The element with the configuration 1s², 2s², 2p⁶, 3s¹ has the ionization energy of 496 kJ/mol. This is because this element has only one electron in its third shell, meaning it will release its electron quickly to attain stable configuration, causing its first ionization energy to be low.
Answer: Rubber source, temperature, thinkness, thread design, driving pattenrs, weather, etc.
Explanation: There are many variables. Here are a few I would include in a tire lifetime study:
1. Type of rubber, including source
2. Thickness of tire
3. Design of tire thread
4. Life as a function of average speed and road surface
5. Expected outside temperature and wet conditions
6. Driving conditions of speed and both acceleration and deceleration parameters (e.g., tire life when slamming on the brakes or accelerating quickly)
