Answer:

<em>¹⁴₇N + ⁴₂He → ¹⁷ ₈O + ¹₁p</em>


Explanation:


¹⁴₇N represents the isotope of nitrogen-14, where the superscript 14 to the left of the chemical symbol of the element  is the mass number (number of protons and neutrons) and the subscripst 7 is the atomic number (number of protons).


α is used to represent alpha particles. Alpha particles are nucleus of helium, ⁴₂He: mass number 4, atomic number 2,

The expression ¹⁴₇N + α represents a nuclear reaction: the nucleus of the isotope of nitrogen-14 (¹⁴₇N) is hit by α-particles ( ⁴₂He).


As result, the nucleus of ¹⁴₇N absorbs 1 proton, increasing its atomic number and mass number in 1, becoming ¹⁷ ₈O. In this process, also one proton is produced.


The total reaction is represented by ¹⁴₇N + ⁴₂He → ¹⁷ ₈O + ¹₁p, where you can verify the mass balance:


Mass numbers: 14 + 4 = 17 + 1 = 18.

Number of protons: 7 + 2 = 8 + 1 = 9.

Core reactions that occur:

¹⁴₇N + ⁴₂He → ¹⁷₈O + ¹₁H

<h3>Further explanation</h3>

Fusion and fission reactions are reactions involving atomic nucleus reactions

Fission reaction is a nucleation division reaction by firing a particle usually neutron so that it gets smaller particles of atomic nuclei.

Example:

Uranium nuclei division reaction

²³⁵₉₂U + ¹₀n -> ⁸⁹₃₆Kr + ¹⁴⁴₅₆Ba + 3¹₀n

In this reaction, Uranium splits into Kr and Ba isotopes and releases energy and gamma radiation

Energy is generated based on the isotope mass from the beginning of the reaction and after division

A fusion reaction is a combining reaction of 2 atomic nuclei. Usually what is often used is a reaction between the hydrogen isotope that will form Helium

³₁Ti + ²₁D  -> ⁴₂He + ¹₀n

Isotopes of Hydrogen Tritium and Deuterium form Helium

At the core, reaction applies the law of eternity

  • 1. energy

the energy before and after the reaction is the same

  • 2. atomic number

the number of atomic numbers before and after the same

  • 3. mass number

the number of mass numbers before and after the same

Particles that play a role in core reactions include

alpha α particles ₂He⁴

beta β ₋₁e⁰ particles

gamma particles γ

positron particles ₁e⁰

In general, the core reaction equation can be written:

X = target core

a = particle fired

Y = new core

b = the particle produced

Q = heat energy

or can be written simply

X (a, b) Y

In the ¹⁴₇N  atomic nucleus, it is shot with alpha ⁴₂He rays which produce isotopes of Oxygen and ¹₁H protons.

¹⁴₇N + ⁴₂He → ¹⁷₈O + ¹₁H

This reaction can be written down

¹⁴₇N (α, H) ¹⁷₈O

The sum of the atomic numbers and mass numbers before and after are the same

When 1.95 g of co(no3)2 is dissolved in 0.350 l of 0.220 m koh, what are [ co2+], [ co(oh)42−], and [ oh−] if kf of co(oh)42− =
Airida [17]
Mass of Co(NO₃)₂ = 1.95 g
V KOH = 0.350 L
[KOH] = 0.220 M
Kf = 5.0 x 10⁹
molar mass of Co(NO₃)₂ = 182.943 g/mol
so [Co(NO₃)₂] = 1.95 / (0.350 * 182.943) = 0.03045 M
[Co²⁺] = 0.03045 M
[OH⁻] = 0.22 M
chemical reaction:
             Co²⁺(aq) + 4 OH⁻    ⇄      Co(OH)₄²⁻
I (M)      0.03045      0.22                   0
C (M)   - 0.03045   - 4 (0.03045)      0.03045
E (M)       - x         0.22 - 4(0.03045)   0.03045
                              = 0.0982
Kf  = [Co(OH)₄²⁻] / [Co⁺²][OH⁻]⁴
5.0 x 10⁹ = (0.03045) / x (0.0982)⁴
x = 6.5489 x 10⁻⁸
at equilibrium:
[Co²⁺] = 6.54 x 10⁻⁸
[OH⁻] = 0.0982 M
[Co(OH)₄²⁻] = 0.03045 M

<h3><u>Full Question:</u></h3>

The following compound has been found effective in treating pain and inflammation (J. Med. Chem. 2007, 4222). Which sequence correctly ranks each carbonyl group in order of increasing reactivity toward nucleophilic addition?

A) 1 < 2 < 3

B) 2 < 3 < 1

C) 3 < 1 < 2

D) 1 < 3 < 2

<h3><u>Answer: </u></h3>

The rate of nucleophilic attack of carbonyl compounds is 2<3 <1.

Option B

<h3><u>Explanation. </u></h3>

Nucleophilic attack is explained as the attack of an electron rich radical to a carbonyl compound like aldehyde or a ketone. A nucleophile has a high electron density, so it searches for a electropositive atom where it can donate a portion of its electron density and become stable.

A carbonyl compound is a sp^2 hybridized carbon atom with a double bonded oxygen atom in it. The oxygen atom pulls a huge portion of electron density from carbon being very electropositive.

In a ketone, there are two factors that make it less likely to undergo a nucleophilic attack than aldehyde. Firstly, the steric hindrance of two carbon groups being attached with the carbonyl carbon makes it harder for the nucleophile to approach. Secondly, the electron push by the carbon groups attached makes the carbonyl carbon a bit less electropositive than the aldehyde one. So aldehydes are more reactive towards a nucleophilic addition reaction.

Given the chemical reaction: Hg2+(aq) + Cu(s) + Hg(s) + Cu2+(aq)
Pavel [41]

Answer: When the reaction reaches equilibrium, the cell potential will be 0.00 V

Explanation:

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.

The equilibrium is dynamic in nature and the reactions are continuous in nature. Rate of forward reaction is equal to the rate of backward reaction.

The standard emf of a cell is related to Gibbs free energy by following relation:

\Delta G=-nFE^0

The Gibbs free energy is related to equilibrium constant by following relation:

\Delta G=-2.303RTlog K

For equilibrium \Delta G=0

Thus 0=-nFE^0

E^0=0

Thus When the reaction reaches equilibrium, the cell potential will be 0.00 V
