Want this question answered?
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
The type of reaction represented by Zn plus 2NaCl yields 2Na plus ZnCl2 is an impossible one. It would be the other way around. 2Na + ZnCl2 --------> 2NaCl + Zn
Is an excellent example of a series of random letters and numbers that somehow manage to fail utterly at being a question.
Anger is a physical reaction. and it is not chemical. i like physical reactions and chemical reactions.
Metabolic Reaction
Single Displacement
2HCl + Mg = MgCl2 + H2 It is a displacement reaction.
2NaCl + H2SO4 = Na2SO4 + 2HCl
It is a double replacement reaction. MgCl2 + H2SO4 ---> MgSO4 + 2HCl
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
MgO + 2HCl -> MgCl2 + H2O
An acid base reaction producing salt and water. Mg(OH)2 + 2HCl >> MgCl2 + 2H2O
hydrolysis reactions
Mg + 2HCl => H2 + MgCl2 The type of chemical reaction is a Single Replacement.
H2O(aq)+CO2(g)
The type of reaction represented by Zn plus 2NaCl yields 2Na plus ZnCl2 is an impossible one. It would be the other way around. 2Na + ZnCl2 --------> 2NaCl + Zn
double-replacement
