To solve this problem we use Boyle's law to correlate the varying volume and pressure at constant temperature. Assuming ideal gas law, we use the equation P1/V1= P2/V2. Substituting, 735 mm Hg/ P2= 63.5 ml/69.2 ml. P2 is equivalent thus to 800.97 mm Hg.
25 miles/gallon should be the answer
hope this helped out hon :)
Catalytic Converter is the correct answer. Toxic gases are produced in the combustion reaction of an engine, and when this gas adheres to the converter, it’s chemically transmuted into something that’s harmless.
The reaction is at equilibrium at 1,000 K. The equilibrium constant of the reaction is 3.90. At equilibrium, the concentrations are as follows.
[CO] = 0.30 M
[H2] = 0.10 M
[H2O] = 0.020 M
What is the equilibrium concentration of CH4 expressed in scientific notation?
answer is b
El ácido sulfúrico es un ácido fuerte y por eso disocia completamente. La concentración de H+ será igual a la concentración de ácido sulfúrico (0.000475 M).
Para encontrar el pH, calcula -log[H+] = -log(0.000475) = 3.323
Para encontrar el pOH, sabes que pH + pOH = 14, y por eso pOH = 14 - pH = 14 - 3.323 = 10.677.
