Which compound could serve as a reactant in a neutralization reaction?(1) NaCl (3) CH3OH(2) KOH (4) CH3CHO
2 answers:
Answer: (2)
Explanation: When an acid reacts with the base then it undergoes neutralization to form a salt and water.
An acid is a substance that ionizes in the water to give hydrogen ion and have pH less than 7.
A base is a substance that ionizes in the water to give hydroxide ion and has pH more than 7.
Thus being a base can be a reactant in neutralization reaction.
being a salt can be a product in a neutralization reaction.

Hello. You forgot to replace the map needed to answer that question. The map is attached below:
Answer:
B) west to east
Explanation:
The letter H on the map represents an area with high air pressure, while the letter L represents an area with low air pressure. As in the areas of lower temperature or colder the pressure is greater, the wind leaves these areas and goes towards those of higher temperature, which present less pressure. For this reason, we can say that the wind is moving from west to east.
The greater the pressure difference between the regions, the greater the wind speed, and in these situations, strong winds or winds can occur, which are given different names, depending on the location: hurricane (Caribbean), tornado (USA), typhoon (Asia).
