The law that relate pressure and temperature of gases at constant volumes is Gay-Lussac's Law.

It states that the pressure of a fixed mass of gas is directly proportional to the absolute temperature when the volume is constant.

 P / T = constant => P1 / T1 = P2 / T2

=> P2 = T2 * P1 / T1

Remember that the formula uses absolute temperatures.

T2 = 52 + 273.15 = 325.15 K

T1 = 25 + 273.15 = 298.15 K

=> P2 = 325.15K * 3.00 atm / 298.15K = 3.27 atm.

Answer: 3.27 atm

Use calc to determine whether it is possible to remove 99.99% Cu2 by converting it to Cu(s) in a solution mixture containing 0.1
inessss [21]

Answer:

it is possible to remove 99.99% Cu2 by converting it to Cu(s)

Explanation:

So, from the question/problem above we are given the following ionic or REDOX equations of reactions;

Cu2+ + 2e- <--------------------------------------------------------------> Cu (s) Eo= 0.339 V

Sn2+ + 2e- <---------------------------------------------------------------> Sn (s) Eo= -0.141 V

In order to convert 99.99% Cu2 into Cu(s), the equation of reaction given below is needed:

Cu²⁺ + Sn ----------------------------------------------------------------------------> Cu + Sn²⁺.

Therefore, E°[overall] = 0.339 - [-0.141] = 0.48 V.

Therefore, the change in Gibbs' free energy, ΔG° = - nFE°. Where E° = O.48V, n= 2 and F = 96500 C.

Thus, ΔG° = - 92640.

This is less than zero[0]. Therefore,  it is possible to remove 99.99% Cu2 by converting it to Cu(s) because the reaction is a spontaneous reaction.

The empirical formula of a group of compounds is CHCl. Lindane, a powerful insecticide, is a member of this group. The molar mas
Sergeeva-Olga [200]

Answer:

<h2>D) 6</h2>

Explanation:

since,   n = molar mass / empirical formula mass

   Empirical formula mass = Total mass of atoms present in empirical formula

                       CHCl = 12+1+35.5

                                = 48.5

 Given, Molar mass = 290.8 g.

           So,        n = 290.8/48.5

                           = 5.995 , that is approx  6.

        So, Molecular formula = n × Empirical formula

                                           = 6 × CHCl

                                           = C_{6}H_{6}Cl_{6}

       So,   Number of C = 6

What is not a typical step when performing scientific research
Gelneren [198K]

The six steps of the scientific are:

1. State the question

2. Conduct research

3. Create a hypothesis

4. Perform the experiment

5. Analyze the data

6. Conclusion

So D. would be the correct answer, even though communicating the results could possibly be a step if it's required.
