How do intermolecular forces determine molecular arrangement in solids?

1 answer:

8 0

I think the best answer to this is when the object is in high temperature and intense pressure that could make the molecule move and active. I hope you are satisfied with my answer and feel free to ask for more if you have further question and clarification.

Answer:

You find a separatory funnel set up in a fume hood. There are clearly two visible layers. Describe a method you could use to determine which layer is the aqueous layer.

Explanation:

In the separating funnel, the liquid with less density exists at the top layer and the liquid with greater density will exist at the bottom layer.

To identify the aqueous layer, add a bit of water to the separating funnel.

Then, observe where the water will go and mix.

If it mixes with the bottom layer, then the bottom layer is the aqueous layer.

If water mixes with the top layer, then top layer is the aqueous layer.

Answer: Nail moving towards a magnet

Explanation: Since the iron nails and pins move towards the magnet, it means that the magnet exerts a force on them. The force exerted by a magnet is called magnetic force.

What is the standard potential, e∘celle∘cell, for this galvanic cell? use the given standard reduction potentials in your calcul

Olin [163]

The standard potential for the given galvanic cell is 0.477 V

<h3>What is electrode potential?</h3>

The electrode potential is the electromotive force of a galvanic cell built using a standard reference electrode and another electrode whose potential is to be found.

There are two types of electrode potential

Oxidation potential - The potential associated with oxidation reaction is known as oxidation potential

Reduction potential - The potential associated with reduction reaction is known as reduction potential

At the anode, oxidation occurs

$Sn(s)\rightarrow Sn^{2+}(aq)+2e^-$

At the cathode, reduction occurs

$Cu^{2+}(aq)+2e^-\rightarrow Cu(s)$

$E^o_{cell} =E^o_{cathode} -E^o_{anode}$

= 0.337 - (-0.140)

= 0.477 V

Thus, The standard potential for the given galvanic cell is 0.477 V

How many molecules are contained in 1.55 moles of methane, CH 4 ?

Korolek [52]

Avogadro's law states that in one mole of a substance, there are $6.022 \times 10^{23}$ molecules.

This means that in 1.55 moles, there are $1.55(6.022 \times 10^{23})=\boxed{9.33 \times 10^{23} \text{( to 3 sf)}}$
