Predict the following reaction Kl+Pb(NO3)2->?

Chemistry
1 answer:
Nonamiya [84]3 years ago
6 0

Answer:

The answer to your question is KNO₃  +  PbI₂

Explanation:

Data

Chemical reaction

                      KI  +  Pb(NO₃)₂  ⇒  

Process

We know that this is a double displacement reaction because there are two reactants and each reactant has a cation and an anion (a positive atom and a negative atom or a polyatomic molecule).

To know the products just interchange the cations in each molecule considering the oxidation numbers.

                          K⁺¹I⁻¹  +  Pb⁺²(NO₃)₂⁻¹  ⇒   K⁺¹NO₃⁻¹ + Pb⁺² I₂⁻¹

or

                          KI  +  Pb(NO₃)₂  ⇒  KNO₃  +  PbI₂

2.5 moles of sodium chloride is dissolved to make 0.050 liters of solution
Hitman42 [59]

The answer is:

the molarity = 50 moles/liters

The explanation:

when the molarity is = the number of moles / volume per liters.

and when the number of moles =2.5 moles

and the volume per liters = 0.05 L

so by substitution:

the molarity = 2.5moles/0.05L

                    = 50 moles /L

How would you prepare 1.00 L of a 0.50 M solution of each of the following?
Lunna [17]

Answer:

Take approx 41.7 mL of 12-M HCl in a 1.00-L flask and fill the rest of the volume with distilled water.

Explanation:

Hello,

In this case, for the dilution process from concentrated  12-M hydrochloric acid to 1.00 L of the diluted 0.50M hydrochloric acid, the volume of concentrated HCl you must take is computed by considering that the moles remain constant for all dilution processes as shown below:

n_1=n_2

Which can also be written in terms of concentrations and volumes:

M_1V_1=M_2V_2

Thus, solving for the initial volume or aliquot that must be taken from the 12-M HCl, we obtain:

V_1=\frac{M_2V_2}{M_1} \\\\V_1=\frac{1.00L*0.5M}{12M}\\ \\V_1=0.0417L=41.7mL

It means that you must take approx 41.7 mL of 12-M HCl in a 1.00-L flask and fill the rest of the volume with distilled water for such preparation.

Best regards.
