Answer:</h3>
1 x 10^13 stadiums
<h3>
Explanation:</h3>
We are given that;
1 stadium holds = 1 × 10^5 people
Number of iron atoms is 1 × 10^18 atoms
Assuming the stadium would carry an equivalent number of atoms as people.
Then, 1 stadium will carry 1 × 10^5 atoms
Therefore,
To calculate the number of stadiums that can hold 1 × 10^18 atoms we divide the total number of atoms by the number of atoms per stadium.
Number of stadiums = Total number of atoms ÷ Number of atoms per stadium
= 1 × 10^18 atoms ÷ 1 × 10^5 atoms/stadium
= 1 × 10^13 Stadiums
Thus, 1 × 10^18 atoms would occupy 1 × 10^13 stadiums
Answer:Zn(OH)2(s) + 2e– Zn(s) + 2OH–(aq) E°= –1.25 V
Explanation:
The best reducing agent must have the most negative reduction potential. According to iupac convention, the reduction potential is used to depict the standard redox potentials of substances. Reducing agents have very negative reduction potentials while oxidizing agents have more positive reduction potentials.
