Answer:
For Example, When n-Hexane Is Passed Over Chromium Oxide (Cr2O3) Supported Over Alumina (Al2O3) at 600 degree Celsius, Benzene Is Produced
Answer:
protons, neutrons and the electrons. ... a nucleus made up of protons and neutrons. It houses almost all of its mass and has a positive charge.
Explanation:
un núcleo formado por protones y neutrones. Alberga la casi totalidad de su masa y tiene carga positiva.
An oxygen atom is always made up of 8 protons.
The mass number of an atom is made up of both protons and neutrons.
So to find out the number of neutrons, you subtract the number of protons from the mass number.
Number of neutrons = Mass number - number of protons
So for oxygen with a mass number of 18:
There are: 18 - 8 = 10 neutrons
------------------------------------------------
Answer:
There are 10 neutrons in an atom of oxygen with a mass number of 18.

According to Le Chatelier’s principle, if pressure is increased, then the equilibrium shifts to the side with the fewer number of moles of gas.
Explanation:
- NaCl + AgNO3<------>NaNO3 + AgCl.
- In any reaction a temperature increase uplifts the reaction that absorbs heat which is known as the endothermic reaction.
- The product which absorbs heat, shifts the reaction to the left hand side.
- This shows that the reverse reaction or backward reaction is endothermic.
- if the temperature is increased for an endothermic reaction, essentially a reactant is being added, so the equilibrium shifts toward products.
- Le Chatelier’s principle states that it can be used to predict the behavior of a system due to changes in pressure, temperature, or concentration.
- If the concentration of reactants is increased the reaction is shifted to the right, while increasing the concentration of products will shift the reaction to the left side.
