(1) Copper:
Copper has the atomic number : 29
Cu2+ means that it lost 2 electrons, therefore, the total number of electrons is 29-2 = 27 electrons.
The electronic configuration is:
1s2 2s2 2p6 3s2 3p6 3d9
(2) Silver:
Silver has atomic number : 47
Ag + means that it lost one electron, therefore, the total number of electrons is 47-1 = 46 electrons
The electronic configuration is:
<span>1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10</span>
It rises. it can steam before an after boiling point.

Answer:
It will take 8.09 seconds to cover 235 meters by car with speed of 65 mile/h.
Explanation:
Speed of the car = 65 mile/h = 65 1609.34 m/h = 104,607.1 m/h
1 mile = 1609.34 m
Distance covered by the car in t time = 235 m = mile



t = 0.002246 h
1 hour = 3600 seconds
0.002246 h = 0.002246 h × 3600 seconds = 8.09 seconds
It will take 8.09 seconds to cover 235 meters by car with speed of 65 mile/h.
