The SI unit for distance is metres - m.
The SI unit for speed or velocity is metres per second - m/s.
The SI unit for acceleration is metres per second squared. - m/s^2.
Answer:
I attached a photo of balanced equations but thats as much as I can help.
Explanation:
Answer:
The Lewis structures are shown in the figure
Explanation:
The lewis structure will be drawn using following steps
i) we will calculate the total number of valence electrons in the molecule
ii) will assign one bond (two electrons in between two atoms)
iii) then distribute the rest of the valence electrons as lone pair or shared pair based on completion of octet.
The structure of each molecule is given in the figure.
Valence electrons:

V.E = 5 +(2)6-1=16

V.E =5 +(2)6+7=24
The required empirical formula of the silicon oxide is SiO2.
1. is not a step in most scientific investigations.
