The reaction which represents an acid-base reaction is: HNO3(aq) + NH3(aq) → NH4*(aq) + NO3(aq).
<h3>What is an acid-base reaction?</h3>
An acid-base reaction is a reaction in which a substance donate protons to another substance which then accepts the proton.
An acid-base reaction usually involves the formation of a salt.
From the given reactions, the acid-base reaction is given below:
- HNO3(aq) + NH3(aq) → NH4*(aq) + NO3(aq)
In the given reaction, HNO3 donates a proton and NH3 accepts the proton.
Therefore, the reaction which represents an acid-base reaction is: HNO3(aq) + NH3(aq) → NH4*(aq) + NO3(aq).

Answer:
A
Explanation:
uranium atoms are fused together
Any of the other alkali metals not mentioned (I.e. rubidium, caesium or francium). They are all group one metals meaning that they contain one valence (outer shell) electron so they will have similar properties. Francium is the most reactive alkali metal while lithium is the least reactive (if you’d like me to explain that let me know :) )
Answer:The correct answer is ;
The oxidation state of nitrogen in NO changes from +2 to 0, and the oxidation state of carbon in CO changes from +2 to +4 as the reaction proceeds.
Explanation:

In an oxidation recation addition of oxygen atom takes place or loss of electrons takes place.
In an reduction reaction removal of oxygen atom takes place or gain of electrons takes place.
In the given reaction , the nitrogen atom is present in +2 oxidation state in NO molecule and present in 0 oxidation state in
molecule. Hence, nitrogen is getting reduced that is reduction reaction. NO is oxidizing agent
In the given reaction , the carbon atom is present in +2 oxidation state in CO molecule and present in +4 oxidation state in
molecule. Hence ,carbon is getting oxidized that is oxidation reaction. CO is a reducing agent.
<u>Answer:</u> The molality of magnesium chloride is 1.58 m
<u>Explanation:</u>
To calculate the molality of solution, we use the equation:

Where,
= Given mass of solute (magnesium chloride) = 75.0
= Molar mass of solute (magnesium chloride) = 95.21 g/mol
= Mass of solvent = 500.0 g
Putting values in above equation, we get:

Hence, the molality of magnesium chloride is 1.58 m
