Solution :
Cd(s) ----------------------> 
(aq) + 2
, 
= 0.34 v
(aq) + 2 ------------> Cu (s) , = -0.04 v
----------------------------------------------------------------------------------------------
Cd(s) + (aq) -------------> (aq) + Cu (s) , = 0.30 v
The cell potential is defined as the measure of 
between the 
of an electrochemical cell.
Answer:
1}800m/s
2}80m/s²
Explanation:
1]first convert the kilometers to meters so as to obtain similar units;
16×1000=16000m (1Km=1000m)
then divide the ditance by time:
speed=distance/time
=16000m/2s
=800m/s
2]acceleration=(initial velocity -final velocity)/time taken
=(800m/s-0m/s)/10s
=800m/s/10s
=80m/s²
Answer:
No
Explanation:
If you added the reactants on the reactant side because there is one atom for nitrogen on the product side while there is two atoms on the product side. There are more hydrogen products on the reactant side as well.
