Yes, remember a chemical reaction is whenever one or more substances combine together to form a different substance. So whatever you put together and form something new is called a chemical change/reaction. Examples such as rusting of Iron, expired milk(going sour), Baking cake and many more to think about
Hope it helps
Temperature is related to the kinetic energy the atoms within any given
substance. Within a solid, we can therefore assume that the density will
increase as the solid is cooled to a low temperature, as this will
cause a loss in kinetic energy and the atoms won't be able to move as
freely.
We are going to use this formula:
E° = 0.0592/ n * ㏒K
when E° is the standard state cell potential
and n is number of moles of electrons transferred in the balanced equation
for the reaction of the cell.
Sr(s) + Mg2+ (aq) ↔ Sr2+(aq) + Mg(s)
we can get it by using the given balanced equation, we here have 2 electrons
transferred so, n = 2
and K the equilibrium constant = 3.69 x 10^17
so, by substitution:
∴ E° = 0.0592 / 2 * ㏒ (3.69 x 10^17)
= 0.52 V
Have faith in yourself always. Don't worry about what other people say. Love yourself a lot
CI- the chloride ion is the anion CI its formed when the elements gains electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.
