3 molecules because of the coefficient 3 on the very front
Running cars on electricity would conserve gasoline because electric cars do not use the same resources.
To find the density of any sample, you need to know the Mass (grams), and its Volume (measured in mL or cm³). Divide the mass by the volume in order to get a sample's Density.
Density (P)= Mass(m)/Volume(V)
P=m/V
P=245.8grams/94ml
<span>P=2.65grams per ml </span>
Answer:
A)Chlorine and Bromine:
They are both non metal hence they form a covalent bond due to covalent bonding.
B)Potassium and Helium:
Helium ion has a small cationic radius and distorted by the potassium ion due to polarization.
C)Sodium and Lithium:
Both are metals hence they form a metallic bond since they share electrons to the electron cloud.
It is false because electrons have no mass.
