The equilibrium constant kp for the given reaction is 1.89 x 10^(-51).

The equilibrium constant kp for the given reaction can be calculated using the relationship between kp and kc, which is:

kp = kc(RT)^(Δn)

Where R is the gas constant, T is the temperature in Kelvin, and Δn is the change in the number of moles of gas in the reaction.

For the given reaction, Δn = (1 + 3/2) - 1 = 1/2

The temperature in Kelvin is T = 1100 + 273 = 1373 K

Plugging in the values, we get:

kp = (1.47 X 10^{-52})(8.314)(1373)^{1/2}

kp = 1.89 x 10^(-51)

Therefore, the answer is kp = 1.89 x 10^(-51).

The instability of the fulminate ion is due to its highly polarized nature, which makes it prone to explosive reactions.

A resonance structure is a collection of two or more Lewis Structures that describe the electronic bonding of a single polyatomic species, including fractional bonds and fractional charges.

The cyanate ion (NCO⁻) and the fulminate ion (CNO⁻) have the same three atoms - nitrogen (N), carbon (C), and oxygen (O) - but different arrangements of those atoms, which result in vastly different chemical and physical properties.

The cyanate ion is a stable ion that can form salts and is commonly found in inorganic and organic compounds. Its resonance structures are:

      O=C-N⁻ <-> O⁻-C=N

In the first structure, the double bond is between carbon and oxygen, while in the second structure, the double bond is between nitrogen and carbon. The resonance hybrid of the cyanate ion results from the combination of these two structures, which indicates the presence of partial double bond character in both the C-O and C-N bonds.

On the other hand, the fulminate ion is an unstable ion that can form highly explosive compounds. Its resonance structures are:

     C=N-O⁻ <-> C⁺=N-O⁻

In the first structure, the double bond is between nitrogen and oxygen, while in the second structure, the double bond is between carbon and nitrogen. The resonance hybrid of the fulminate ion results from the combination of these two structures, which indicates the presence of partial double bond character in both the N-O and C-N bonds.

The given solution has a [H₃O⁺] of 6.7 x 10⁻⁸. This value indicates the concentration of hydronium ions present in the solution. The solution is basic. The correct option is B.

When the concentration of hydronium ions in a solution is less than 1 x 10⁻⁷ M, the solution is considered to be neutral. However, in this case, the concentration of hydronium ions is greater than 1 x 10⁻⁷ M, which means that the solution is not neutral.

Since the [H₃O⁺] concentration is less than 1 x 10⁻⁷ M, the solution cannot be considered to be acidic. An acidic solution would have a higher concentration of hydronium ions than a neutral solution, with a [H3O+] greater than 1 x 10^-7 M.

Therefore, the only option left is that the solution is basic. A basic solution has a lower concentration of hydronium ions than a neutral solution, with a [H₃O⁺] less than 1 x 10⁻⁷ M. In this case, the solution has a very low concentration of hydronium ions, which means that it is basic.

To summarize, a solution with [H₃O⁺] of 6.7 x 10⁻⁸ is basic, since its concentration of hydronium ions is lower than the concentration of hydronium ions in a neutral solution, and much lower than the concentration of hydronium ions in an acidic solution. The correct option is B.

Answer:

370 cm^3

Explanation:

Here, Density= Mass / Volume

=1.00/370

=370 cm^3.

The density of the metal is approximately 2.70 kg/dm³.

Density (ρ) is calculated by dividing the mass (m) of an object by its volume (V): ρ = m/V.

Given:

Mass (m) = 1.00 kg

Volume (V) = 370 cm³ = 0.370 dm³

Density (ρ) = 1.00 kg / 0.370 dm³ ≈ 2.70 kg/dm³

The density of the metal is approximately 2.70 kg/dm³.

Density is a measure of how much mass is contained within a given volume. In this case, a metal with a mass of 1.00 kg occupies a volume of 370 cm³.

By dividing the mass by the volume, the density is calculated. The resulting value of 2.70 kg/dm³ indicates that for every cubic decimeter (dm³) of volume, the metal has a mass of 2.70 kg.

Litmus is an example of an indicator, a substance that changes color depending on its pH (pH is a measure of the concentration of protons, or H+ ions). In the Titration Gizmo™, you will use indicators to show how acids are neutralized by bases, and vice versa.

To begin, check that 1.00 M NaOH is selected for the Burette, Mystery HBr is selected for the Flask, and Bromthymol blue is selected for the Indicator.

Calculate: Concentration is measured by molarity (M), or moles per liter. Brackets are also used to symbolize molarity. For example, if 0.6 moles of HNO3 are dissolved in a liter of water, you would say [HNO3] = 0.6 M.

Because HNO3 is a strong acid, it dissociates almost completely in water. That means the concentration of H+ is very nearly equal to that of HNO3.What is [H+] if [HNO3] is 0.01 M? 0.01 M

The pH of a solution is equal to the negative log of H+ concentration: pH = –log[H+]

Describe: The equation for the reaction of nitric acid (HNO3) and sodium hydroxide (NaOH) is shown on the bottom right of the Gizmo.

Measure: A titration can be used to determine the concentration of an acid or base by measuring the amount of a solution with a known concentration, called the titrant, which reacts completely with a solution of unknown concentration, called the analyte. The point at which this occurs is called the equivalence point.

Explain: A titration curve is a graph of pH vs. volume of titrant. The graph at right shows a typical titration curve for the titration of a strong acid by a strong base. (A strong base is one that has relatively high dissociation in water.)

According to theBrønsted-Lowry definition, an acid is a substance that is capable of donating a proton to another substance. A base is a substance that accepts protons. When an acid and a base are combined, the acid is neutralized as the base accepts the protons produced by the acid.One way to determine if a solution is acidic or basic is to use litmus paper, as shown above. There are two types of litmus papers: red and blue.How does litmus paper indicate an acid? Both strips turn red.
