Answer:
Chemical equation:
3S(s) + 2Fe(s) → Fe₂S₃(s)
Explanation:
Iron metal react with solid sulfur and produced slid iron(III) sulfide.
The chemical reaction is given below:
Chemical reaction:
S + Fe → Fe₂S₃
Balanced chemical equation:
3S + 2Fe → Fe₂S₃
Balanced chemical equation with physical state:
3S(s) + 2Fe(s) → Fe₂S₃(s)
Ionic equation can not be written because all reactant and products are in solid form.
Answer:
(e) CO2 is formed twice as fast as ethane is consumed.
Explanation:
Since we have the equation of the reaction as;
2C2H6(g) + 7O2(g) 4CO2(g) + 6H2O(l)
The rate of consumption of ethene = -1/2 d[C2H6]/dt
Rate of production of CO2= 1/4 d[CO2]/dt
Hence, CO2 is formed twice as fast as ethane is consumed.
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible to set up the initial version of the half-reaction as follows:
Now, we assign the oxidation numbers to both nitrogen atoms:
It means three electrons are carried, two water molecules are needed on the left side in order to balance the oxygen atoms and consequently four hydronium ions to balance hydrogen atoms in acidic media:
