When 92.0 g of ethanol (c2h5oh are vaporized at its boiling point of 78.3°c, it requires 78.6 kj of energy. what is the approxim
Juli2301 [7.4K]

The solution would be like this for this specific problem:

<span>(78.6 kJ) / (92.0 g / (46.0684 g C2H5OH/mol)) = 39.4 kJ/mol </span>

<span>39.3 </span>

So the approximate molar heat of vaporization of ethanol in kJ/mol is 39.3.

I hope this answers your question.

How many atoms of calcium, Ca would be equal to 5.472 X 104 moles Ca?
Montano1993 [528]
Answer:
             3.29 × 10²⁸ Atoms

Solution:
              Moles and Number of atoms are related to each other as,

                           Moles  =  Number of Atoms / 6.022 × 10²³   ------- (1)

Data Given;
                  Moles  =  5.472 ×10⁴

                  Number of Atoms  =  ?

Solving eq. 1 for Number of Atoms,

                        Number of Atoms  =  Moles  × 6.022 × 10²³

Putting values,

Number of Atoms  =  5.472 ×10⁴ mol × 6.022 × 10²³ atoms.mol⁻¹

Number of Atoms  =  3.29 × 10²⁸ Atoms

Balance the following chemical reaction: _NaOH + _H2SO4 -----&gt;_Na2SO4 +_H20
Dima020 [189]

Answer:

Sodium Hydroxide + Sulfuric Acid = Sodium Sulfate + Water

2NaOH + H2SO4 → Na2SO4 + 2H2O

Explanation:

To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.

Ionic charges are not yet supported and will be ignored.

Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.

Compound states [like (s) (aq) or (g)] are not required.

You can use parenthesis () or brackets [].

Explain how astronomers use spectrographs to identify the composition of a star.
Gwar [14]
Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.
hope this helps you! :-)
