Answer:
2.7×10⁻³ mole
Explanation:
Applying
Q = it.............. Equation 1
Where Q = amount of charge, i = current, t = time
From the question,
Given: i = 0.860 A, t = 5 minutes = (5×60) seconds = 300 seconds
Subsitute these values into equation 1
Q = (0.860×300)
Q = 258 C
If one mole of electron has a charge of 96500 C
Then, x mole of electron will have a charge of 258 C
1 mole ⇒ 96500 C
X moles ⇒ 258 C
Solve for X
X = (258×1)/96500
X = 2.7×10⁻³ mole
Oxidizing acids, such as nitric acid, can explode when mixed with what type of incompatible chemicals like alcohol, or charcoal.
An oxidizing acid is a Brønsted acid that is a strong oxidizing agent. most Brønsted acids can act as oxidizing agents because the acidic proton can be reduced to hydrogen gas. a few acids include other structures that act as stronger oxidizing agents than hydrogen ions.
Oxidizing acids include concentrated perchloric acid, nitric acid, iodic acid, chromic acid, and the glass cleansing mixture of chromium trioxide and sulfuric acid.

Answer:
Science, Science, Science!
Explanation:
Reeeeeeeeeeeeeee
265
your answer would be 265. Because the charge of +1 means there is one more proton then electron. So, 108 protons plus 157 neutrons gives you your mass number of 265.
