which of the following is the conjugate acid of CIO-​

Answer:

+3

12 electrons and 15 protons.

Explanation:

The element having 15 electrons and 15 protons have atomic number 15. We know that when an atom lose or gain the electron ions are formed.

Anion formation:

Anion is formed when electron is accept by an atom.

X + e⁻ → X⁻

Cation formation:

Cation is formed when electron lose be an atom.

X → X⁺ + e⁻

The given atom loses 3 electrons thus oxidation number will be +3 and cation is formed.

X → X³⁺ + 3e⁻

Now element X have 15 protons and 12 electrons.

Answer: the density of the rock

55.91g/ml

Explanation:

The density of the rock after it had being placed in the cylinder of water so the calculation should look like this:

Volume of water substract the mass of the rock:

And that is 142.5 ml - 86.59g =

Answer 55.91 g/ml

So the density of the rock is 55.91g/ml

Explanation:

What occurred then is as a result of nuclear fission. This occurs as the Uranium-235 split into two smaller nuclei while releasing high energy neutrons. These neutrons bombard existing U-235 in the atmosphere and this reaction continue in a spontaneous manner until a chain reaction is formed of U-235, whose fall out fills the environment. This process was what led to people been exposed to high intensity radiation in the days and months after the atomic bomb was dropped.

0.010g of C-14 would be later after 50,000 years

Explanation:

The kinetics of radioactive decay follows the equation:

Ln (N / N₀) = -kt

Where N could be taken as mass after time t,

N₀ initial mass = 4.30g;

k is rate constant = ln 2 / t(1/2)

= ln 2 / 5730years = 1.2097x10⁻⁴ years ⁻¹

Replacing:

Ln (N / 4.30g) = -1.2097x10⁻⁴ years ⁻¹ * 50000 years

N / 4.30 = 2.36x10⁻³

Answer:

14.52%

Explanation:

The percentage by mass (WW%) is calculated by using the formula:

Mass of solute/mass of solution ×

100

The solute (Al) is 22.5g while the solvent (Al2O3) is 155g

Hence, percent by mass is:

22.5/155 × 100

= 0.1452 × 100

= 14.52%

Answer:  the aspirin also contains a buffering agent—usually MgO—that regulates the acidity of the aspirin to minimize its acidic side effects.

Explanation:

Because the acid residences of aspirin may be complex, many aspirin manufacturers provide a "buffered aspirin" form of the drug. In these cases, the aspirin additionally includes a buffering agent-normally MgO-that regulates the acidity of the aspirin to minimize its acidic aspect consequences.

Buffering agents are utilized in tablet formulations to grow the dissolution and absorption of vulnerable acid pills together with salicylic acid, aspirin, and p-aminosalicylic acid as well as to lower gastric infection of lively ingredients.

So-called "buffered aspirin" isn't surely a buffer, because it does no longer face up to acids and bases. it's miles sincerely aspirin mixed with a primary compound, consisting of magnesium carbonate or aluminum hydroxide, which neutralizes some belly acid.

Answer:

P(Kr) = 1.2 atm

Explanation:

According to Dalton law of partial pressure,

The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.

Mathematical expression:

P(total) = P₁ + P₂ + P₃+ ............+Pₙ

Now we will solve this  problem by using this law

Total pressure = 1.60 atm

Partial pressure of neon = 0.40 atm

Partial pressure of krypton = ?

Solution:

P(total) = P(Ne)+ P(Kr)

1.60 atm = 0.40 atm +P(Kr)

P(Kr) = 1.60 atm -  0.40 atm

P(Kr) = 1.2 atm

The partial pressure of Krypton in the mixture has been 1.2 atm.

Partial pressure can be defined as the pressure exerted by a single gas in the solution.

According to Dalton’s law of partial pressure, the total pressure of the gas has been the summation of the partial pressure of each gas present in the mixture.

Total pressure = Partial pressure of A + Partial pressure of B + Partial pressure of C……

The given mixture has been consisted of neon and krypton. The total pressure of the mixture has been:

Total pressure = Partial pressure of Ne + Partial pressure of Kr

The total pressure = 1.60 atm.

The partial pressure of Ne = 0.40 atm.

Substituting the values:

1.60 atm = 0.40 atm + Partial pressure of Kr

Partial pressure of Kr = 1.60 - 0.40 atm

Partial pressure of Kr = 1.2 atm.

The partial pressure of Krypton in the mixture has been 1.2 atm.

Explanation:

Ag+

From the given reaction, it is clear that, Ag is gaining electrons from the base NH₃ . Hence, according to Lewis concept of acids and bases, Ag⁺ is the Lewis acid.

There are various concepts to define acids and bases. Among which the first was Arrhenius theory. This theory states that, acids are substances which can furnish H+ in solution and bases are substances giving OH- in solution.

Then Bronsted- Lowry concept states acids as proton donor and bases as proton acceptors. The most applicable theory for acids and bases is Lewis concept.

According to Lewis theory of acids and bases, acids are electrons acceptors and bases are electron donors.

The given reaction is written as:

[tex]\rm Ag^{+} + 2NH_{3} \rightarrow Ag(NH_{3})_{2}[/tex]

Here, Ag⁺ is the Lewis acid which accepts an electron from the Lewis base NH₃.
