I believe an atom. may be wrong, science is not my strong suit
An induced current is a conducting loop that is exposed to a changing magnetic field. And it is knows as induced current
The effusion rate of H2 molecules is 4.342 times that of an unknown gas. Determine the molar mass of the unknown gas. You can write the formula for Graham's law of diffusion or effusion of gases as: rate 1 / rate 2 = √ (mass 2 / mass 1) , where: rate 1 and rate 2 - Rates of effusion or diffusion of Gas 1 and 2, respectively, measured moles per unit time
<h3>What is
H2 molecules?</h3>
The chemical element hydrogen is represented by the letter H and atomic number 1. The lightest element is hydrogen. Under normal circumstances, hydrogen is a gas made up of diatomic molecules with the formula H2. It is non-toxic, tasteless, colorless, odorless, and extremely flammable. In the cosmos, hydrogen is the most prevalent chemical, making up around 75% of all ordinary matter. [note 1] Plasma hydrogen makes up the majority of stars like the Sun. On Earth, hydrogen mostly takes the form of molecules like water and organic substances. Each atom of hydrogen's most prevalent isotope, 1H, has one proton, one electron, and no neutrons.

This problem is providing some chemical formulas and the number and types of atoms are required according to them; thus, we proceed as follows:
<h3>Chemical formulas:</h3><h3 />
In chemistry, we define chemical formulas as expressions showing the types and number of atoms a substance has. The types of atoms are found across the periodic table and the number is defined by the subscripts appearing in the formula.
a. It should be Fe₂O₃ as iron(III) oxide and in such a case it will have two iron atoms and three oxygen atoms.
b. It is potassium permanganate and it has one atom of both manganese and potassium and four oxygen atoms.
c. It should be CH₄, methane, and in such a case, it will have one carbon atom and four hydrogen atoms.
d. It should be NH₄NO₃, ammonium nitrate, and in such a case it will have two nitrogen atoms, four hydrogen atoms and three oxygen atoms.

Answer:
Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol
Explanation:
Activation energy decreases from = 56 kj/mol to 35 kj/mol
products = 78 KJ lower in energy than reactants
Activation energy for the uncatalyzed reverse reaction = 103 kJ/mol
attached below are the sketches of approximate energy-level for both catalyzed and uncatalyzed reactions
