Answer:
5 valence electrons
Nitrogen has a total of 5 valence electrons
Explanation:
Answer:
0.0970 M
Explanation:
Remember this equation:
mol/M x V
Convert it so that you can get M.
M=mol/V
Convert the 2.14 grams of H2SO4 into mols
=0.0218
Convert mL to L
225/1000
=0.225
Plug it in.
0.0218/0.225
=0.0970 M
Answer: a) copy tissue
Explanation:
Tissue and cells in general get damaged, or just break down from wear and tear. So the cells divide to make up for this shortcoming, effectively replacing any broken parts with fresh new ones.
The correct method would be multiplying the speed of light by the time it takes to travel from the moon to Earth. This is because:
S=So+V*t
In which:
S= space
So= space at the start (origin)
V=speed or velocity
t=time
By multiplying miles/second by seconds you get miles as a result.
