Explanation:
Galvanizing protects from rust in a number of ways: It forms a barrier that prevents corrosive substances from reaching the underlying steel or iron. The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
Answer:
B. An ionized atom has a number of protons that is unequal to the number of electrons.
Explanation:
For a neutral atom , the number of proton and electron is equal. An ionized atom has either loss or gain electron, thereby making the number of proton and electron unequal. The answer B is true because an ionized atom has either loss or gain electron to make the number of electron and proton unequal.
Option A is incorrect because a cations holds a positive charge when it loss one or more electron not when it gains one or more electron(s). Anions possess negative charge for gaining electron(s).
Option C is not true because ions can also carry negative charges and they are called anions.
Option D is false because losing one or more electron will turn an atom to a cations.
The relation between rate constants at different temperatures, temperature and activation energy is known as Arrhenius equation
<u>Arrhenius equation</u>
For two temperatures
Where
Ea = ? = activation energy
k1 = 3.36 × 10⁴
T1=344 k
k2=7.69
T2=219K
R= gas constant = 8.314 J /molK
Putting values
Ea = (-69.69)/(-0.00166) = 41981.93 J/mol
Or
Activation energy is 42.0 kJ /mol
