The group number tells us about the size weight and molecule elements involved. Also tells us about what types it can form and combine with as well as its reactions also
Answer:
3.00
Explanation:
Since assuming oxygen as molecule so there are 6 atoms hence 3 molecules of oxygen hence 3 moles
Answer:
<em>Objects with tightly packed molecules are more dense than those where the molecules are spread out</em>
Explanation:
Answer: 1) 2.6 billion years
2) 5.2 billion years
3) 3.9 billion years
Explanation:
Answer:
II) This is because Fe₂O₃ is reduced to Fe and CO is oxidized to CO₂
Explanation:
The equation II which is Fe₂O₃ + 3CO → 2Fe + 3CO₂ is the only exclusive oxidation-reduction reaction since, Fe₂O₃ is reduced to Fe by the removal of oxygen and CO is oxidized to CO₂ by the addition of oxygen.
Equation I is a hydrolysis reaction while equation III is an acid-base reaction. There is change of oxidation number in equations I and III, but they are not exclusively oxidation-reduction reactions.
