1s^2 2s^2 2p^6 for the Mg2+ ion.
3 is C i believe, and as for 4 minerals are solid, natural.. that's about all I can say...
Density can be calculated using the following rule:
density=mass/volume
therefore,
volume=mass/density
we have mass=0.451g and density=0.824g/ml
substituting in the above equation, we can calculate the volume as follows:
volume = 0.451/0.824 = 0.547 ml
Answer:
As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.
Explanation:
The equilibrium shifts to the side having the lesser volume or number of moles
Explanation:
Reaction 2N₂
+ 3H₂
⇄ 2NH₃
This reaction, haber process is completely a combination of gaseous molecules.
An increase in pressure will shift the equilibrium position to the right hand side i.e the side with the lesser volume or number of moles.
Number of moles
Reactants Products
5 2
The product side has a lesser number of moles and the equilibrium shifts to the right hand side.
