B. 3+
Explanation:
When Fe²⁺ loses an electron, it becomes an Fe³⁺ ion.
The loss of an electron in an atom makes the atom becomes positively charged. Further losing electrons makes the atom more positive.
For the given ion;
Fe²⁺ if it loses an electron more, it becomes Fe³⁺.
The expression is given as:
Fe²⁺ → Fe³⁺ + e⁻
Answer:
147,558,601 sqkm
Explanation:
The earth is spherical in shape;
area of sphere = 4πr²
if 70.8% is covered by water then 100-70.8 will be land,
= 29.2%
area occupied by land = (29.2/100) * 4πr²
= 0.292*4*3.142*(6371)²
=147,558,601 sqkm
