Hello,
In this case, we use the equation regarding the first law of thermodynamics which is:
In this case, the want to compute the change in thermal energy of the gas which is related with ΔU. In such a way, since the 10 J are being removed, they are set as negative in the aforesaid equation, moreover, the 40 J of work are positive since it is a work done on the system. Hence:
Best regards.
Answer:
i think the answer would be C
Explanation:
no matter what you do to the jar the mass will stay the same. unless you add more nails
Given: 2.00 m h2so4 / L
0.250 moles
Solve
To get the volume we need to divide 0.250 moles from 2.00 moles / L
Volume = (0.250 moles)
-----------------------
(2.00 moles/L)
= 0.125 L x 100
= 125 ml
So the answer is 125 milliliters of 2.00 m h2so4 are necessary to provide 0.250 mole of it.
Answer:
See detailed explanation.

Hello!
In this case, for the reaction:
It is known that the equilibrium constant tends to be greater than 1; therefore, it is a reaction that tends to go rightwards towards the formation of hydrogen iodide.
a) Here, since the reaction tends to form the product, it is clear that the initial concentration of iodine and hydrogen will decrease as the reaction reaches equilibrium in order to increase the concentration of hydrogen iodide.
b) Yes, it stops at the point in which the following expression:
Equals the equilibrium constant.
