Which Ions oxidize aluminum?<br><br> Li^+, Ca^2+, Ag+, Sn^2+
pishuonlain [190]

Aluminum can be oxidized by Li^{+} and Ca^{2+}

<h3>What is oxidizing?</h3>

Some of the metal corrodes (or oxidizes) and forms the corresponding metal oxide on the surface as a result of a chemical reaction between the metal surface and the oxygen in the air. The corrosion products that occur in some metals, like steel, are highly apparent and loose.

According to reactivity series (The array of metals in the descending order of their reactivities is referred to as the metals' reactivity series. It is sometimes referred to as the metals in the activity series.)

Lithium and calcium ions are more reactive than aluminum ion and they are less electronegative.

Since silver and tin are more electronegative than aluminum so, they cannot oxidize aluminum.

∴ Li^{+} and Ca^{+2} ions can oxidize aluminum.

What is 13.48cm+7.6cm rounded to the correct number of significant figures?
alina1380 [7]
The lowest amount of significant figures has to be what the answer is...

7.6cm is 2 sig figs where 13.48 is 4, so the answer can only really be as precise as the smallest one (7.6)

7.6 + 13.48 = 21.08cm

Put it into 2 sig figs makes it
=21 cm (2s.f) <— don’t forget to write 2 sig figs next to it because otherwise it is a false answer
