Answer:
1.04 mol
Explanation:
CO₂ is produced in a closed 100 L vessel according to the following equation.
CaCO₃(s) ⇄ CaO(s) + CO₂(g)
At equilibrium, the pressure of carbon dioxide remains constant at 1.00 atm.
First, we need to conver the temperature to the absolute scale (Kelvin scale) using the following expression.
K = °C + 273.15
K = 898°C + 273.15
K = 1171 K
Now, we can find the moles of carbon dioxide using the ideal gas equation.

Heating a gas increases the kinetic energy of the particles, causing the gas to expand. In order to keep the pressure constant, the volume of the container must be increased when a gas is heated.
Answer:
a. 0.5dm³
b. 5x10⁻³dm³
Explanation:
a. A solution that is 4mol/dm³ contains 4 moles in 1dm³. The volume that contains 2 moles is:
2 moles * (1dm³ / 4mol) =
<h3>0.5dm³</h3><h3 />
b. And for the 6 mol/dm³ containing 0.03moles:
0.03 moles * (1dm³ / 6mol) =
<h3>5x10⁻³dm³</h3>
Answer:
Explanation:
During the seventeenth and especially eighteenth centuries, driven both by a desire to understand nature and a quest to make balloons in which they could fly (Figure 1), a number of scientists established the relationships between the macroscopic physical properties of gases, that is, pressure, volume, temperature, and amount of gas. Although their measurements were not precise by today’s standards, they were able to determine the mathematical relationships between pairs of these variables (e.g., pressure and temperature, pressure and volume) that hold for an ideal gas—a hypothetical construct that real gases approximate under certain conditions. Eventually, these individual laws were combined into a single equation—the ideal gas law—that relates gas quantities for gases and is quite accurate for low pressures and moderate temperatures. We will consider the key developments in individual relationships (for pedagogical reasons not quite in historical order), then put them together in the ideal gas law
