H₂SO₃ is weaker acid than H₂SO₄.

The bonding power of an acid is typically influenced by the size of the "SO₄" atom; the smaller the "SO₄" atom, the stronger the H-A bond. The atoms get larger and the bonds get weaker as you proceed down a row in the Periodic Table, strengthening the acids.

<h3>Describe acid.</h3>

The term "acid" refers to any molecule or ion that can donate a proton (a Brnsted-Lowry acid) or establish a covalent bond with an electron pair (a Lewis acid). The first class of acids is the proton donors, also known as Brnsted-Lowry acids.

Its chemical name is lysergic acid diethylamide, or LSD as it is more often known. Because it has a potent hallucinogenic impact, using it could alter how you see the world and its objects. The effects of LSD are referred to as tripping.

The term "acid" is frequently used to denote aqueous solutions of acids with a pH lower than 8, even though the technical meaning of the term only pertains to the solute.

Given the information below, which is more favorable energetically, the oxidation of succinate to fumarate by NAD+ or by FAD? Fu

sasho [114]

Answer:

Oxidation by FAD

Explanation:

1. Oxidation by NAD⁺

Succinate ⇌ Fumarate + <u>2H⁺ + 2e⁻</u>; E°´ = -0.031 V

Succinate + NAD⁺ ⇌ Fumarate + NADH + H⁺; E°' = -0.351 V

2. Oxidation by FAD

Succinate ⇌ Fumarate + 2H⁺ + 2e⁻; E°´ = -0.031 V

Succinate + FADH₂ ⇌ Fumarate + FAD; E°' = -0.250 V

Neither reaction is energetically favourable, but FAD has a more positive half-cell potential.

FAD is the stronger oxidizing agent.

The oxidation by FAD has a more positive cell potential, so it is more favourable energetically.

Describe the hybrid orbitals used by the central atom(s) and the type(s) of bonds formed in:

BaLLatris [955]

The valence orbitals of a central atom surrounded by three regions of electron density consist of a set of three sp2 hybrid orbitals and one unhybridized p orbital.

<h3> Is Nitrosyl fluoride polar or non polar?</h3>

The affinity for electrons between the two atoms will keep them together, resulting in the sharing of electron density. In the case of Nitryl fluoride, The N-F bond is polar, acting as a dipole with a partial positive charge on the nitrogen atom and a partial negative charge on the fluorine atom, respectively.

<h3>Is Nitrosyl fluoride a gas?</h3>

Nitryl fluoride, NO2F, is a colourless gas and strong oxidizing agent, which is used as a fluorinating agent and has been proposed as an oxidiser in rocket propellants (though never flown).

2. A satellite can generate a maximum force of 550 N using its rockets. The

Gemiola [76]

The satellite's rockets fire in 18.54 s

<h3>Further explanation</h3>

Given

F- Force = 550 N

I - impulse = 10,200 kg m/s

Required

Fire time

Solution

Impulse is defined is the product of the force with the time interval when the force is acting on the object.

Can be formulated :

I = F. Δt

Δt = I : F

Input the value :

$\tt \Delta t=\dfrac{I}{F}\\\\\Delta t=\dfrac{10200}{550}\\\\\Delta t=\boxed{\bold{18.54~s}}$
