Janice’s yard was probably not exposed to as much sun and heat as the yard across the street
Answer:

Explanation:
Hello there!
In this case, since redox reactions are characterized by the presence of a reduction reaction, whereby the oxidation of the element decreases, and an oxidation reaction whereby the oxidation of the element increases.
In such a way, for the given chemical equation, we can see Fe is increasing its oxidation state from 2+ to 3+, which means it is oxidized. On the flip side, Mn is being reduced from 7+ (MnO₄⁻) to 2+ and this, the reduction half-reaction is:

Whereas five electrons are carried.

Answer:
At-207 (meaning At with the number on the top left being 207 and the number at the bottom left being 85.
Explanation:
The sum of the mass numbers has to equal on both sides, so we need 211 = 4+a
a=207
The sum of the atomic numbers as to equal on both sides, so 87=2+b
b=85
The element is determined by the mass number.
