Titanium will react with magnesium oxide but sodium reacts with titanium oxide.
The position of titanium will be
a. above sodium
b. .below magnesium but above iron
c. below sodium but above magnesium
d.. below silver

below sodium but above magnesium

Explanation:

It is necessary to note that only a metal that is above another metal in the activity series can displace it from its compound.

The first statement said that titanium reacts with magnesium oxide. The implication of this is that titanium can displace magnesium from its oxide. This is only possible if titanium is above magnesium in the activity series.

The second statement says that sodium reacts with titanium oxide. This implies that sodium metal can displace titanium from its oxide. For this to occur, then sodium must be above titanium in the activity series of metals. Hence the answer above.

answer; i believe that the correct answer is (a) potassium(k)

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
