Answer:

The soilds vibrate in a fixed position and are very packed together whilst in liquids they are close together but they can move around and gases are widely spaced and move around randomly

Answer:

gas vibrate and move freely at high speeds. liquid vibrate, move about, and slide past each other. solid vibrate (jiggle) but generally do not move from place to place.

Iii. A sound wave can be modelled by using a slinky spring. A wavelength in this model is...

OLga [1]

Answer: d. the distance between two rarefactions,

Explanation:

Wavelength is the distance between two identical adjacent points in a wave. This means that it is the distance between two adjacent compressions or two adjacent rarefactions.

Wavelengths are inversely related to frequency because the longer the wavelength, the less the number of wave cycles per second.

The equilibrium constant has been estimated to be 0.12 at 25 °C. If you had originally placed 0.069 mol of cyclohexane in a 2.8

scZoUnD [109]

Answer: Concentrations of cyclohexane and methylcyclopentane at equilibrium are 0.0223 M and 0.0027 M respectively

Explanation:

Moles of cyclohexane = 0.069 mole

Volume of solution = 2.8 L

Initial concentration of cyclohexane = $\frac{moles}{Volume}=\frac{0.069}{2.8}=0.025M$

The given balanced equilibrium reaction is,

cyclohexane ⇔ methylcyclopentane

Initial conc. 0.025 M 0

At eqm. conc. (0.025-x)M (x) M

The expression for equilibrium constant for this reaction will be,

K= methylcyclopentane / cyclohexane

Now put all the given values in this expression, we get :

$0.12=\frac{(x)}{(0.025-x)}$

By solving the term 'x', we get :

x = 0.0027

Concentration of cyclohexane at equilibrium = (0.025-x ) M = (0.025-0.0027) M = 0.0223 M

Concentration of methylcyclopentane at equilibrium = (x ) M = (0.0027) M

chubhunter [2.5K]

Answer:

Explanation:

The physical methods of separating mixtures are used in sorting a mixture of substances.

It requires no chemical changes occurring between their components and parts in any significant way.

Examples are:

Decantation
Filtration
Sublimation
Magnetism
Centrifugation

The methods simply relies on the physical properties of matter.

An atom gets over all positive charge by ____ _______

Rasek [7]

<h2>Answer:</h2>

Nucleus.

<h2>Explanation:</h2>

In an atom the nucleus has an overall positive charge as it contains the protons.
Every atom has no overall charge (neutral). While atoms do contain charged particles, they have the same number of positive protons as negative electrons( for example a sodium atom has 11 electrons which are of negative charge and 11 protons which are of positive charge).
These opposite charges cancel each other out making the atom neutral.

Result: Nucleus is the overall positive charge of an atom.
