Answer: The final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .
Explanation:
It is known that the heat capacity of ethylene is 2.145 J/g K. Hence, for 10 moles of ethylene its mass will be as follows.
No. of moles =
10 mol =
mass = 280.5 g
Now, we know that relation between heat energy, mass and specific heat is as follows.
q =
1329.63 = T - 473
T = 1802.63 K
or, =
=
Thus, we can conclude that the final temperature when heat in the amount of 800 kJ is added to 10 moles of ethylene initially at is .
Answer :
(1) The limiting reactant is the reactant that is completely consumed in a chemical reaction. → True
(2) The reactant in excess is any reactant that occurs in a quantity greater than that is required to completely react with the limiting reactant. → True
(3) The amount of product can be calculated based on the amount of limiting reactant. → True
Explanation :
Excess reagent : It is defined as the reactants not completely used up in the reaction. The given moles are more than the required moles.
Limiting reagent : It is defined as the reactants completely used up in the reaction. The given moles are less than the required moles.
Theoretical yield : It is calculated from the amount of the limiting reagent present in the reaction.
Actual yield : It is experimentally determined.
All the given statements are true.
These are the answers. Hope this helps!!!
Answer:
-18.4°F < T(°F) < 96.8°F
Explanation:
The formula to convert Celsius to Fahrenheit is:
Replacing both temperatures in the range (-28°C and 36°C) we get:
So, the range in Fahrenheit is:
-18.4°F < T(°F) < 96.8°F
