1. Which of the following rules determines the charge on a monatomic Ion formed from a nonmetal?C. 8 - group number
2. Which of the following statements is true?
A. Metals lose electrons to become cations.
The velocity of a 485 kg elevator that has 5900 J of energy is 108.6 m/s
<h3>What is the velocity of the elevator?</h3>
A moving elevator possesses kinetic energy due to its motion.
The velocity of the elevator is calculated from the formula of kinetic energy.
The kinetic energy formula is : Kinetic energy = ¹/₂mv₂
The velocity, v = √2KE/m
v = √(2 * 5900/485)
v = 108.6 m/s
In conclusion, the velocity of the elevator is calculated from the kinetic energy and mass of the elevator.

H₂O₂ + 2FeSO₄ + H₂SO₄ → Fe₂(SO₄)₃ + 2H₂O
H₂O₂ + 2H⁺ + 2e⁻ → 2H₂O k=1
Fe²⁺ → Fe³⁺ + e⁻ k=2
H₂O₂ + 2H⁺ + 2Fe²⁺ → 2H₂O + 2Fe³⁺
