Answer:
The use of pomace for animal feed might be chosen if minimizing production costs is desired
Explanation:
i've taken the test
The use of pomace for animal feed might be chosen if minimizing production costs is desired. Therefore, the correct option is option D.
What is pomace?The solid byproduct of pressing grapes, olives, or even other fruits for juice or oil is known as pomace or marc. It includes the fruit's skins, pulp, seeds, or stems. Pomace brandy has traditionally been made from grape pomace. Currently, it is primarily used as fertilizer, animal feed, or to extract bioactive substances like polyphenols.
The Latin word "pomum" is where "pommace" comes from. The phrase "pomace" was first used by the English to describe the byproduct of making cider. Pomace wine, which had an alcohol concentration of three to four percent, was very common during the Middle Ages. The use of pomace for animal feed might be chosen if minimizing production costs is desired.
Therefore, the correct option is option D.

Calculate the percent yield of H3PO4 if 39.2 g of H3PO4 is isolated after carrying out the reaction.
percent yield:
%
The limiting reactant here is P4O10 . The percent yield of the product is caculated as 33.3%.
What is the limiting reactant?The limiting reactant is the reactant that is in a minute quantity.
Number of moles of P4O10 = 85.5 g/284 g/mol = 0.3 moles
Number of moles of H2O = 74.9 g / 18 g/mol = 4.2 moles
From the reaction equation;
1 mole of P4O10 reacts with 6 moles of H2O
x moles of P4O10 reacts with 4.2 moles of H2O
x = 0.7 moles
Hence, P4O10 is the limiting reactant.
1 mole of P4O10 yields 4 moles of H3PO4
0.3 moles of P4O10 yields
0.3 moles * 4/1 = 1.2 moles
Mass of the H3PO4 = 1.2 moles * 98 g/mol = 117.6 g
Percent yield = 39.2 g/117.6 g * 100/1 = 33.3 %

Based on the fgiven K_{a} values of the acids, the equilibrim concentrations of[tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex] is dtermined using ICE tables.
What are acid dissociatio constants [tex]K_{a}[/tex]?An acid dissociation constant, [tex]K_{a}[/tex] of an acid is a measure of the strength of the acid in solution. The larger the [tex]K_{a}[/tex] value of an acid, the stronger the acid, therefore, acid dissociation constants are usually apply to only weak acids because strong acids have exceedingly large [tex]K_{a}[/tex] values.
It is written as a qoutient of the equilibrium concentrations of the aqueous species in the acid solution.
[tex]K_{a} = \frac{[H^{+}] [A^-{}]}{HA}[/tex]For the weak acids such as [tex]HC_{2}H_{2}O_{2}[/tex] and [tex]NH_{4}^{+}[/tex], their equilibrim concentrations are determined using their [tex]K_{a}[/tex] values and an ICE table.
The pH of solutions are estimated using indicators such as methyl orange, methyl red and phenolphthalein. The colors of indicators change according to the pH of the solution
Acidic solutions have pH less than 7 while alkaline solutions have pH greater than 7.
Therefore, acids have low pH and weak acids have low [tex]K_{a}[/tex] values.

0.84(64)53.8gKevin and Lisa get into a deep discussion. Kevin believes adding HOT WATER to a test tube that has baking soda will cause the substances to react faster. Lisa, thinks he is wrong and believes that the HOT WATER may cause the substances to not react normally. Based on what you learned from the QUIZZIZZ ACTIVITY, whose side would you take in this argument????
I agree with idea of Kevin because bakong soda dissociates faster in hot water than cold water.
How baking soda reactivity increase in hot water?Baking soda is a chemical that can undergo a decomposition reaction when heated. At 80 degrees Celsius, sodium bicarbonate starts to break down into sodium carbonate (Na2CO3), water (H2O) and carbon dioxide (CO2) which is ready for reaction with other chemical.
So we can conclude that Kevin idea is correct because bakong soda dissociates faster in hot water than cold water.

You compare the gas generated from a reaction using two antacid tablets with the gas generated from a reaction using four antacid tablets (consider the antacid as the limiting reagent).
At constant pressure and temperature, how do the volumes of the gases compare?
The two reactions produce the same amount of gas.
The gas generated by four antacid tablets has a smaller volume.
The gas generated by two antacid tablets has a smaller volume.
Answer: The gas generated by two antacid tablets has a smaller volume.
Explanation:
Since the antiacid is the limiting reagent, we know that the more tablets there are, the more gas there will be.
This means that there will be more gas generated by the four antiacid tablets when compared to the two antiacid tablets, which gives us that the gas generated by the two antiacid tablets has a smaller volume.

Why is oxygen reduced in the reaction of hydrogen with oxygen to make water
Answer:
A. Oxygen pushes electrons towards the hydrogens.
Explanation:
The oxygen is reduced because it undergoes a partial gain of electrons. The oxygen atom in water has greater electron density near it than they did in the O₂ molecule.
What is Reduction Reaction ?
Reduction is a chemical reactions in which the number of electrons associated with an atom or a group of atoms is increased.
The electrons taken up by the substance reduced are supplied by another substance, which is thereby oxidized.
The hydrogen is oxidized because it added oxygen to form water.
Conversely the oxygen is reduced because it added hydrogen to form water.
Therefore, The oxygen is reduced because it undergoes a partial gain of electrons. The oxygen atom in water has greater electron density near it than they did in the O₂ molecule.
