Give three examples of electron configuration‘s for atoms on the periodic table with the same activity that can be attribute it to there being two electrons in the outer most energy level.
pls idk what this means or how to do it : )
an inert electrode is made up of non reactive metals like platinum
an inert is electrode is required in one of the half cells or both the cells if there is no solid conducting metal in either half reaction. or we can say that if in any half reaction neither product nor reactant is in solid phase.
from the given equations it is clear that
a) in first cell we have cu and ag in solid phase in either side
b) in second reaction the iron is in aqueous phase on both the side of reactant and product
so for reduction of iron or in cathodic half cell we need inert electrode [which does not participate in reaction]
hence answer is
c) in third reaction zn and sn are in solid phase in either side
d) in fourth reaction al and ni are in solid phase in either side
the answer is 8 m/s^2explanation:
acceleration is defined as the rate of change of an object's velocity, per unit time. meaning, the rate at which an object is increasing/decreasing its velocity with the passage of time in a given period.
if an object is moving at constant velocity, its acceleration would be 0, because there is no change in velocity. in our case, the velocity is increasing, and to calculate this, we will use a simple formula,
acceleration = change in velocity / time
and change in velocity is calculated by subtracting the value of initial velocity (u) from final velocity (v).our known values are:
u = 7m/s
v = 15m/s
a = ?putting the values in the equation for acceleration:
a = u - v / t
a = 15 - 7 / 1
a = 8 m/s^2
hope this !
