Consider the reaction between no and cl2 to form nocl: 2no(g)+cl2(g)⇌2nocl(g) a reaction mixture at a certain temperature initia
AlladinOne [14]

Answer:

Kc = 0.402.

Explanation:

  • We can calculate Kc from the relation: Kc = [NOCl]² / [NO]²[Cl₂].
  • [NOCl] = 0.30 M, [NO] = 0.65 M, and [Cl₂] = 0.53 M.
  • Now, we can get Kc:
  • Kc =  [NOCl]² / [NO]²[Cl₂] = (0.30 M)² / [(0.65 M)².(0.53 M)] = 0.402.

Why are numbers in chemistry expressed in scientific notation?
stiv31 [10]
Numbers in chemistry are often expressed in scientific notation because the numbers involved are either too large or too small. Scientific notation is a system in writing or working with numbers that would make it much easier to deal with. For instance, you have 1200000000000000, by looking at the number it would be tedious to write this again an again. So, we would opt to writing it in its scientific notation which would be 1.2x10^15.

What is the ph of a 0.010 m triethanolammonium chloride, (hoc2h2)3nhcl, solution?
azamat

The answer is 4.89


The explanation:


when the Kb of ((HOC2H2)3N) = 5.9 x 10^-7


1- we can get the value of Ka from Kb:


when Ka = Kw / Kb


= 1 x 10^-14 / 5.9 x 10^-7


= 1.69 x 10^-8


2- now we will calculate the [H+] value:


when [H+] = √(Ka*[HA])


=√((1.69E-8)(0.010))


= 1.3 x 10^-5 M


3- the final step we will calculate the PH value from the value of [H+]:


PH = - ㏒ [H+]


= - ㏒ 1.3 x 10^-5


= 4.89
