Answer:
is the energy possessed by an object due to either its motion or its stored energy of position. The total amount of mechanical energy is merely the sum of these two forms of energy. And finally, an object with mechanical energy is able to do work on another object.
Explanation:
B, good luck, hope this helps :)
The balloon started to inflate which suggests that the chemical created a reaction and since the chemical couldn't go into the air or out of the flask it created the gas inside which inflated the balloon. Also you can see little bubbles forming and going to the surface which suggests a gas was produced, I hope this made sense lol XD
The internal energy of the gas is 49,200 J
Explanation:
The internal energy of a diatomic gas, such as 
, is given by
where
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas
For the gas in this problem, we have:
n = 4.50 (number of moles)
R = 8.31 J/(mol·K) (gas constant)
(absolute temperature)
Substituting, we find:
