Predict the products.

Ba(s) + O2 (g) -> ????

SO2 (g) -> ???
(On the sheet it says the products are elements for this particular equation)

The product for the first one probably is the peroxide, BaO2, if Ba is burned in pure oxygen.

The second one I would write no reaction because no conditions are listed. In general, SO2 is relatively stable. However, if your sheet says elements, the only elements you can get are S and O2. BUT, I don't really believe that.

URGENT!

PLEASE HELP ME!! :)
Thanks!

THANK YOU DR BOB!

To predict the products of a chemical reaction, we need to recognize the type of reaction it is. Let's analyze each of these reactions:

1. Ba(s) + O2(g):
This is a combination or synthesis reaction, where two or more substances combine to form a single product. In this case, the metal barium (Ba) reacts with oxygen gas (O2). To predict the product, we need to check the valence of Ba. Barium typically has a +2 valence. Oxygen, on the other hand, usually has a -2 valence. Since the charges must balance in the resulting compound, the product is likely to be barium oxide (BaO). Therefore, the balanced equation would be:

2 Ba(s) + O2(g) -> 2 BaO(s)

2. SO2(g):
For this reaction, we are given a single substance, sulfur dioxide (SO2). We are also told that the products are elements, which implies that the reaction is a decomposition reaction. In a decomposition reaction, a single compound breaks down into two or more simpler substances. However, it's important to note that SO2 is already a compound and not an element.

If we want to represent a decomposition reaction with SO2, we can consider breaking it down using energy or heat as catalyst:

SO2(g) -> S(s) + O2(g)

In this case, sulfur (S) and oxygen (O2) are the products resulting from the decomposition of sulfur dioxide.

However, since your sheet states that the products are elements, it may be referring to a different reaction or some other specific condition. I would recommend double-checking your information or referring to additional context if available to accurately predict the products.
