Because it contains hydrogen which isn't formed by a special process like oxygen
Answer:
162.7miles/hr
Explanation:
Given parameters:
Distance covered by the train = 813.5miles
Time taken = 5hours
Unknown:
Speed of the train = ?
Solution:
Speed is a physical quantity.
It is mathematically expressed as;
Speed = 
So, input parameters and solve;
Speed = 
= 162.7miles/hr
Answer:
The temperature of the gas.
Explanation:
According to the kinetic molecular theory, the molecules of a substance are in constant random motion.
If an ideal gas is contained is a sealed rigid container, the average velocity of the gas molecules is dependent of the temperature of the gas.
Recall that temperature is defined as the average kinetic energy of the molecules of a body.
The answer is atoms good luck
