Chemical reactions can be detected by: _________
a) color change from reactants to products
b) the production of a precipitate
c) a change in temperature
d) an increase of surface area


Sagot :

(A)  Color changes from reactant to products.

The rate of a chemical reaction is calculated by dividing the rate of change in a reactant or product's concentration by the coefficient from the equation's balanced state.

2N2O5(g)    →  4NO2(G) + O2(g)

A change in color and the appearance of bubbles are two indications of a chemical shift.In a chemical process, the makeup of the components changes; in a physical change, the appearance, smell, or straightforward exhibition of a sample of matter changes without changing its composition.

Despite the fact that we refer to them as physical "reactions," nothing is actually changing. A change in the substance in question's elemental composition is necessary for a reaction to occur. Therefore, from now on, we will simply refer to bodily "reactions" as physical changes.

Physical modifications must only cause a variation in display without altering the composition. Typical modifications include, but are not limited to:

Texture\Color\Temperature\Shape
