there are 6 moles of oxygen in Zn(No3)2
Answer:
0.032 L or 32 mL
Explanation:
Use the dilution equation M1V1 = M2V2
M1 = 9.0 M
V1 = This is what we're looking for.
M2 = 0.145 M
V2 = 2 L
Solve for V1 --> V1 = M2V2/M1
V1 = (0.145 M)(2 L) / (9.0 M) = 0.032 L
Same number of valence electrons
Explanation:
Two elements posses similar chemical properties if they have the same number of valence electrons.
Chemical properties of any substance is determined by the number of valence electrons it possesses in its outer most shell.
Elements use their valence electrons to form chemical bonds with one another.
Elements with the same number of valence electrons will chemically combine the same way.
This is why elements in the same group on the periodic table have the same chemical properties.
