Answer:
Hey , I can't see the picture
Answer:
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.
<em>M H₂O: 1g×2 + 16g = 18g
</em>
6,02×10²³ --------- 18g
3,01×10²³ --------- Xg
X = (18×3,01×10²³)/<span>6,02×10²³
<u>X = 9g

Answer:
Balanced reaction: 
S is oxidized and N is reduced.
is the oxidizing agent and ZnS is the reducing agent.
Explanation:
Reaction: 
Oxidation: 
Balance charge: 
...............(1)
Reduction: 
Balance H and O in acidic medium : 
Balance charge: 
...............(2)
[
Equation-(1)] + [ 
Equation-(2)]:
Oxidation number of S increases from (-2) to (0) for the conversion of ZnS to S. Therefore S is oxidized.
Oxidation number of N decreases from (+5) to (+2) for the conversion of to NO. Therefore N is reduced.
consumes electron from ZnS. Therefore is the oxidizing agent and ZnS is the reducing agent.
