What attractive forces must be overcome when CsI is dissolvedin liquid HF?

Chemistry
1 answer:
bagirrra123 [75]3 years ago
4 0

Answer:

The attractive forces must be overcome are :

  • Ion- ion interaction
  • Dipole - Dipole  
  • Hydrogen Bonding  

Explanation:

For the compound to dissolve the attractive forces existing between atoms of the compound must be reduced

<u>CsI is ionic compound </u><em>and its molecules are held together by ionic(electrostatic) force . These force must be weakened for its dissolution</em>

Forces in HF <em>:</em>

<em>1 .Hydrogen Bonding :  In HF strong intermolecular Hydrogen Bonding exist between the electronegative F and Hydrogen</em>

2. Dipole - dipole : <em>HF is polar . So it is a permanent dipole and has dipole diople interaction</em>

A student observed a blue
morpeh [17]

Answer:

Color.

Explanation:

Hello,

In this case, since matter has a lot of properties regarding its physical condition and chemical composition, those related to the appearance of matter are physical. In such a way, since the student observed to different substances with also different colors, we can infer that the property of matter that was observed in the scenario was color, which accounts for the graphical perception we have from them.

Best regards.

Type the correct answer in the box. Express your answer to two significant figures. An industrial vat contains 650 grams of soli

The Balance Chemical Equation is as follow,

                                  2 HCl + Pb(NO₃)₂     →    2 HNO₃ + PbCl₂

According to equation,

          331.2 g (1 mole) Pb(NO₃)₂ produces  =  278.1 g (1 mole) PbCl₂

So,

                 870 g of Pb(NO₃)₂ will produce  =  X g of PbCl₂

Solving for X,

                     X  =  (870 g × 278.1 g) ÷ 331.2 g

                     X  =  730.5 g of PbCl₂

Therefore,

               Theoretical Yield =  730.5 g

Also as given,

                Actual Yield =  650 g

So using following formula for percentage yield,

                        %age Yield  =  (Actual Yield / Theoretical Yield) × 100

Putting values,

                        %age Yield  =  (650 g / 730.5 g) × 100

                        %age Yield  =  88.98 %

2. What is the molarity of 100 mL of a 3.0% H2O2 (mass/volume) solution? What is the molarity of 100 mL of a 2.25% H2O2 solution
KatRina [158]

The 3% mass/volume H₂O₂ means 3 g of H₂O₂ in 100 ml of water.

Now, Molarity (M) = No. of moles of H₂O₂ / Volume of solution in liter

No. of moles of H₂O₂ = Mass / Molar mass = 3 g / 34 g/mol = 0.088 mol

So, molarity = 0.088 × 1000 ml / 100 ml = 0.88 M

In case of 2.25 % H₂O₂,

No of moles = 2.25 g / 34 g/mol = 0.066 mol

Molarity = 0.066 mol / 0.100 L = 0.66 M.
