Answer:
(e) -6.1 J/K
Explanation:
Step 1: Given data
- Heat of fusion of ice (ΔH°fus): 333.5 J/g
Step 2: Calculate the heat (Qfreezing) required to freeze 5.0 g of water
We will use the following expression.
Qfreezing = -ΔH°fus × m
Qfreezing = -333.5 J/g × 5.0 g = -1.7 × 10³ J
Step 3: Calculate the entropy change (ΔS°) at 0 °C (273.15 K) and 1 atm
We will use the following expression.
ΔS° = Qfreezing/T
ΔS° = -1.7 × 10³ J/273.15 K = -6.1 J/K
The pressure exerted when both gases are put together in a single 1 liter container is 5 atm.
<h3>What is pressure?</h3>
Pressure is the force exerted by any object on another object.
Given that, a and b separate 1 liter containers and exert pressure of 2 atm and 3 atm respectively.
When both gases a and b exert together, the pressure then
2 atm + 3 atm = 5 atm.
Thus, the pressure exerted when both gases are put together in a single 1 liter container is 5 atm.

Answer:
1.0 moles of N2
Explanation:
since
1.0 × avogadro's no# = same answer for SO2 and N2
avogadro's no#= 6.02× 10²³
To find the molecular formula of the compound, we get the molar mass of empirical formula CH2o which is 30 g/mol. We divided the molecular mass of 90.087 g/mol by 30, we get 3. Hence, we multiply each element by 3, getting the molecular formula of C3H6O3.
