Answer:
The reaction combines the sodium with the hydrogen and oxygen in water to form sodium hydroxide and hydrogen gas, and you get a lot of energy released as heat as well. This heat actually melts any remaining sodium that has not reacted yet, and ignites the hydrogen gas, so you get the bang and the flash.
Explanation:
i would say Psychoanalysis so you need to call Frasier Crane lol
hope it helps
I would say it’s helps with basic reproduction and let’s animals develop more.
<u>Answer:</u>
(A)
Density = Mass / Volume
So
Mass = Density × Volume
Mole ratio of toluene : Oxygen is 1 : 9
(B)
1 mole of Toluene produces 7 moles of 
gas and 4 moles of 
Vapour
So the mole ratio is 1 : 11
(C)
1mole contains 
molecules
The electron group arrangement of NO²⁻is trigonal planar. The molecular shape is bent, and the bond angle is 120°.
<h3>What is the molecular shape of a compound?</h3>
The molecular geometry of the compound shows the position of nuclei and the electron of the compound. It shows how the joining of electrons and nuclei makes the shape of the compound.
Like here, the shape of nitrite is bent with lone pair which is shown by Lewis's structure The bond angle will be the distance between the nuclei of the neighbor atoms.
Thus, the electron geometry arrangement of nitrite is trigonal planer with a bent shape and the bond angle will be 120°.
