B. It would increase.
C. It would stay the same.
D. You cannot tell from this graph.

The number of atoms of any element in the given chemical formula is the number that is written on the foot of the symbol of that element. Therefore, chlorine has the strongest attraction for electrons in a chemical bond.

Atom is the smallest particle of any matter. Atom combines to form element and element combine to form molecule or compound.

Atom consists of electron, proton and neutron. The total mass of atom is inside the nucleus. Inside the nucleus proton and neutron is there. So calculate mass of an atom, total mass of all protons is added to the total mass of neutron. Electrons revolve around the nucleus.

Electronegative element have greatest strongest attraction for electrons due to high effective nuclear charge. Among the given molecules, chlorine is the most electronegative element. Chlorine has the strongest attraction for electrons in a chemical bond.

Therefore, chlorine has the strongest attraction for electrons in a chemical bond.

Answer:

0.370 M

Explanation:

Step 1: Given data

Molar concentration of the sodium carbonate solution: 0.185 M

Step 2: Write the balanced dissociation equation

Sodium carbonate is a strong electrolyte that dissociates according to the following equation.

Na₂CO₃(aq) ⇒ 2 Na⁺(aq) + CO₃²⁻(aq)

Step 3: Calculate the molar concentration of sodium ions

The molar ratio of Na₂CO₃ to Na⁺ is 1:2.

0.185 mol Na₂CO₃/L × 2 mol Na⁺/1 mol Na₂CO₃ = 0.370 mol Na⁺/L

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]

According to the concept of solubility and dissociation, aspirin at pH 8 and 10 undergoes dissociation to yield 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.

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 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⁻.

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⁻.

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.

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.
