Question

PLEASE HELP THANKS

A student performs an exothermic reaction in a beaker and measures the temperature. If the thermometer initially reads 35 degrees Celsius, what is a possible reading of the thermometer after the reaction? 

      A. 45 degrees Celsius  B. 0 degrees Celsius  C. 35 degrees Celsius  D. 25 degrees Celsius​

Answer 1

i think 35 degrees Celsius

Step-by-step explanation:

cause its the same temperature

Answer 2

The answer is: A. 45 degrees Celsius

Step-by-step explanation:

Answer:

In order to solve this problem, you need to know that an exothermic reaction is a chemical reaction that releases energy through light or heat to the environment, in the other hand, an endothermic reaction is a chemical reaction that absorbs heat from its environment.

In the problem says that an exothermic reaction is performed at a temperature of 35 degrees Celsius.

Now, keeping in mind that a exothermic reaction release heat, we can affirm that the temperature of the sistem will by increased after the reaction occurs.

Finally, the only possible answer is A, because is the only temperature which is superior to the initial temperature (35 degrees Celsius)
