If the initial concentration of a is 0.00540 m, what will be the concentration after 795 s?
zavuch27 [327]
<span>Feb 19, 2014 - The units of k tell you that this is a second order reaction. So, to solve this, you need to use the integrated rate law for a 2nd order reaction: 1/[A] = kt + 1/[A]o 1/[A] = 0.540/Ms (835 s) + 1/0.00640 1/[A] = 607 [A] = 1.65X10^-3 M.</span><span>

List any two types of mixtures that are not covered in the Exploration. Also mention the state
marishachu [46]

This question is incomplete because you lack the options. But it can be answered based on my knowledge.

Two types of mixture could be: homogeneous and heterogeneous

A mixture is a term that refers to the combination of two or more components joined but not chemically combined. Mixtures can be classified as follows:

  • Homogeneous: Are characterized by having a uniform texture and appearance, their components are not distinguished.
  • For example: water + grapes = wine

Homogeneous mixtures can be:

  • Solutions: The mixtures formed are characterized by being formed with components that do not react chemically with each other, but that can modify their physical properties when they become part of the solution.
  • For example: coffee + milk = Coffee

There are also Colloids, a type of mixture formed by particles of one or more substances that are dispersed in another substance called a dispersing medium.

  • For example Gelatin powder + Water = Gelatin.

They are the intermediate mixtures between homogeneous and heterogeneous.

  • Heterogeneous: Are mixtures in which it is possible to observe their components due to the discontinuity with the naked eye.
  • For example Milk + cereal = Cereal
