Answer:
            <span>A reaction progress curve has three peaks and two valleys between the peaks. This curve describes a reaction mechanism that involves <u>three elementary reactions</u>.

Explanation:
                   I have drawn the progress curve with three peaks and two valleys. In fact the peaks shows higher energy and valleys show lower energies. So, Let suppose we react A and B. This reaction between A and B results in the formation of C. In this reaction the energies of A and B are less, and during the progress of reaction they cross a transition state of higher energy and forms product C with lower energy which is present at lower valley. This was first reaction. Other two reactions will be followed by conversion of C to D and conversion of D into E.</span>

if the balance indicated that the evaporating dish has a mass of 44.8 g and you want to have exactly 5.0 g of copper. what shoul
AleksandrR [38]

49.8 g should be the balance read.

Explanation:

Adding the mass of the evaporation dish 44.8 g with the mass of the copper 5 g you obtain 49.8 g.

On the balance you put first the evaporation dish (or a watch glass) over which you add copper until you reach 49.8 g.
