Answer:
Decomposition or cracking
Explanation:
In a decomposition or cracking reaction, a single compound produces two or more simpler substances.
It involves the formation of two or more products from a single reactant.
A → B + C
A is the single reactant
B and C are the products
The driving force for such a reaction is the is high positive heat of formation of the compound that is, extreme instability of the compound.
Answer:
3.96 × 10⁻³ mol Pb
Explanation:
Step 1: Find molar mass
Pb (Lead) - 207.2 g/mol
Step 2: Use Dimensional Analysis
= 0.003962 mol Pb
Step 3: Simplify
We have 3 sig figs
0.003962 mol Pb ≈ 0.00396 mol Pb
0.00396 mol Pb = 3.96 × 10⁻³ mol Pb
