The dissociation of calcium carbonate, CaCO3, to simpler compounds can be expressed as,
CaCO3 --> CaO + CO2
The precipitate is CaO and its amount is calculated through the difference which will give us the answer of 5.6 g.

Answer: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

Answer:
The new volume of the gas is 4.74L
Explanation:
Data;
T1 = 14°C = (14 + 273.15)K = 287.15K
V1 = 4.5L
T2 = 29°C = (29 + 273.15)K = 302.15
V2 = ?
From Charles law,
The volume of a fixed mass of gas is directly proportional to its temperature provided that pressure remains constant.
Mathematically,
V = kT
k = V1 / T1 = V2 / T2 = V3 / T3 = .............= Vn / Tn.
V1 / T1 = V2 / T2
Solving for V2
V2 = (V1 * T2) / T1
V2 = (4.5 * 302.15) / 287.15
V2 = 4.735L
V2 = 4.74L
The new volume of the gas is 4.74L
