Convert 21 L CO2 to molecules PLEASE EXPLAIN DON'T JUST LEAVE AN ANSWER

Chemistry
1 answer:
Rasek [7]3 years ago
7 0
A common conversion factor is that 22.4 liters of a gas at STP is equal to one mole of that substance.

21 L / 22.4 L = 0.9375 moles of CO2

One mole of any substance contains an Avogadro’s number of atoms: 6.022 x 10^23 atoms/mol.

0.9375 mol x (6.022 x 10^23 atoms/mol) = 5.646 x 10^23 atoms of CO2

21 liters of CO2 contains 5.646 x 10^23 atoms of CO2.

Do anyone know how to do question B
Over [174]

Answer:

a) IUPAC Names:

                   1) (<em>trans</em>)-but-2-ene

                   2) (<em>cis</em>)-but-2-ene

                   3) but-1-ene

b) Balance Equation:

                       C₄H₁₀O + H₃PO₄   →   C₄H₈ + H₂O + H₃PO₄

As H₃PO₄ is catalyst and remains unchanged so we can also write as,

                                    C₄H₁₀O   →   C₄H₈ + H₂O

c) Rule:

           When more than one alkene products are possible then the one thermodynamically stable is favored. Thermodynamically more substituted alkenes are stable. Furthermore, trans alkenes are more stable than cis alkenes. Hence, in our case the major product is trans alkene followed by cis. The minor alkene is the 1-butene as it is less substituted.

d) C is not Geometrical Isomer:

        For any alkene to demonstrate geometrical isomerism it is important that there must be two different geminal substituents attached to both carbon atoms. In 1-butene one carbon has same geminal substituents (i.e H atoms). Hence, it can not give geometrical isomers.

Describe the relationship between soil formation and climate ?
stich3 [128]
If there is more soil, there would be more plants, and thus, more organisms, depending on if the soil has enough nutrients to support an ecosystem. The way that this would affect the climate is that it would transpire moisture into the atmosphere, and also generate fresher air through photosynthesis.

Which of the following is true about the melting temperature of potassium chloride? The melting temperature is relatively high.
allochka39001 [22]

Answer:f

  • First option: <em>the melting temperature is relatively high.</em>

Explanation:

You can look at the melting temperature at any table that summarizes the main properties of this compound, <em>potassium chloride</em>.

Such melting point is 770 °C, which is relatively high.

<u>Why is this?</u>

Potassium chloride is a ionic compound formed by the cations of potassium, K⁺, and the chloride anions, Cl⁻. Its unit formula is KCl.

The ionic bond between K and Cl is possible because each K atom is able to yield its valence electron to one Cl atom which has 7 valence electrons.

Then, the K atoms become positive ions (cations) K⁺, while Cl atoms become negative ions (Cl⁻).

These two ions with opposite charge are bonded by the force of electrostatic attraction. This is a ionic bond.

<em>Melting point</em>, so as boiling point along with other physical properties, depends on the attraction force between the atoms.

Hence, since the attrative forces between the ions are relatively strong, the <em>melting point</em> of the ionic compounds, such as potassium chloride, are <em>relatively high.</em>
