Find the pOH for the following:
A 1.34 x 10^-4 M solution of hydrochloric acid.
A) 10.13
B) 3.87
C) 4
D) 10
Answer:
A) 10.13 is the answer
Explanation:
Since HCl is a strong acid, its pH can be found by simply plugging it into the equation:
pH = -log[H+]
*H+ is just the concentration you were given*
Now that you have the pH, you just subtract it from 14 to find the pOH
I have attatched my work below. Hope this helps! :^)
To find the pOH of a solution, you can use the formula: pOH = -log10[OH-]
What is pOH?pOH is a measure of the concentration of hydroxide ions (OH-) in a solution. It is the negative logarithm (base 10) of the hydroxide ion concentration.
In this case, since we have hydrochloric acid (HCl), we need to consider the concentration of hydroxide ions (OH-) produced when HCl dissociates in water.
HCl is a strong acid and completely dissociates, meaning it produces an equal concentration of hydrogen ions (H+) and chloride ions (Cl-) in water. Since there are no hydroxide ions produced, the concentration of hydroxide ions is 0.
Therefore, the pOH of a hydrochloric acid solution is 0, and none of the options provided (A, B, C, D) is the correct answer.

Answer:
Hey mate....
Explanation:
This is ur answer....
They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians), Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

Carbon dioxide, when present in sufficient amounts, will bind with water to form ____________ , which is capable of dissociating into bicarbonate and hydrogen ions.
Answer:
Carbon dioxide, when present in sufficient amounts, will bind with water to form carbonic acid, which is capable of dissociating into bicarbonate and hydrogen ions.
Explanation:
With the help of carbonic anhydrase which further catalyzes the reaction to convert carbonic acid back into carbon dioxide and water. The carbon dioxide is then expelled from the lungs.
how many moles of oxygen are in 20 grams of oxygen
Answer:
0.625
Explanation:
If you are referring the O2, first you need to get the relative mass of it. You can see the O's is around 16. but this is O2,you need to multiple it.
16×2=32
We get the equation n=m/M where m is for gram
20/32=0.625mol

This is a redox reaction but not a combustion reaction.
Redox Reaction
A type of chemical reaction that involves a transfer of electrons or gain of electrons between two-element. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes.
Combustion reaction
It must have two products. CO2 and H2Ooxygen in the reactant is must.

In the malate-aspartate shuttle, _____ is reduced to _____ in the cytosol. oxaloacetate; malate aspartate; malate malate; aspartate malate; oxaloacetate aspartate; oxaloacetate
The malate-aspartate shuttle enables oxidative phosphorylation by allowing electrons to be moved across the inner membrane in the mitochondrion during glycolysis in eukaryotes.
In this malate-aspartate shuttle, oxaloacetate is reduced to malate in the cytosol.
During this biochemical system process, the cytosolic malate dehydrogenase which is the primary enzyme present in this shuttle system catalyzes the reaction of oxaloacetate and NADH to produce malate and NAD in the cytosol.

07-
Na 2+
N 3+
Ca2+
Answer:
Ca(2+)
Explanation:
Sodium (Na) only have one valence electron and will lose it in order to gain a full octet. There will be an unbalance of electrons and protons where there are more protons there electrons. The correct ion formula for sodium is Na (1+).
Nitrogen has 5 valence electrons and will gain three more to gain a full octet. There will be an unbalance where there are more electrons then protons. Nitrogen will form the ion N (3-).
Calcium has two valence electrons and will lose them in order to gain a full octet. There will be an unbalance where there are more protons then electrons. Calcium will form the ion Ca 2+
Therefore, Ca2+ is the ion with the correct charge.

if the column of water in the water barometer rose to a height of 39 feet, what would the atmospheric pressure be in mm hg?
The atmospheric pressure for a column of water barometer that rose to 39 feet is 874 mmHg
From the given information, to determine the atmospheric pressure at which the column of the water barometer rose, we will need to convert the height of the water column to mmHg.
From the dimensional analysis of standard rate conversion, we know that:
1 feet = 12 inches
1 inch = 25.4 mm
1 mmHg = 13.6 mm of water.
∴
[tex]\mathbf{\implies 39 \ feet \ of \ H_2O \times \dfrac{12 \ in ch \ H_2O}{1 \ feet \ H_2O} \times \dfrac{25.4 \ mm \ H_2O}{1 \ inch \ H_2O} \times \dfrac{1 mmHg}{13.6 \ mm \ H_2O}}[/tex]
