What relationship exists between a homogeneous mixture and the number of phases in the mixture

Gwar [14]

The relationship that exists between a homogeneous mixture and the number of phases in the mixture is one phase.

Given that there is a relationship exists between a homogeneous mixture and the number of phases in the mixture.

We are required to tell the name of the relationship that exists between a homogenous mixture and the number of phases in the mixture.

A homogeneous mixture is basically a gaseous, liquid or solid mixture that has the same proportions of its components throughout a given sample.

The name of the relationship is one phase.

A phase is basically a relationship between the cycles of different periodic waves.

Hence the relationship that exists between a homogeneous mixture and the number of phases in the mixture is one phase.

Determine the empirical formula of a compound containing 47. 37 grams of carbon, 10. 59 grams of hydrogen, and 42. 04 grams of o

Effectus [21]

Considering the definition of empirical formula, the empirical formula is C₃H₈O₂ and the molecular formula is C₉H₂₄O₆.

<h3>Definition of empirical formula</h3>

The empirical formula is the simplest expression to represent a chemical compound, which indicates the elements that are present and the minimum proportion in whole numbers that exist between its atoms, that is, the subscripts of chemical formulas are reduced to the most integers. small as possible.

<h3>Empirical formula in this case</h3>

In this case, you have:

Carbon (C): 47.37 grams
Hydrogen (H): 10.59 grams
Oxygen (O): 42.04 grams

Then it is possible to calculate the number of moles of each atom in the molecule, taking into account the corresponding molar mass:

Carbon (C): $\frac{47.37 grams}{12 \frac{g}{mole} }$ = 3.95 moles
Hydrogen (H): $\frac{10.59 grams}{1 \frac{g}{mole} }$ = 10.59 moles
Oxygen (O): $\frac{42.04 grams}{16 \frac{g}{mole} }$ = 2.63 moles

The empirical formula must be expressed using whole number relationships, for this the numbers of moles are divided by the smallest result of those obtained. In this case:

Carbon (C): $\frac{3.95 moles}{2.63 moles }$ = 1.5
Hydrogen (H): $\frac{10.59 moles}{2.63 moles }$ = 4
Oxygen (O): $\frac{2.63 moles}{2.63 moles }$ = 1

Finally, since in the empirical formula the numbers of moles must be expressed in whole numbers, the ratio of atoms is multiplied by some number with which everything is obtained in simple whole numbers (in this case by 2):

Carbon (C): 1.5× 2= 3
Hydrogen (H): 4× 2= 8
Oxygen (O): 1× 2= 2

Therefore the C: H: O mole ratio is 3: 8: 2

Finally, the empirical formula is C₃H₈O₂.

<h3>Molecular formula</h3>

To obtain the molecular formula you must relate its molecular weight (PMc) with the molecular weight of the empirical formula (PMfe).

PMfe= PM (C₃H₈O₂)= 76 g/mole

The molar mass of the compound (PMc) was determined to be 228.276 g/mol. Dividing this mass PMc by the molar mass of the empirical formula PMfe gives:

228.276 g/mol ÷ 76 g/mole= 3

This means that in the molecular formula there are 3 unit formulas (empirical formulas), so it is necessary to multiply the number of all atoms by 3.

Then, the molecular formula is C₉H₂₄O₆.

Read the following scene from the inheritors. Fred jordan's cell. Slowly, at the end left unchalked, as for a door, she goes in.

Nadya [2.5K]

One of the disadvantages of watching the scene rather than reading it is the difficulty in interpreting the movements in the absence of stage directions.

<h3>What are stage directions?</h3>

They are instructions.
Show how actors must express their characters through movements and behaviors.
They show how the scenario should be set.

The stage directions shown in the text above show how actors should move through stage directions. This is shown in detail and specifies that it can be missed if the scene is watched and not read.

More information on stage directions is at the link:
