Answer:
150km/hr
Explanation:
When it flies 50km, the average speed is 150km/hr.
When it flies 30 km, how many minutes does it take?
Answer:
The transition elements have their valence electrons in two different sets of orbitals that are (n-1)d and ns. Thus, transition elements show variable valencies due to the involvement of penultimate d shell electrons.
Explanation:
The answer is :
2H₂O (l) ------>2H₂ (g) + O₂ (g)
That is ,
Oxidation number of oxygen increases in reaction :
2H₂O (l) ------>2H₂ (g) + O₂ (g)
In H₂O, oxidation number of oxygen is -2 but in O₂ molecule it is 0.
So, oxidation number of oxygen increases in this reaction that is from -2 to 0.
So in the reaction that is 2H₂O (l) ------>2H₂ (g) + O₂ (g) , oxidation number of oxygen increases .
