I believe pH = -log[H+]

Also, 14 = pH + pOH

Therefore pH = 14 - pOH

pH = 14 - 4.01

pH = 9.99

9.99 = -log[H+]

Solve for H+

Which best explains why nuclear reactions release more energy than chemical reactions?
Leokris [45]
I think the best answer is the first statement. The forces holding the nucleus together are much stronger than the forces binding electrons to atoms. Breaking the former bonds are releases more energy than breaking bonds in a chemical reaction.

Ka  is  the  equilibrium  constant  for  the  ionization for a reaction. It  is  calculated  as  follows
ka  is equal  to (H3o ions)(A-) divided by (HA)
  2.00x106i s  equal  to 0.153x0.153 divided by ( HA)
  (2.00x106)HA is  equal  to  0.023409
  HA concentration  is  therefore equal to 0.023409/2.00x106 which  is 1.104x10^-4moles/litre

Part 1. Determine the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm. Show your work.
zaharov [31]

If a sample of gas is a 0.622-gram, volume of 2.4 L at 287 K and 0.850 atm. Then the molar mass of the gas is 7.18 g/mol

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases.

An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Given :

  • V = 2.4 L = 0.0024
  • P = 86126.25 Pa
  • T =  287 K
  • m = 0.622
  • R = 8.314

The ideal gas equation is given below.

n = PV/RT

n = 86126.25 x 0.0024 / 8.314 x 287

n = 0.622 / molar mass (n = Avogardos number)

Molar mass =  7.18 g

Hence, the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm is 7.18 g

More about the ideal gas equation link is given below.
