What is the compound N₂O3 called?

Glutamic amino acid is the non-essential amino acid and an excitatory neurotransmitter. When Glu is found in the core then the pKa of the side chain group increases.

pKa is the acid strength or the estimate that shows whether the solution is weak or strong acid. pKa less than zero is a strong acid and portrays the bonding of the proton by the acids.

In the Glu amino acid, the value of the pKa of the side chain functional groups increases as the amino acid is found in the interior of the water-soluble folded protein structure.

Therefore, the pKa of the side-chain increases.

Answer:

299.60 g

Explanation:

Use the formula q = mCΔT (q= heat, m= mass, c = specific heat for that specific substance, ΔT is change in temperature Final Temp - Initial Temp)

Released heat means it has negative sign.

q = mCΔT

-2744 = (mass) (0.129) (19-90)

mass= 299.60 g

After acid was added to the solution and the hydronium ion concentration becomes 100 times greater, the pH of the new solution is 5.

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

It is expressed as;

pH = -log[ H⁺]

Given that;

pH = -log[ H⁺]

H⁺ = 10^( -pH )

H⁺ = 10^( -7 )

H⁺ = 10⁻⁷

When acid is added to the solution, the hydronium ion concentration becomes 100 times greater.

H⁺ = 10⁻⁷ × 100

H⁺ = 10⁻⁵

pH of the new solution will be;

pH = -log[ H⁺ ]

pH = -log[ 10⁻⁵ ]

pH = 5

Therefore, after acid was added to the solution and the hydronium ion concentration becomes 100 times greater, the pH of the new solution is 5.

Cations are ions that has a positive charge on it, and since it's a positive charge, it means that the ion has more protons than the number of electrons.

On the same contray, Anions are negatively charged particles having more electrons than protons in it, and hence bearing a negative charge.

property : non - alike ions attract each other by electrostatic force.

Answer:

Cations are positively-charged ions.

Anions are negatively-charged ions.

The best explanation would be that the temperature of the gas has dropped before measuring the pressure.

According to pressure law, the pressure of a gas is directly proportional to its temperature, provided the volume of the gas remains constant.

Thus, since the initial pressure of the gas was calculated to be 7.5 atm, the temperature of the gas must have dropped in order for the measured pressure to be 7.1 atm.

Explanation:

The spectrum of the first compound will have only one signal, but the spectrum of the second compound will have two signals.

A compound is a substance formed by combining two or more different chemical elements in such a way that the atoms of the individual elements are linked together by chemical bonds that are difficult to break in chemistry.

Hence it is right to state that the spectrum of the first compound will have only one signal, but the spectrum of the second compound will have two signals.

Explanation:

The maximum mass of NH₃ that can be formed when 36.52 g of N₂ reacts with 10.62 g of H₂ is 44.35 g

N₂ + 3H₂ —> 2NH₃

Molar mass of N₂ = 14 × 2 = 28 g/mol

Mass of N₂ from the balanced equation = 1 × 28 = 28 g

Molar mass of H₂ = 2 × 1 = 2 g/mol

Mass of H₂ from the balanced equation = 3 × 2 = 6 g

Molar mass of NH₃ = 14 + (3×1) = 17 g/mol

Mass of NH₃ from the balanced equation = 2 × 17 = 34 g

SUMMARY

From the balanced equation above,

28 g of N₂ reacted with 6 g of H₂ to produce 34 g of NH₃

From the balanced equation above,

28 g of N₂ reacted with 6 g of H₂

Therefore,

36.52 g of N₂ will react with = (36.52 × 6) / 28 = 7.83 g of H₂

From the above calculation, we can see that only 7.83 g out of 10.62 g of H₂ are required to react completely with 36.52 g of N₂.

Therefore, N₂ is the limiting reactant

From the balanced equation above,

28 g of N₂ reacted to produce 34 g of NH₃

Therefore,

36.52 g of N₂ will react to produce = (36.52 × 34) / 28 = 44.35 g of NH₃

Thus, the maximum mass of NH₃ obtained from the reaction is 44.35 g

Considering Gay-Lussac's law, a gas exerts a pressure of 4.00 atm at 1,092 K.

Gay-Lussac's law states that the pressure of a gas is directly proportional to its temperature: when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, gas pressure decreases.

Gay-Lussac's law can be expressed mathematically as follows:

[tex]\frac{P}{T}=k[/tex]

where P= pressure, T= temperature, k= Constant

This law states that the ratio of pressure to temperature is constant.

Studying an initial state 1 and a final state 2, it is fulfilled:

[tex]\frac{P1}{T1}=\frac{P2}{T2}[/tex]

In this case, you know:

Replacing in Gay-Lussac's law:

[tex]\frac{1 atm}{273 K}=\frac{4 atm}{T2}[/tex]

Solving:

[tex]T2\frac{1 atm}{273 K}=4 atm[/tex]

[tex]T2=\frac{4 atm}{\frac{1 atm}{273 K}}[/tex]

T2= 1,092 K

Finally, a gas exerts a pressure of 4.00 atm at 1,092 K.

Answer:

Partial pressure of O2 = 4.93 atm

Explanation:

PV = n RT        R = .082057 L-atm/mol-K

n = 6.3 + 8.15 = 14.45 moles

348 C = 621.15 K

P (65.1) = 14.45 ( .082057)(621.15) = 11.31 atm

Now the fraction of pressure from Oxygen is

   6.3 / (6.3+8.15)  * 11.31 = 4.93 atm
