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

first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge.
Explanation:
things which are matter but not substance
Answer:
Vacuum
Explanation:
It may be bounded by a volume. Energy: Light, heat, kinetic and potential energy, and sound are non-matter because they are massless. Objects that have mass and are matter may emit energy.

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. This system enables oxidative phosphorylation in eukaryotes.Learn more: https://brainly.com/question/17216910

If a solid object is taken from Earth far into space, which of the following measurements of the object will change the most?
A. density
B. mass
C. volume
D. weight
Answer:-option D. weight
Explanation:-Because the gravity of the planet/object changes, the weight of the object changes when you move it away from the earth or place it on another planet.
However, the mass of the object remains the same regardless of whether it is on Earth or outer space.

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.

Why are herbivores in level two of a food
web?
Worth 20 points :)
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.
