What??? what language is this?
C. Metals higher in the series will replace metal ions in solution that
are lower in the series.
Explanation:
The activity series of metals shows the extent of reactivity of different metals.
On the activity series, the most reactive metals are located higher up on the able whereas the less reactive ones are found at the bottom of the series.
- We can tell if single displacement reactions will occur by simply looking at the reactivity series.
- Metals that are more reactive will displace the ones that are not very reactive that are positioned down the series. Such a reaction will occur.
- Metals lower in the series cannot displace the ones on top because they are less reactive. Such a reaction will not occur.

Answer:
Homogeneous
Explanation:
Homogeneous mixtures are uniform in composition. They have the same proportion of components throughout. Homogeneous mixtures are called solutions. Sugar, paint, alcohol, gold are all examples of homogeneous mixtures because they look the same throughout.
A semiconductor conducts electricity at high temperatures, but not at low temperatures. At high temperatures, metalloids act like metals and conduct electricity.
