Answer: what are the choices?!.
Explanation:
Answer:
3rd option: AX + BY ⇒ AY + BX
Explanation:
The 2nd option is a single displacement reaction where one bound atom is displaced.
Logically, it would follow that a double displacemnt would be one where two bound atoms, i.e. X and Y, are displaced.
Answer:
Explanation:
Whenever a question asks you, "What is the concentration after a given time?" or something like that, you must use the appropriate integrated rate law expression.
The reaction is 2nd order, because the units of k are L·mol⁻¹s⁻¹.
The integrated rate law for a second-order reaction is
Data:
k = 2.4 × 10⁻²¹ L·mol⁻¹s⁻¹
[A]₀ = 0.0100 mol·L⁻¹
[A] = 0.009 00 mol·L⁻¹
Calculation

I’m taking a good estimation and gonna say B but I’m torn between that and D
According to Charles's Law, for a given mass of an ideal gas at constant pressure, the volume is directly proportional to its absolute temperature assuming in a closed system. Mathematical equation is : V1/T1=V2/T2. 87 degrees Celsius equals 87+273.15=360.15 k, and standard temperature is 273.15 k. So, 180/360.15 = V2/273.15, V2=180*273.15/360.15 = 136.52 mL, which is the volume of gas at standard temperature.
