The balance chemical reaction describing the reaction between Mg2+ and Cl- is shown below,
Mg2+ + 2Cl- ----> MgCl2
This is a reaction where there is a transfer of electrons. Since the valence electron of Mg2+ is 2 and that of Cl- is only 1. There is a need for 2 Cl- to react with 1 Mg2+ in order to balance the equation.
Thus, the anwer is MgCl2.
Answer:
group
Explanation:
elements in the same group have the same number of valence electrons
Answer:
C. 2.3 moles of oxygen (O2)
Explanation:
Answer:
a) 0
Explanation:
Each of the small dots surrounding the C1 represents one electron. These are where electrivity comes from. Since there is the same number of electrons in both atoms, the difference is 0 (because 6 electrons-6electrons= 0).
Answer:
A) { + } Ge-Se { -}
B) { + } Ge-Br { - }
C) { - } Br-Se { + }
Explanation:
The (-)ive sign shall be placed for the atom with higher electronegativity, while the other atom will be electropositive.
a) Electronegativity of Ge = 2.01
Electronegativity of Se = 2.55
{ + } Ge-Se { -}
b) Electronegativity of Ge = 2.01
Electronegativity of Br = 2.95
{ + } Ge-Br { - }
c) Electronegativity of Br = 2.95
Electronegativity of Se = 2.55
{ - } Br-Se { + }
