The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Calcium Chloride, or 110.984 grams.
Answer:
The balance between intermolecular forces and kinetic energy
Explanation:
If the kinetic energies of the particles are not strong enough to overcome the intermolecular forces, the particles will be locked in place in a crystal lattice. The substance will be a solid.
If the kinetic energies of the particles are slightly stronger than the intermolecular forces, the particles will be able to slide past each other. The substance will be a liquid.
If the kinetic energies of the particles are much stronger than the intermolecular forces, the particles will be escape completely from the attractions of their neighbours. The substance will be a gas.
Answer:
Explanation:
Common ionic charge exhibited by Barium is +2.
Compound formed by Barium and polyatomic ion (X) is Ba(X).
Therefore, ionic charge on polyatomic (X) should be -2 in order to Ba(X) to be neutral.
Common ionic charge exhibited by sodium is +1.
If sodium forms salts with (X), Then, two atoms of sodium will be needed in order to make it neutral. in compounds or salts, no. of atoms are represented as subscripts. Therefore, formula of salts betweem sodium and polyatomic ion should be
