Carbonic acid undergoes decomposition reaction. Decomposition reaction starts with one reactant and forms two or more products: AB⇒A+B. In this reaction, H2CO3 ⇒H2O + CO2.
Sodium is a very reactive metal. It is kept in kerosene to prevent it from coming in contact with oxygen and moisture. If this happens, it will react with the moisture present in air and form sodium hydroxide.
<span>Platinum is solid at room temperature. SInce the catalyst is solid while the medium involves gases, this catalyst is characterized as heterogenous. Because they are different states of matter, they can be easily separated through physical means. So, the answer is B.</span>
Answer:
1. 504.8 g Al(NO3)3
2. 14.3 moles O2
Explanation:
1.
g = moles x molar mass = 2.37 x 212.996 = 504.8 g Al(NO3)3
MM Al(NO3)3 = 212.996 g/mol
2.
moles = mass : molar mass = 456.89: 32 = 14.3 moles O2
A. More reactants could have been added to reaction B
