Answer: The formula unit of compound made up from Pb^{2+} and oxygen is PbO_2.

Explanation:

Pb^{4+}+O^{2-}\rightarrow PbO_2

When lead ion with '4+' charge binds with an oxygen anion with '2-'it forms lead(IV) oxide. The formula unit of the lead (IV) oxide according to criss cross method is written as PbO_2.

If 10.7 grams of NH4Cl is dissolved in enough water to make 800 mL of solution,what will be it's molarity
olga nikolaevna [1]
<h3><u>Answer;</u></h3>

Molarity = 0.25 M

<h3><u>Explanation;</u></h3>

Molarity is given by moles/Liter.

First we find moles:

Number of moles = Mass /molar mass

= (10.7g NH4Cl)/(53.5g/mol NH4Cl)

= 0.200 moles NH4Cl  

Then  we convert to liters:

= (800mL)*(1L/1000mL) = 0.800L  

Therefore; molarity = 0.2moles/0.8L

                                = 0.25M

Fittoniya [83]

Answer:

The correct answer is - D C2H4.

Explanation:

Saturated hydrocarbons are hydrocarbons with single covalent C-C bonds. They are known as alkanes. The general formula for these hydrocarbons is  CnH2n+2

Unsaturated hydrocarbons the hydrocarbons with double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is  CnH2n and CnHn-2

For the given options:

Option D: C2H4, is the simplest alkene with a double bond so it is an unsaturated hydrocarbon.

Calculate the solubility of cux(ksp=[cu2+][x2−]=1.27×10−36) in a solution that is 0.190 m in nacn.
nataly862011 [7]

if you have 1.27*10^-36= [Cu2+][X2-] then you can set both those values equal to x because they're stoichimetrically equal.

1.27*10^-36=x^2

Take the square root of both sides.

1.13*10^-18=x

That would be your solubility.
