Oxidation state or oxidation number : It represent the number of electrons lost or gained by the atoms of an element in a compound.
Oxidation numbers are generally written with sign (+ and -) first and then the magnitude.
When the atoms are present in their elemental state then the oxidation number will be zero.
As per question, 'Mn' atom is a free element that means it is present in their elemental state then the oxidation state will be zero.
Hence, the correct option is, (1) 0
Volume of Al:
D = m / V
2.70 = 96.4 / V
V = 96.4 / 2.70 => 35.70 mL
Mass of iron:
D = m / V
7.87 = m / 35.70
m = 7.87 x 35.70 => 280.959 g
hope this helps!
D leafs because it contains chlorophyll
