Goryan [66]3 years ago
5 0

Answer:

No, ΔE does not always equal zero because it refers to the systems internal energy, which is affected by heat and work

Explanation:

According to the first law of thermodynamics, energy is neither created nor destroyed. This implies that the total energy of a system is always a constant.

So, according to the first law of thermodynamics we have that ΔE = q + w. This means that the value of  ΔE depends on q (heat) and  w(work). Hence ΔE is not always zero since it depends on the respective values of q and w.

If the concentration of enzyme increases, then reaction should speed up (answer C).
enzyme speeds up a chemical reaction by lowering activation energy to provide an alternative pathway of reaction mechanism. assuming that enzyme which usually is the limiting factor, the increase of enzyme concentration should lead to more product formation i.e. maltose from the breakdown of starch.
the enzyme discussed here should be amylase.

higher temperature beyond optimum value enzyme found in our human body will usually least to denaturation of active site of enzyme. hence lead to loss of enzyme activity permanently.

When you apply heat energy to a substance, where does the energy go? Think about the law of conservation of energy.
Softa [21]

Answer:

the heat energy is transformed to any kind of energy depending on what it's meant to be transformed to.

remember it cannot be destroyed so it's definitely transformed to some kinda energy

Margaret [11]

Answer:

Explanation:

We know that the composition of Steel includes Carbon and Iron. So, if 2g of steel wool was added to the iron acetate, then the iron acetate is now being reduced. What will happen is that the solution will be triggered as it becomes denser and get highly concentrated. Hence, an increase in concentration leads to a decrease in reaction rates. Thus, a slow reaction will take place, and the reaction rate will decrease.
