ANSWER
Option A
EXPLANATION
Arrhenius defines an acid as a substance that will produce hydrogen ions as the only positive ion when dissolved in water.
He also defines a base as a substance that contains a hydroxide ion (OH^-).
Hence, the Arrhenius Model of acids and bases applies that is applied to the aqueous solution.
The correct answer is option A
Answer: The temperature at the point of intercept is -273°C.
Explanation: Intercept is a point on a graph which crosses the x and y axes.
Here, The X-axis represents Temperature in °C and Y-axis represents the Volume in mL.
On X-axis, the major division is 100 and minor division is 10. The slope intercepts the X-axis at third minor division from the origin. Hence, the temperature of intercept corresponds to -273°C.
The term conservation of mass means that mass in any system can neither be created nor destroyed but can be transformed from one state to another.
<h3>What is the law of mass of conservation?</h3>
The law of conservation states that the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.
This means that when an element is involved in a chemical reaction, it's mass remains the same at the end of that reaction.

Explanation:
The combustion of ethanol is best represented by the equation below:
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O + heat
Combustion process is very common among hydrocarbons.
Ethanol is an alcohol and in the presence of oxygen it will combust.
In combustion heat energy is always released into the environment.
C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O + heat
We see that ethanol combines with oxygen to give carbon dioxide and water in the reaction above.
The heat produced signifies that the reaction is exothermic in nature.
