Answer:
The answer to your question is: 82.9 %
Explanation:
Data
H2 = 42.6 g
NH3 = 200 g
percent yield = ?
Reaction
3H2 + N2 ⇒ 2NH3
Process
6 g of H --------------- 34 g of N
42.6 g ------------- x
x = 241.4 g of NH3
percent yield = 200 / 241.4 x 100
= 82.9 %

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)
The atomic number is underlined in blue and the atomic mass is underlined in red. The number of protons and electrons is equal to the atomic number. The neutrons is equal to the atomic mass minus atomic number. The group is the vertical column the element is located in (circled in greenish), while the period is the horizontal row (circles in orange).
