Answer:
MgI₂, MgO, PbI₄, PbO₂
Explanation:
For an ionic compound to be formed, it must be neutral, that is the total positive charge must be equal to the total negative charge.
Mg²⁺ and I⁻: The neutral ionic compound requires 1 Mg²⁺ and 2 I⁻ and the resulting empirical formula is MgI₂.
Mg²⁺ and O²⁻: The neutral ionic compound requires 1 Mg²⁺ and 1 O²⁻ and the resulting empirical formula is MgO.
Pb⁴⁺ and I⁻: The neutral ionic compound requires 1 Pb⁴⁺ and 4 I⁻ and the resulting empirical formula is PbI₄.
Pb⁴⁺ and O²⁻: The neutral ionic compound requires 1 Pb⁴⁺ and 2 O²⁻ and the resulting empirical formula is PbO₂.
Answer:
a. the negative ends of water molecules surround the positive ions.
Explanation:
Ionization reaction is defined as the reaction in which an ionic compound dissociates into its ions when dissolved in aqueous solution.
Thus,
When the ionic compound dissociates, the cation which is positively charged gets attracted to the oxygen (Negative ends) which is present in the water. The anion which is negatively charged gets attracted to the hydrogen (Positive ends) of the water.
Hence, the correct option is:- a. the negative ends of water molecules surround the positive ions.
Answer:
CaS + 2H2O is the balanced equation
Answer:
Then pressure will double
Explanation:
PV = nRT
P = nRT / V
If all other variables are kept constant, P will be proportional to n i.e
P1 / n1 = P2 / n2
n = 1
P1 = P
n2 = 2
P2 =?
P1 / n1 = P2 / n2
P /1 = P2/2
Cross multiply
P2 = 2P
Therefore, if an additional 1mole of the gas is added, the pressure will double
