A physical property does not change the substance.
Solubility would be the answer since all of the rest are changing the substance. They all deal with bonds except solubility.
Answer: D. Solubility
Answer:
The reaction rate would decrease
Explanation:
The equation for the Haber process is given by;
N₂(g) + 3H₂(g) ⇆ 2NH₃(g)
- The reaction occurs at a temperature of 500°C
- Therefore, the forward reaction requires a temperature of 500°C.
- According to Le Chatelier's principle, if a factor affecting equilibrium is altered, the equilibrium will shift in the direction that counteracts the effect causing it.
- In this case, decreasing the temperature to 100°C will lower the rate of the forward reaction.
- Consequently, less ammonia gas will be produced as the reverse reaction is favored.
<u>Answer:</u> The pH of the solution is 1.41
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

Given mass of perchloric acid = 581.1 mg = 0.5811 g (Conversion factor: 1 g = 1000 mg)
Molar mass of perchloric acid = 100.5 g/mol
Volume of solution = 150 mL
Putting values in above equation, we get:

1 mole of perchloric acid produces 1 mole of
ions and 1 mole of
ions
To calculate the pH of the solution, we use the equation:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
We are given:
![[H^+]=0.0385M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.0385M)
Putting values in above equation, we get:

Hence, the pH of the solution is 1.41
T1 = 14⁰C = 273 +14= 287 K
T1 = 29⁰C =273 +29 = 302 K
V1 = 4.5 L
P = constant
T1/T2 = V1/V2
287/302 = 4.5/V2
V2= 302*4.5/287 = 4.7L
V2 = 4.7 L
