<span>A neutralization reaction is a reaction in which an acid and a base react in an aqueous solution to produce a salt and water. An example of a neutralization reaction is the reaction of sodium hydroxide and hydrogen chloride to form sodium chloride and water. Answer is C.</span>
Answer: Sheila's top brick will be cooler than Ralph’s top brick, because Sheila’s started with more total energy, so less energy had to transfer for both her bricks to reach the same total energy.
Explanation:
Yes, it is a correct approach because endothermic reactions absorb heat. In consequence, the amount of heat can be used to classify this reaction.
<h3>Endothermic and exothermic reactions</h3>
An exothermic reaction is a type of chemical reaction that releases heat, thereby increasing the temperature of its surrounding environment.
Conversely, an endothermic reaction can absorb heat, thereby cooling its surrounding environment.
In consequence, the amount of heat measured after the reaction can be indicative of the type of chemical reaction.

Answer: Carbonic acid occurs naturally in the body and performs important regulatory functions.
Explanation: Carbonic acid ( ) is an acid formed from the carbon dioxide present in the body. It is also known as the respiratory acid as it helps in the transport of carbon dioxide in the body.
With the help of enzyme Carbonic Anhydrase, carbon dioxide is converted into carbonic acid. This acid is an unstable intermediate which gets dissociated into bicarbonate ions ( ) and ions. immediatley.
Therefore, Carbonic acid performs important regulatory functions in the body.
The mass of the product in a chemical reaction must be equal the mass of the reactants.
