On his first day of school, Kareem found the high temperature in degrees Fahrenheit to be 76.1°. He plans to use the function C
2 answers:
Answer:
a. the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius
Explanation:
The function is
C(F) =
Where C is the temperature in ºC, and F is the temperature in ºF. So, when we replace F for the temperature, we can calculate this temperature in degrees Celsius; and when we replace C, we calculate the temperature in degrees Fahrenheit.
In the expression C(76.1), F was replaced by 76.1, so we will calculate the temperature of 76.1 degrees Fahrenheit converted to degrees Celsius.

<u>Answer:</u> The for the reaction is 72 kJ.
<u>Explanation:</u>
Hess’s law of constant heat summation states that the amount of heat absorbed or evolved in a given chemical equation remains the same whether the process occurs in one step or several steps.
According to this law, the chemical equation is treated as ordinary algebraic expressions and can be added or subtracted to yield the required equation. This means that the enthalpy change of the overall reaction is equal to the sum of the enthalpy changes of the intermediate reactions.
The given chemical reaction follows:
The intermediate balanced chemical reaction are:
(1)
(2)
( × 2)
(3)
( × 2)
The expression for enthalpy of the reaction follows:
Putting values in above equation, we get:
Hence, the for the reaction is 72 kJ.
