Answer: The chemical equation is given below.

Explanation:

We are given a equation that represents ionization of barium nitrate salt.

Ionization reaction is defined as the reaction in which a salt breaks into its respective ions. The chemical equation for the ionization of barium nitrate is given as:

$Ba(NO_3)_2\rightarrow Ba^{+2}+2NO_3^-$

By Stoichiometry of the reaction:

1 mole of barium nitrate ionizes to produce 1 mole of barium ions and 2 moles of nitrate ions.

Hence, the chemical equation is given above.

Answer:

$1.2\times 10^{-2}$

Explanation:

The given reactions are:

PbCl2(aq)⇌Pb2+(aq)+2Cl−(aq) $K_3 = 1.89\times 10^{-10}$

AgCl(aq)⇌Ag+(aq)+Cl−(aq) $K_4 = 1.25\times 10^{-4}$

Required reaction is:

PbCl2(aq)+2Ag+(aq)⇌2AgCl(aq)+Pb2+(aq)

$K_f = \frac{K_3}{K_4^2}\\=\frac{1.89\times 10^{-10}}{1.25\times 10^{-4}}^2\\=1.2\times 10^{-2}$

Which is most likely true about electronegativity?

VikaD [51]

Electronegativity is the tendency of an element to attract the bonded electrons towards itself. In a group, as the atomic radius increases electronegativity decreases as the outermost electron is far away from the nuclear attraction. In a period, the atomic size decreases. So, the effective nuclear charge experienced by the outermost shell increases. Therefore, across a period the electronegativity increases as the increased effective nuclear charge leads to the attraction of bonded electrons with greater ease.

Therefore the correct answer is c, electronegativity tends to increases across a period.

How do you convert 250 mL into "cubic meters"? ? I'm confused because of the word "cubic". thanks

lakkis [162]

1000 liters equal to one cubic meter
so 250 ml is equal to 0.25 liters.

where it is 0.25 m cube
