Answer:
Explanation:
Hello,
In this case, the molar enthalpy of reaction is obtained by dividing the involved energy by the reacting moles:
Thus, it is important to notice that the compound "uses" the energy, it means that it absorbs the energy, for that reason the sign is positive. Moreover, computing the result in kJ/mol we finally obtain:
Best regards.
The ml is also called as the magnetic quantum number. The value
of ml can range from –l to +l including zero. Hence all of the possible values for ml given
that l = 2 are:
<span>-2, -1, 0, + 1, + 2</span>
<span>The correct answer is b. Boiling point, why? because the liquid sample of napthalene is heated and remained at the temperature of 218 degrees celsius, the outcome was that the napthalene was completely vaporized, therefore we are given the scenario that at the temperature of 218 degrees celsius is considered to be the boiling pont of napthalene.</span>
Its b Fe(s) <span> Fe</span>2+(aq) + 2e– <span><span> </span>E</span><span> = </span><span>+0.44 V</span>
Answer:
1.80 × 10²⁴ Molecules of Sucrose
Solution:
Number of Moles and Number of Particles (molecules in given case) are related to each other as,
Moles = Number of Molecules ÷ 6.022 × 10²³
Solving for Number of Molecules,
Number of Molecules = Moles × 6.022 × 10²³
Data Given;
Moles = 3 moles
Putting values in eq,
Number of Molecules = 3 mol × 6.022 × 10²³
Number of Molecules = 1.80 × 10²⁴ Molecules
