Answer:
Magnesium is being oxidized.
Titanium is being reduced.
Explanation:
Hello,
The undergoing chemical reaction is:
Next, oxidation states are assigned:
Half reactions are as follows:
Finally, as the magnesium increases its oxidation state, it is being oxidized and as the titanium decreases its oxidation state it is being reduced.

Answer:
Moles of = 6 moles
Explanation:
The reaction of and
to make
is:
⇒
The above reaction shows that 2 moles of Sc can react with 3 moles of to form
Mole Ratio= 2:3
For 10 moles of Sc we need:
Moles of =
Moles of =
Moles of =15 moles
So 15 moles of are required to react with 10 moles of
but we have 9 moles of
, it means
is limiting reactant.
Moles of ScCl_3= 6 moles
Answer: The correct option is A.
Explanation: The given molecules are the molecules of same element.
These molecules are considered as diatomic species.
Polar molecules are the molecules in which some polarity is present in the bond. These molecules are formed when there is some difference in the electronegativities of the elements. Example: HCl
Non-polar molecules are the molecules where no polarity is present in the bond. These molecules are formed when there is no difference in the electronegativities of the elements. Example:
The given molecules are non-polar in nature.
Hence, these molecules must be non-polar. So, the correct option is A.
