If 75 g. of Potassium Chloride (ionic compound) is dissolved in 250 grams of
water, what will be the freezing point of the solution? Kf = 1.86
Answers
Answer:
[tex]T_{f,sol}=-15.0\°C[/tex]
Explanation:
Hello there!
In this case, for these problem about the colligative property of freezing point depression, it is possible set up the following equation:
[tex]T_{f,sol}-T_{f,water}=-i*m*Kf[/tex]
Whereas the van't Hoff's factor, i, is 2 since KCl is ionized in two ions (K+ and Cl-); and the molality (m) of the solution is computed by:
[tex]m=\frac{75g*\frac{1mol}{74.55g} }{250g*\frac{1kg}{1000g} } \\\\m=4.02mol/kg[/tex]
Thus, since the freezing point of water (ice) is 0°C, we obtain the following freezing point of the solution by plugging in:
[tex]T_{f,sol}=-(2)(4.02mol/kg)(1.86\°C/mol*kg)\\\\T_{f,sol}=-15.0\°C[/tex]

Explanation:
Hello there!
In this case, according to the given reactants, it is firstly necessary to set up the complete molecular reaction:
[tex]NH_4OH(aq)+HClO_4(aq)\rightarrow NH_4ClO_4(aq)+H_2O(l)[/tex]
Now, by knowing that ionic species are able to ionize, we are able to write the complete ionic equation:
[tex]NH_4^++OH^-+H^++ClO_4^-\rightarrow NH_4^++ClO_4^-+H_2O(l)[/tex]
Whereas ammonium and chlorate ions are spectator ions because they remain the same on both sides of the equation. Therefore the total or net ionic equation would be:

What is absorption spectra?The term "absorption spectroscopy" applies to spectroscopic methods that assess how much radiation interacts with a sample and is absorbed as a proportion of frequency or wavelength. The sample takes in photons, meaning energy, from the emitting field.
What are electrons?The electron would be a subatomic particle with a negative one fundamental charge electric charge. Due to their lack of components or substructure, electrons, which have become part of the lepton particle family's first generation, could be typically regarded to be elementary particles.
The percentage of incoming electromagnetic energy that a material absorbs across a variety of frequencies is displayed in the material's absorption spectrum. In a way, an emission spectrum would be the converse of an absorption spectrum.

Answers
Answer:
3 m
Explanation:
We'll begin by converting 99.9 MHz to Hz. This can be obtained as follow:
1 MHz = 10⁶ Hz
Therefore,
99.9 MHz = 99.9 MHz × 10⁶ Hz / 1 MHz
99.9 MHz = 99.9×10⁶ Hz
Finally, we shall determine the wavelength. This can be obtained as follow:
Frequency (f) = 99.9×10⁶ Hz
Velocity (v) = 3×10⁸ m/s
Wavelength (λ) =?
Velocity = wavelength × frequency
v = λf
3×10⁸ = λ × 99.9×10⁶
Divide both side by 99.9×10⁶
λ = 3×10⁸ / 99.9×10⁶
λ = 3 m
Thus, the wavelength of the electromagnetic wave is 3 m.

Graphite, an allotrope of carbon, is converted into cubic diamond through a process that may take a billion years or longer. As illustrated above, scientists can make synthetic diamonds using a certain process in about one week. However, these synthetic diamonds have carbon atoms in a hexagonal lattice. Diamonds with a carbon atoms in a cubic lattice are not produced even though they are thermodynamically more stable than hexagonal diamond. Which of the following best justifies why the synthetic process produces hexagonal diamond and not the more thermodynamically stable cubic diamond?
a. The amount of energy required to create new bonds between carbon atoms in cubic diamond is much greater than the amount of energy required to create hexagonal diamond.
b. The amount of energy required to create new bonds between carbon atoms in cubic diamond is much smaller than the amount of energy required to create hexagonal diamond.
c. The activation energy needed to form cubic diamond is much less than the activation energy needed to form hexagonal diamond.
d. The activation energy needed to form cubic diamond is much greater than the activation energy needed to form hexagonal diamond.
Answers
Answer:
The activation energy needed to form cubic diamond is much greater than the activation energy needed to form hexagonal diamond.
Explanation:
The activation energy refers to the minimum energy that reacting species must possess before they can undergo a particular chemical reaction.
This implies that if species do not possess the activation energy, they hardly undergo a given reaction. The activation energy is the barrier between reactants and products.
Hence, a reaction that has a very high activation energy occurs slowly or may not even occur. The activation energy needed to form cubic diamond is much greater than the activation energy needed to form hexagonal diamond hence the synthetic process produces hexagonal diamond and not the more thermodynamically stable cubic diamond.
