If you mix Ammonia as well as Hydrogen chloride, you will get ammonium chloride. It is given by NH3 (g) + HCl (g) → NH4Cl(s).
This is an incomplete question, here is a complete question.
A 6.55 g sample of aniline molar mass = 93.13 g/mol) was combusted in a bomb calorimeter. If the temperature rose by 32.9°C, use the information below to determine the heat capacity of the calorimeter.
ΔH°rxn = -1.28 × 10⁴ kJ
Answer : The heat capacity of the calorimeter is,
Explanation :
First we have to calculate the moles of aniline.
Now we have to calculate the heat releases.
As, 4 mole of aniline on combustion to releases heat =
So, 0.0703 mole of aniline on combustion to releases heat =
Now we have to calculate the heat capacity of the calorimeter.
Thus, the heat capacity of the calorimeter is,
Answer:
V₂ = 1866.32 mL
Explanation:
Given data:
Initial temperature = 27.8°C (27 + 273.15 K = 300.15 k)
Initial volume = 1500 mL
Final volume = ?
Final temperature = 100.0°C (100.0 + 273.15 K = 373.15 K)
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
1500 mL / 300.15 k = V₂ / 373.15 K
V₂ = 1500 mL× 373.15 K/ 300.15 k
V₂ = 560175 mL. K /300.15 k
V₂ = 1866.32 mL
I think the answer should be True! Because the periodic law it states that the physical properties and chemical properties of their elements are periodic into the sequence of their atomic number.
Hope it helped!
