MgCl2 is ionic compound.........Mg +2 and Cl -1
both charges are cross multiplied to each element......formula tells us that to balance the positive and negative charges on both sides they are cross multiplied........MgCl2......meaning there is one atom of Mg and 2 atoms of Cl.......
HOPE IT HELPS !!!
three dots belong in the electron dot diagram of a boron(B) atom.
Potential energy is energy stored in an object due to its position or arrangement. Kinetic energy is energy of an object due to its movement - its motion. All types of energy and be transformed into other types of energy. This is true for potential and Kinetic energy as well.
C. 2-
electrons have a negative charge, thus adding two electrons to an atom will give it a charge of 2 times -1 or -2
The data must be reproducible: it means that the data will be reliable and representative and not that this data would lead to one conclusion and another data would lead to another.
Data being varied, unique or surprising does not have anything to do with acceptability of the conclusion.
