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

The reactants of two chemical equations are listed. Equation 1: PbNO3 + Mg Equation 2: PbNO3 + KI Based on the type of reaction,
Vika [28.1K]

Answer:

Equation 2, because K being more reactive, exchanges position with Pb in PbNO3.

Explanation:

Hello there!

In this case, according to the given reactions, it is possible to realize that according to the reactivity series, since K is is group 1A of alkali metals, we infer it is by far more reactive than magnesium, for that reason last two choices can be easily discarded. Now, considering equation 2, it would be necessary to complete it to figure out the correct option:

Pb(NO_3)_2 + KI \rightarrow PbI_2+KNO_3

Whereas it can be seen that potassium exchanges position with Pb according to the double displacement reaction; therefore, the correct answer is "Equation 2, because K being more reactive, exchanges position with Pb in PbNO3".

Best regards!

What is the concentration of the base (KOH) in the following titration, given the data below?
Anettt [7]
To calculate the concentration of the base based on the titration, the concept used is the equal of number of equivalence of the acid used to that of the base. From this,
                                 Na x Va = Nb x Vb
For HBr and KOH, molarity is equal to normality. Substituting the known values,
          (0.75 M) x (22.6 mL - 0 mL) = Nb x (37.5 mL - 0.5 mL) 
                                         Nb = 0.46 N
                                          Mb = 0.46 M
Thus, the concentration of the base is approximately 0.46 M.
