According to the concept of solubility and dissociation, aspirin at pH 8 and 10 undergoes dissociation to yield ions.
What are ions?
An ion is defined as an atom or a molecule which has a net electrical charge. There are 2 types of ions :1) cation 2) anion . The cation is the positively charged ion and anion is the negatively charged ion . As they are oppositely charged they attract each resulting in the formation of ionic bond.
Ions consisting of single atom are mono-atomic ions while which consists of two or more ions are called as poly-atomic ions . They are created by chemical interactions . They are very reactive in their gaseous state and rapidly react with oppositely charged ions resulting in neutral molecules.Ions are generated on dissociation.

If the initial temperature of a movable cylinder was 130 degrees Celsius
with a pressure of 1 ATM and an initial volume of 2 Liters, what would
the new volume be if the temperature was lowered to 324 degrees Kelvin
and the pressure was raised to 1.1 ATM?
Answer: The new volume will be 1.5 L
Explanation:
The combined gas equation is,
[tex]\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}[/tex]
where,
[tex]P_1[/tex] = initial pressure of gas = 1 atm
[tex]P_2[/tex] = final pressure of gas = 1.1 atm
[tex]V_1[/tex] = initial volume of gas = 2 L
[tex]V_2[/tex] = final volume of gas = ?
[tex]T_1[/tex] = initial temperature of gas = [tex]130^0C=(130+273)K=403K[/tex]
[tex]T_2[/tex] = final temperature of gas = [tex]324K[/tex]
Now put all the given values in the above equation, we get:
[tex]\frac{1\times 2}{403}=\frac{1.1\times V_2}{324}[/tex]
[tex]V_2=1.5L[/tex]
The new volume will be 1.5 L

How acidic buffer resist change in pH on addition of acid and base.
Answer:
Buffers are solutions that resist changes in pH, upon addition of small amounts of acid or base. The can do this because they contain an acidic component, HA, to neutralize OH- ions, and a basic component, A-, to neutralize H+ ions. Since Ka is a constant, the [H+] will depend directly on the ratio of [HA]/[A-].

Answer:
In algae or any other photosynthetic organism, there is the internalization of carbon dioxide gas in the reaction with water in the presence of sunlight to produce sugar molecules and oxygen gas in the atmosphere. So, photosynthesis is the process that releases or produces oxygen gas.
In cellular respiration (aerobic) the product of photosynthesis, glucose molecules, and oxygen react to produce the energy and releases carbon dioxide and water as byproducts.
The given question is incomplete, it lacks the diagrams (choices), however, the correct choices are attached as image:
The diagrams accurately represent the use of gases in both cellular respiration and photosynthesis is - diagram d. (check image)
CELLULAR RESPIRATION:
is the process in which living organisms obtain energy (ATP) by breaking down food molecules in their cells. It combines glucose and oxygen to produce carbon dioxide (CO2) and water (H2O) as follows: C6H12O6 + 6O2 = 6CO2 + 6H2OPHOTOSYNTHESIS
is the process in which green plants manufacture their own food using energy from sunlight. It combines carbon dioxide (CO2) and water (H2O) to produce glucose and oxygen (O2) as follows:6CO2 + 6H2O = C6H12O6 + 6O2

A chemical reaction produces 138 mol of HBr gas. What volume will that gas occupy at STP?
3.09E3 L
3.09E4L
22.4L
3.25E2L
The chemical reaction at STP results in a volume of HBr gas that is roughly 3.09E3 L.
An example of a chemical reactionIn a chemical reaction, reactants undergo a chemical reaction and transform into products through a chemical process. For instance, when humans breathe in oxygen, it combines with glucose to create carbon dioxide, water, and energy.
The temperature is 273.15 K and the pressure is 1 atm at STP (standard temperature and pressure).
The ideal gas law can be rearranged to account for V:
V = (nRT) / P
Substituting the values we are aware of:
n = 138 mol
R = 0.0821 L·atm/(mol·K)
T = 273.15 K
P = 1 atm
V = (138 mol * 0.0821 L·atm/(mol·K) * 273.15 K) / 1 atm
V = 3,092.1 L

PLEASE MARK AS BRAINLIESTAn object has a mass of 15.2 g and a volume of 8.9 mL.
What is the density of the object?
Answer:
recordando también que ** 1mL = 1cm ^ 3 **
(como ** 1 dm ^ 3 = 1 L **)
You are given a sample of an unknown solution and are tasked with determining the density. The solution is miscible with water, so you cannot use a float test. To complete this task, you begin by obtaining a clean dry beaker and measure its mass on a balance (120.3621 g). You then use a pipet to transfer the liquid into the beaker. The initial reading on your pipet is 4.126 mL and after you have dispensed the liquid the pipet reads 6.518 mL. You then obtain the mass of the beaker with the liquid inside (123.0194 g).
_____g/mL
Answer: 1.11 g/mL
Explanation:
Density = mass/vol
mass 123.0194-120.3621g = 2.6574
vol 6.518-4.126 ml = 2.392
Scientists are unable to research the organs, tissues, and cells of early organisms as these parts are rarely fossilized. Which is one reason for the lack of these fossilized parts?
Answer:
A. These parts quickly decompose.
Explanation: This is because organs are made of tissues that decompose more quickly than bone. Animals mainly eat the organs and tissues of another, not the bones. This results in quick destruction of these parts that are left behind.
Have a blessed day/night! Please mark brainliest if correct! <3
The reason for the lack of these fossilized parts is that these part quickly decompose. Hence option A is correct.
What is fossilization?Fossilization is defined as the mechanisms that are physical, chemical, and biological that result in the long-term preservation of plant and animal remnants. Fossilization is a negative representation of the creature preserved in the substrate as a fossil. Any preserved remains, impression, or trace of a once-living thing from a previous geological age is referred to as a fossil.
Decomposition is defined as the method through which decomposing organic matter yields more basic organic or inorganic elements . The process of recycling nutrients that have been consumed by an organism to create its body begins with decomposition. It is the process through which the dead tissues disintegrate and change into more basic organic forms.
Thus, the reason for the lack of these fossilized parts is that these part quickly decompose. Hence option A is correct.
