Each oxygen will have the oxidation number (2-), and we know the total charge is 1-. We have four oxygen atoms per molecule, so we can set up the equation:
(charge on Mn) + 4(charge on O) = -1
(charge on Mn) + 4(-2) = -1
(charge on Mn) - 8 = -1
Charge on Mn = 7
The answer is C. 7
Answer:
47,070J
Explanation:
Because we use the formula
Eh= m×c×∆T
Which is energy required equals mass times specific heat capacity times change in tempreture (final temp - initial temp )
Its a reactant, comes on the left side of the yielding arrow.
The very first step would be to formulate a testable hypothesis.
The electron orbits the nucleus so your answer would be C.
