Before the person walks through burning coal, the person will make sure their feet are very wet. When they start walking on the coal, the moisture will evaporate and form a protective gas layer underneath the person's feet.
You can see examples of this if you happen to drip some water on a hot stove or any hot surface. The water will easily glide around on top of a newly formed layer of air underneath it, like air hockey pucks on an air hockey table.
Answer:
Carbon and Oxygen, Argon and Helium.
Explanation:
noble gases have full outer shells of electrons, and so cannot share other atoms' electrons to form bonds. sodium and chlorine form an ionic bond.
Additional oxygen
Explanation : H2O is two hydrogens and one oxygen not 2 hydrogens two oxygens
Answer:
120.575 kJ is the activation energy for the souring process.
Explanation:
The formula for an activation energy is given as:
where,
= rate constant at =
= rate constant at =
= activation energy for the reaction = ?
R = gas constant = 8.314 J/mole.K
= initial temperature =
= final temperature =
Now put all the given values in this formula, we get:l
120.575 kJ is the activation energy for the souring process.
