Explanation:
when Magnesium is reacted with Aluminum oxide, Aluminum being a less reactive metal than magnesium, is replaced by magnesium
Al2O3 + 3Mg - 3MgO + 2Al
hence reaction takes place
To get the concentration of the second solution let us use the following formulae
C1V1=C2V2 where C1 is concentration of first solution and V1 is the volume of solution first solution. on the other hand C2 is the concentration of second solution and V2 is the volume of second solution.
therefore
0.8×2=(2+10)×C2
1.6 =12×C2
1.6/12=C2
C2 = 0.1333mg/mL
Im pretty sure the answer would be 2. Bc that’s how many is shared between O2
Answer:
It maintains the electrically neutrality, also it allows the free flow of ions from one cell to another.
Answer:
It's the third option
Explanation:
Because the particles of the solid are very closed together and packed they can barely move, causing the item to have a fixed shape and volume.
