Chem help please?
a) Zn
b)Mg
Write and equation for the following:
a) Sodium and water react to form sodium hydroxide and hydrogen gas
Answer:
For Zinc(Zn) its a Single Replacement Reaction when you try to react it with HCl. The type of reaction may depend on where you react a certain element or compounds.
for the next question;
2Na + 2H2O --------- 2NaOH + H2
Zn and Mg are metals, not reactions. Melted and mixed, they form an alloy.
2Na + 2H2O -> 2NaOH + H2
Errr...
Zn and Mg are NOT reactions (breathing deeply into paper bag...)
2Na + 2H2O -> 2NaOH + H2
Zn and Mg are natural elements
2Na + 2H20 ----> 2NaOH + H2
Zn and Mg react with acids in this way :
Zn (s) + 2 HCl (aq) >> ZnCl2 (aq) + H2(g)
Mg (s) + 2 HCl (aq) >> MgCl2 ( aq) + H2 (g)
2Na(s) +2 H2O>>2 NaOH (aq) + H2 (g)
