Final answer:
To predict the products of a chemical reaction, we need to understand the type of reaction taking place. Let's look at each reaction provided.
Step-by-step explanation:
To predict the products of a chemical reaction, we need to understand the type of reaction taking place. Let's look at each reaction provided:
a) MnCO3(s) + HI(aq): This is a double replacement reaction where the cations and anions switch partners. The products are MnI2(aq) + H2O(l) + CO2(g).
b) CoO(s) + O2(g): This reaction is a combustion reaction where a compound reacts with oxygen to produce carbon dioxide and water. The products are CO2(g) + Co2O3(s).
c) La(s) + O2(g): This is a synthesis reaction where two elements combine to form a compound. The product is La2O3(s).
