The complex CoCl2(en)2 is named as DICHLOROBIS (ETHYLENE DIAMINE) COBALT(II) CHLORIDE.
Here the oxidation number of Cobalt metal is +3. It is a complex compound with no charge on ethylene diamine as it is neutral. The charge on the whole compound is +1.
Answer:
is there an option for silver? if so, silver is the answer.
I think it might be a gas was formed.
Hope I'm right and it helps you out!!
The balanced molecular equation for the reaction between solid sodium bicarbonate and hydrochloric acid to produce carbon dioxide gas, water and aqueous solution of sodium chloride is
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The balanced equation can be written as follow:
Sodium bicarbonate => NaHCO₃
Hydrochloric acid => HCl
Carbon dioxide => CO₂
Water => H₂O
Sodium chloride => NaCl
Sodium bicarbonate + Hydrochloric acid —> Carbon dioxide + Water + Sodium chloride
<h3>NaHCO₃(s) + HCl(aq) —> CO₂(g) + H₂O(l) + NaCl(aq) </h3>
The equation above is balanced since the number of the different atoms of the elements present on both sides are equal.
