Why a increase in volume causes a decrease in pressure
Sergio [31]

Answer:

If pressure increases, then volume decreases and vice versa, when temperature is held constant.” When pressure increases, the same number of molecules, or matter, are being forced closer together to occupy a shrinking space, their volume decreasing while their density correspondingly increases.

Oxycodone (C18H21NO4), a narcotic analgesic, is a weak base with pKb = 5.47. Calculate the pH of a .00500 M oxycodone solution.
Ganezh [65]

Answer:

pH = 10.11

Explanation:

Hello there!

In this case, since it is possible to realize that this base is able to acquire one hydrogen atom from the water:

C_{18}H_{21}NO_4+H_2O\rightleftharpoons C_{18}H_{21}NO_4H^+OH^-

We can therefore set up the corresponding equilibrium expression:

Kb=\frac{[C_{18}H_{21}NO_4H^+][OH^-]}{[C_{18}H_{21}NO_4]}

Which can be written in terms of the reaction extent, x:

Kb=\frac{x^2}{0.00500M-x}=3.39x10^{-6}

Thus, by solving for x we obtain:

x_1=-0.000132M\\\\x_2=0.0001285M

However, since negative solutions are now allowed, we infer the correct x is 0.0001285 M; thus, the pOH can be computed:

pOH=-log(x)=-log(0.0001285)=3.89

And finally the pH:

pH=14-pOH=14-3.89\\\\pH=10.11

Best regards!

At a transform fault boundary
tiny-mole [99]

Answer:

Most of these faults are hidden in the deep ocean, where they offset divergent boundaries in short zigzags resulting from seafloor spreading, the best-known (and most destructive) being those on land at the margins of continental tectonic plates. A transform fault is the only type of strike-slip fault that is classified as a plate boundary.

How many joules are required to heat 2 l of water in a pot from 20 ◦c to the boiling point of water? the specific heat of water
miss Akunina [59]
  The  joules  required  to   heat 2L  of  water  in  a  pot  from  20  c  to  the  boiling  point  of  water  is  calculated     using the following  formula

  Q=    MC  delta  T
M  = mass  =   density  x   volume(  2  x 1000= 2000ml)
M  =     1g/ml  x2000  ml  =  2000g
C  =  specific  heat   capacity =  4.18  g/c
delta  T  =  change  in  temperature  =  100 c (  boiling  point  of  water)   -  20 c =  80 c 
Q  is therefore  =   2000 g x 4.18 j/g c  x  80c  =  668800j
