Chemical Reactions and Products

The given chemical reactions involve the combination of different elements to form new compounds. Let's examine each reaction and identify the products:

a) Barium oxide (BaO) is formed when barium metal (Ba) reacts with oxygen gas (O2). The balanced chemical equation for this reaction is:

2 Ba + O2 → 2 BaO

b) Sodium chloride (NaCl) is formed when sodium metal (Na) reacts with chlorine gas (Cl2). The balanced chemical equation for this reaction is:

2 Na + Cl2 → 2 NaCl

c) Salt (NaCl) is formed when an acid reacts with a base. However, the specific acid and base involved in this reaction are not mentioned. Therefore, it is not possible to determine the exact product without additional information.

d) Potassium iodide (KI) is formed when potassium metal (K) reacts with iodine gas (I2). The balanced chemical equation for this reaction is:

2 K + I2 → 2 KI

e) Lithium oxide (Li2O) is formed when lithium metal (Li) reacts with oxygen gas (O2). The balanced chemical equation for this reaction is:

4 Li + O2 → 2 Li2O

Please note that the products mentioned above are based on the given reactions. If you have any additional information or specific reactants in mind, please let me know, and I'll be happy to assist you further.
