Answer 2

The given expressions appear to represent chemical reactions involving different compounds. Here's a breakdown of each reaction:

1. Al + O2: This represents the reaction between aluminum (Al) and oxygen (O2). The balanced equation for this reaction is:

2 Al + 3 O2 -> 2 Al2O3

In this reaction, aluminum reacts with oxygen to form aluminum oxide (Al2O3).

2. BaCk2 + Na2SO4: It seems there might be a typo in this expression. It's unclear what "Bk" represents. If it's meant to be "Ba," the balanced equation for the reaction between barium (Ba) chloride (BaCl2) and sodium sulfate (Na2SO4) would be:

BaCl2 + Na2SO4 -> 2 NaCl + BaSO4

In this reaction, barium chloride reacts with sodium sulfate to form sodium chloride and barium sulfate.

3. SiO2 + H2O: This represents the reaction between silicon dioxide (SiO2) and water (H2O). The balanced equation for this reaction is:

SiO2 + 2 H2O -> H4SiO4

In this reaction, silicon dioxide reacts with water to form orthosilicic acid (H4SiO4).

Please note that chemical reactions can have various conditions, such as temperature and pressure, which may affect the reaction outcomes.
