Answer:
336.8 kilo Joules is the change in internal energy of the system.
Explanation:
The equation for first law of thermodynamics follows:
where,
Q = heat added to the system
ΔU = Change in internal energy
W = work done
We have :
Amount of heat given out by the system will be negatuive as heat relased by the system = Q
Q=
Work done on the system will positive as work is done on the system:
w =
336.8 kilo Joules is the change in internal energy of the system.
Answer:
(B)
Explanation:
The colligative properties of any given solution are properties that are dependent on the concentration of the molecules or ions of the solute in the solution, and not on the type or identity of that solute. Examples of colligative properties:
1. Lowering of vapour pressure
2. Elevation of boiling point,
3. Depression of freezing point and
4. Osmotic pressure
(A) is not a colligative property because the scenario talks about the freezing point of a pure solvent and not a solution.
(C) is not a colligative property because the solutions being compared are completely different (the solutes are different).
(B) is a colligative property because it talks about the freezing point of a solution
Answer:
B) Changing the enzyme concentration
The correct answer for the question that is being presented above is this one: "c. clearcutting." Clearcutting<span>, clearfelling, or </span>clearcut<span> logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Clearcutting in itself is not an effective way to manage forests and trees.</span>
Answer:
The correct choice is option C) The reactant that runs out first and limits how much product can be made
Explanation:
The limiting reactant is a reactant in a chemical reaction that gets consumed first and thus limits how much product can be formed.
