Answer: The value of equilibrium constant for the net reaction is 11.37
Explanation:
The given chemical equations follows:
Equation 1:
Equation 2:
The net equation follows:
As, the net reaction is the result of the addition of first equation and the reverse of second equation. So, the equilibrium constant for the net reaction will be the multiplication of first equilibrium constant and the inverse of second equilibrium constant.
The value of equilibrium constant for net reaction is:
We are given:
Putting values in above equation, we get:
Hence, the value of equilibrium constant for the net reaction is 11.37

How many grams in one mole of B2?
__g
Answers
Final answer:
The number of grams in one mole of B2 can be calculated using the atomic mass of element B. This is found on the periodic table and then doubled for B2 since it's diatomic. If B is Oxygen for instance, 1 mole of B2 (O2) weighs 32 grams.
Explanation:
To find the number of grams in one mole of B2, we need to know the atomic mass of element B, which isn't provided in your question. However, you can find this information on the periodic table. Once you have the atomic mass of B, you can calculate the molar mass of B2 (which is two times the atomic mass of B) since 1 mole of a substance corresponds to its molar mass in grams.
For example, if element B is Oxygen (O), its atomic mass is approximately 16 g/mol. Therefore, the molar mass of B2 (O2 in this case) would be 32 g/mol. Hence, 1 mole of B2 (or O2) would weigh 32 grams.

Answer:
There are approximately 475 umol of chlorogenic acid in the sample.
Explanation:
The first step is indentifying the chlorogenic acid structure. As it can be seen in the figure attached, this molecule is a carboxylic acid containing just one carboxyl group. This means, that chlorogenic acid is a monoprotic acid and it is only able to donate one proton per molecule or one mol of protons per one mol of molecules.
The second step is to balance the titration equation. Considering that sodium hydroxide will generate one mol of hydroxyl ions per mol of salt, we can simplify the equation:
H⁺ + OH ⁻ → H₂O
Therefore, we now know that for each mol of NaOH consumed 1 mol of chlorogenic acid is titrated.
Thus, the last step is calculation the amount of NaOH consumed during the tritation. We can use the following equation:
In which C is the concentration, n the amount of moles and V the volume.
The result is that n = 475 umol.

Final answer:
Energy spreads from its source in various ways depending on the type of energy. Heat travels through conduction, convection, and radiation, while mechanical energy like sound travels in waves.
Explanation:
In general, energy travels in all directions from its source depending on its type. For instance, heat energy propagates in a pattern called conduction, convection, or radiation. In conduction, it travels through the material in direct contact, like a metal spoon in a hot soup. Convection is the transfer of energy through fluids and gases, like warm air rising. While in radiation, energy moves in all directions in the form of electromagnetic waves, think sunlight or microwave radiation.
In the case of mechanical energy like sound, energy moves in waves outwards from a source, like sounds waves spreading after a drum is struck.

Final answer:
Energy travels in different ways depending on the context, which includes methods like conduction, convection, and radiation. Energy can also be transferred through work and it propagates in the direction of electromagnetic waves. In a star, energy transport is primarily through electromagnetic radiation and can travel in any direction.
Explanation:
Energy travels in different ways depending on the context. It can move through conduction, convection, and radiation. In conduction, energy transfers through molecules colliding with one another. In convection, energy gets transported through the currents of warm material rising towards cooler layers. In radiation, energy is conveyed through the movement of energetic photons from the hot material that gets absorbed by another material.
In addition, energy can be transferred through work, where a force exerted on an object in the direction of the object's motion transfers the energy. This can be seen when lifting a briefcase, where the exerted force does work on the briefcase, transferring energy to it. Furthermore, in the context of electromagnetic radiation, energy also propagates in the direction of the waves, where shorter, tighter waves carry more energy compared to longer, stretched-out waves.
Inside a star, unless convection occurs, the significant mode of energy transport is through electromagnetic radiation. In this case, a photon absorbed while traveling outward in a star might be radiated back toward the center of the star or towards its surface, indicating that energy can travel in any direction.
