Answer:
Under the equilibrium condition
Explanation:
according to the phase rule given by Willard Gibbs, under the condition where the equilibrium between the number of phases is not affected by the gravity, electricity magnetic force or by surface action and the system is under constant temperature, pressure and concentration then the degrees of freedom(F) is proportional to the concerntration (C) and the Phases(P) at equilibrium condition.
the expression is given as : F= C-P+2
First, find how many copper atoms make up the ball:
<span>moles of atoms = (46.6 g) / (63.5 g per mol of atoms) = 0.73385 mol </span>
<span># of atoms = (0.73385 mol) (6.02 × 10^23 atoms per mol) = 4.4178 × 10^23 atoms </span>
<span>There is normally one electron for every proton in copper. This means there are normally 29 electrons per atom: </span>
<span>normal # electrons = (4.4178 × 10^23 atoms) (29 electrons per atom) = 1.2811 × 10^25 electrons </span>
<span>Currently, the charge in the ball is 2.5 µC, which means -2.5 µC worth of electrons have been removed. </span>
<span># removed electrons = (-2.5 µC) / (1.602 × 10^-13 µC per electron) = 1.5604 × 10^13 electrons removed </span>
<span># removed electrons / normal # electrons = </span>
<span>(1.5604 × 10^13 electrons removed) / (1.2811 × 10^25 electrons) = 1.22 × 10^-12 </span>
<span>That's 1 / 1.22 × 10^12 </span>
Answer:
A homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. We will look at three hydrocarbon series: alkanes, alkenes and the cycloalkanes. Hydrocarbons are compounds that contain only hydrogen and carbon.
