Answer: two
Explanation:
Oxidation Number of Nitrogen in NO2 (Nitrogen Dioxide) Nitrogen dioxide (NO2) is a molecule which contain two oxygen atom and one nitrogen atom.
Answer:
3.3 * 10^-12
Explanation:
The balanced equation of the reaction is;
2H+(aq) + Cu(s) ---------> H2(g) + Cu2+(aq)
Hence two electrons were transferred so n=2
E°cell = E°cathode - E°anode
E°cell = 0 V - 0.34 V
E°cell = - 0.34 V
Then;
E°cell = 0.0592/n log K
Substituting values;
- 0.34 = 0.0592/2 log K
- 0.34/0.0296 = log K
-11.486 = log K
K = Antilog (-11.486)
K = 3.3 * 10^-12

Answer:
a- Uno de carbono y dos de azufre
Explanation:
El compuesto formado entre el carbono y el azufre es CS2.
El carbono forma dos enlaces dobles con dos átomos de azufre.
Por lo tanto, el compuesto contiene un átomo de carbono y dos átomos de azufre.
