A calorimeter contains 31.0 mL of water at 13.5 ∘C . When 2.30 g of X (a substance with a molar mass of 76.0 g/mol ) is added, it dissolves via the reaction X(s)+H2O(l)→X(aq) and the temperature of the solution increases to 29.5 ∘C . Calculate the enthalpy change, ΔH, for this reaction per mole of X. Assume that the specific heat of the resulting solution is equal to that of water [4.18 J/(g⋅∘C)], that density of water is 1.00 g/mL, and that no heat is lost to the calorimeter itself, nor to the surroundings. Express the change in enthalpy in kilojoules per mole to three significant figures.
Answers
Answer:
-73.6kJ/mol
Explanation:
The solution is increasing its temperature from 13.5°C to 29.5°C, that means the enthalpy change is < 0
The released heat is determined using the calorimeter equation:
Q = -C×m×ΔT
Where Q is heat,
C is specific heat of the solution (4.18J/g°C)
m is mass of the solution (31.0mL = 31.0g + 2.30g = 33.3g)
And ΔT is change in temperature (29.5°C - 13.5°C = 16°C)
Replacing:
Q = -4.18J/g°C×33.3g×16°C
Q = -2227J are released
This heat is released when 2.30g are dissolved, that is:
-2227J / 2.30g × (76.0g / mol) = -73591J/mol =

A
Metals generally have higher electronegativity than nonmetals in the same period.
B
Nonmetals generally have a lower, first-ionization energy than metals in the same period.
с
Metals generally have smaller radii than nonmetals in the same period.
D
Nonmetals generally have a higher electronegativity than metals in the same period.
Answers
Answer:
D.) Nonmetals generally have a higher electronegativity than metals in the same period.
Explanation:
A.) is incorrect because within the same period, nonmetals have the higher electronegativity values.
B.) is incorrect because ionization energy usually increases as one goes across the periodic table, meaning metals will generally have lower, first-ionization energies. This is because the protons in the atoms increase as you travel across the periodic table while the outer shell continues to occupy the same energy level. The more protons there are, the greater the attraction between the electrons and protons, making it more difficult to ionize the atom.
C.) is incorrect because within the same period, nonmetals will have the smaller radii. This is because as you go across a period, the protons in the atom increase. The more protons there are, the greater the pull they will have on their electrons. This shrinks the size of the atom.
D.) is correct because as you go across a period, the electronegativity increases. These atoms are more likely to attract electrons due to their higher proton count while simultaneously being a smaller size.

You received an unsolicited proposal from a self-declared inventor who is seeking investors for the development of his latest idea: a device that uses heat extracted from the ground by a heat pump to boil water into steam that is used to heat a home and to power a steam engine that drives the heat pump. This procedure is potentially very lucrative because, after an initial extraction of energy from the groin, no fossil fuels would be required to keep the device running indefinitely. Would you invest in this idea? State your conclusion clearly and present detailed arguments to support it.
Answers
Answer: Yes
Explanation:
Yes, i would invest in this idea, Because the procedure looks very lucrative. Because the initial extraction of the energy from the ground requires no fossil fuel to keep the device running or in operation, rather the heat extracted would be used to heat a heat pump which would boil into steam and in turn used to drive a or power a steam engine.

When a 16.8 mL sample of a 0.410 M aqueous hydrocyanic acid solution is titrated with a 0.408 M aqueous sodium hydroxide solution, what is the pH after 25.3 mL of sodium hydroxide have been added?
pH =
Answers
From the calculations and results obtained, the pH of the solution is 12.85. This implies that the solution is basic or we can say it is alkaline.
What is pH?pH is a scale that shows the acidity or alkalinity of a solution.
Number of moles of hydrogen cyanide = 0.410 M * 16.8 /1000 L = 0.0069 moles
Number of moles of NaOH = 0.408 M * 25.3/1000 L = 0.01 moles
Since the reaction is 1:1, hydrogen cyanide is the limiting reactant.
Number of moles of NaOH left over = 0.01 moles - 0.0069 moles
= 0.0031 moles
Total volume = 16.8 mL + 25.3 mL = 42.1 mL or 0.042 L
Molarity of left over hydroxide ions = 0.0031 moles /0.042 L
= 0.07 M
pOH = - log(0.07 M) = 1.15
pH = 14 - 1.15 = 12.85

If the pH of an acid rain storm is approximately 3.0, how many times greater is the [H ] in the rain than in a cup of coffee having a pH of 5.0
Answers
Taking into account the definition of pH, the [H⁺] in the rain is 100 times greater than in a cup of coffee.
Definition of pHpH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.
Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:
pH= - log [H⁺]
The numerical scale that measures the pH of substances includes the numbers from 0 to 14. The pH value 7 corresponds to neutral substances. Acidic substances are those with a pH lower than 7, while basic substances have a pH higher than 7.
Comparison of [H⁺]In this case, you know:
pH= 3pH= 5You can replace this values in the definition of pH:
3= -log [H⁺] → [H⁺]=1×10⁻³ M5= -log [H⁺] → [H⁺]=1×10⁻⁵ MSolving:
[H⁺]=1×10⁻³ M[H⁺]=1×10⁻⁵ MComparing [H⁺], you get:
[tex]\frac{1x10^{-3} }{1x10^{-5} } =100[/tex]
Finally, the [H⁺] in the rain is 100 times greater than in a cup of coffee.
