<u>Answer:</u> The ionic compound formed is magnesium chloride having formula 
<u>Explanation:</u>
Ionic compound is defined as the compound which is formed by complete transfer of electrons from one atom to another atom.
The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.
Magnesium is the 12th element of the periodic table having electronic configuration of 
This element will loose 2 electrons to form 
ion
Chlorine is the 17th element of the periodic table having electronic configuration of 
This element will gain 1 electron to form 
ion
So, for every 1 atom of magnesium, 2 atoms of chlorine are required. Thus, the chemical formula becomes
Hence, the ionic compound formed is magnesium chloride having formula
, THR CC14 formed in the first step is used as the reactant used in the second step.if 5.00 mol of CH4 reacts, what is the total amount of HCI producded. assume that C12 an HR in the presentin excess
The chemical symbol for manganese is Mn.
Ionic charge = +4
To answer this we look only at the protons and electrons. Because there are 4 more protons than electrons we know that this ion has 4 less electrons than it would need to have to have a neutral charge. Therefore, the ionic charge is +4
Answer:
Exothermic reaction.
Explanation:
From the question given, we obtained the following:
The equation for the reaction:
A —> C
From the diagram given in the question above, the reactant, A has a higher energy than the product, C. This simply indicates exothermic reaction as the enthalphy change, ΔH will be negative for the reaction.
Enthalpy change, ΔH is simply the difference between the heat of product, Hp and the heat of reactant, Hr i.e
ΔH = Hp – Hr
Since the heat of the product is small, the enthalphy change, ΔH will be negative indicating that heat has be released to the surroundings. This is termed exothermic reaction.
