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.

A chemist prepares a solution of silver(I) perchlorate by measuring out of silver(I) perchlorate into a volumetric flask and filling the flask to the mark with water. Calculate the concentration in of the chemist's silver(I) perchlorate solution. Be sure your answer has the correct number of significant digits.
The question is incomplete, the complete question is;
A chemist prepares a solution of silver (I) perchlorate (AgCIO4) by measuring out 134.g of silver (I) perchlorate into a 50.ml volumetric flask and filling the flask to the mark with water. calculate the concentration in mol/L of the silver (I) perchlorate solution. Round your answer to 2 significant digits.
Answer:
13 mol/L
Explanation:
We must first obtain the number of moles of silver I perchlorate involved
Molar mass of silver I perchlorate = 207.32 g/mol
Number of moles of silver I perchlorate = 134g/207.32 g/mol = 0.646 moles
Recall that;
n =CV
C= concentration
V= volume
n = number of moles
C = n/V
C = 0.646 moles * 1000/50
C = 13 mol/L
A balloon with a volume of 0.5L at 293K is cooled to 20K. What is the balloon's new
volume?
Answer:
0.03 L
Explanation:
Step 1: Given data
Initial volume of the balloon (V₁): 0.5 LInitial temperature of the balloon (T₁): 293 KFinal volume of the balloon (V₂): ?Final temperature of the balloon (T₂): 20 KStep 2: Calculate the final volume of the balloon
The balloon is filled with air. If we assume it behaves as an ideal gas, we can calculate the final volume of the balloon using Charles' law.
V₁/T₁ = V₂/T₂
V₂ = V₁ × T₂/T₁
V₂ = 0.5 L × 20 K/293 K = 0.03 L
Write the formula of the conjugate base of the Brønsted-Lowry acid, HIO3
Answer:
Explanation:
A conjugate base of HIO3 is IO3– ion
The chemical formula of the conjugate base of the Bronsted Lowry acid HIO₃ can be represented as IO₃⁻.
What is Bronsted - Lowry acid and bases?According to Bronsted - Lowry theory, acid is a substance that donates a proton or H⁺ ion and forms its conjugate base while the base is a substance that accepts a proton or H⁺ ion and forms its conjugate acid.
Bronsted-Lowry acid donates a proton to the other compound and forms a conjugate base.
Acid ⇄ Conjugate base + Proton
If a conjugate base accepts a proton back then acid reforms.
The Bronsted-Lowry base is a substance that accepts a proton from other compounds.
Base + Proton ⇄ Conjugate acid
If a conjugated acid donates its proton then the base reforms.
The conjugate base of the Bronsted-Lowry acid HIO₃ is:
HIO₃ ⇄ H⁺ + IO₃⁻
Therefore, the conjugate base of the Bronsted-Lowry acid HIO₃ is IO₃⁻.

An ore sample is found to contain 10.500000 g of cobalt and 87.3 g waste rock (gangue). What is the
percent by mass of cobalt in the ore?
Answer:
[tex]\% Co=10.7\%[/tex]
Explanation:
Hello!
In this case, since this is a mixture composed by cobalt and waste rock, we can compute the percent by mass of cobalt as shown below:
[tex]\% Co=\frac{m_{Co}}{m_{Co}+m_{waste}} *100\%\\\\[/tex]
Thus, we plug in to obtain:
[tex]\% Co=\frac{10.500000g}{10.500000g+87.3} *100\%\\\\\% Co=10.7\%[/tex]

Pleaseeeeeee helppppppp
Answer:
A) Ionic compounds containing variable metals should have Roman numerals
Explanation:
The correct option is;
A) Ionic compounds containing variable metals should have Roman numerals
This is because these variable metals have variable oxidation states and charges. Hence, to be able to distinguish between compounds containing the same element but different charges, the roman numerals is used. For example;

Which of the following best describes the outcome of the cell division process meoisis?
Select one:
A. Meosis does not occur in reproductive cells.
B. The cells produced at the end of meiosis are genetically identical to the parent cell.
C. The cells produced at the end of meiosis contain half the number of chromosomes as the parent cell.
D. Cells only divide once during meiosis.
Answer:
Explanation: The answer is B. Because meiosis process produce genetically different, haploid cells. Also, meiosis basically happen to produce gametes. Gametes is haploid. So, the answer is B
Meiosis is a method for cell division taking place in some organisms. In meiosis the cell the cells produced at the end of meiosis contain half the number of chromosomes as the parent cell. Hence, option C is correct.
What is meiosis?meiosis is biological process by which the cell undergo division to produce genetically identical daughter cells. Other methods of cell divisions include mitosis, binary division, budding etc.
The first stage of meiosis includes pairing homologous chromosomes and they segregate to opposite ends of the meiotic spindle.This phase is known as reduction division where, the number of chromosome reduces to half.
This differentiated chromatids separates out in the second phase and yielding the haploid cells. Hence, in meiosis, the cells produced at the end of meiosis contain half the number of chromosomes as the parent cell.

Where is the main asteroid belt in the solar system?
Answer:
It's between Jupiter and Mars.Draw the structure of the product formed in the reaction of an epoxide with ethoxide ion. If more than one stereochemical product is possible, draw only one isomer.
Answer:
See explanation and image attached
Explanation:
The most common reaction of epoxide rings is the ring opening reaction. This ring opening reaction serves to relieve the stress in the ring.
Now, The first step in the acid catalysed epoxide ring opening reaction is the protonation of the epoxide.
This is now followed by the attack of the nucleophile. Subsequent deprotonation regenerates the acid catalyst and yields the product.
The structure of the product formed in the reaction of an epoxide with ethoxide ion is attached below as we get 2 substituted alcohol product.
What are epoxides?Epoxides are comes under the category of ether, which are the three membered ring structure.
Due to its ring structure, strain or stress is present in the three membered ring which makes it available to react easily with nucleophile. Ethoxide ion acts as a nucleophile in this reaction which attacks on the electrophilic carbon of the epoxide and resulting into the break up of bond and opening of ring.
As a result of this reaction we get the 2 substituted alcohol as attached in the image.
Hence structure of the product is attached below.
