pure water (H2O), brass (Cu3Zn2
Sunny_sXe [5.5K]

Use the brass foil to carry the current, because metals conduct electricity well in the solid state.


Dissolve the calcium chloride in water, because ionic compounds conduct electricity well when dissolved.


Pure water, sugar, or methane are not useful because they are covalent compounds and do not conduct an electric current.
