What does the simplified model of the hall effect give for the density of free electrons in the unknown metal?

Chemistry

evablogger [386]2 years ago
3 0
The simplified model of the hall effect proved that the current (electric) in metals are carried by electrons and not protons. The hall effect introduced the hall coefficient which is the ratio of the induced electric field to the current density x applied magnetic field. This coefficient is unique for each type of metal.

ou discover that the complex decomposes in water. When 0.1000 g of the complex is dissolved in water with excess NaHg(SCN)4, all
Eduardwww [97]

Answer:

6.28x10⁻³ g

Explanation:

First we convert 0.1102 grams of CoHg(SCN)₄ into moles, using its <em>molar mass</em>:

  • 0.1102 g ÷ 491.9 g/mol = 2.24x10⁻⁴ mol CoHg(SCN)₄

There is 1 Co mol per CoHg(SCN)₄ mol, meaning there's also 2.24x10⁻⁴ moles of Co.

We now <u>convert 2.24x10⁻⁴ moles of Co into grams</u>, using its <em>molar mass</em>:

  • 2.24x10⁻⁴ mol Co * 28.01 g/mol = 6.28x10⁻³ g

How many moles of solute would be dissolved in .500 kg of solvent to make a 2.50 molal NaOH solution?
Tom [10]

Molality is a measure of concentration that relates the moles of solute to the kilograms of solvent, it is described by the following equation:

Molality=\frac{molSolute}{kgSolvent}

We are given the molality(2.50m) and kilograms of solvent(0.500kg), so we solve for moles of solute from the equation:

molSolute=Molality\times kgSolvent\begin{gathered} molSolute=2.50m\times0.500kg \\ molSolute=1.25molSolute \end{gathered}

To make a 2.50molal NaOH solution would be needed 1.25moles of solute

Answer: 1.25 moles
