How many valence electrons are there in sulfur, and iodine.
Vinil7 [7]

Today I will explain what a valence electron is and how many valence electrons each of the atoms your asking about have. :)

→ A valence electron is an electron in the outer shell of an atom that is able to participate in bonding. While iodine has 53 electrons, all but seven are in the inner shells of the iodine atom.

→ Sulfur has sixteen electrons in total, two in the inner shell, eight in the middle, and six in the outer. This means that sulfur has six valence electrons.

Methanogenic bacteria convert acidic acid (CH3COOH) to CO2(g) and CH4(g)
Y_Kistochka [10]

The enthalpy of the reaction can be obtained from the enthalpies of formation as  -16.2 kJ/mol.

<h3>What is the enthalpy of reaction?</h3>

We know that any time that there is a chemical  reaction, there is an interaction that place between the reactants and the products and as such we are going to get new substances and these are the substances that I have referred to here as the products of the reaction.

In this case, we are asked to obtain the enthalpy change of the reaction. This tells us the heat that could have been absorbed or evolved in the reaction. We have to at this point know that the enthalpy change of the reaction gotten from;

Sum of enthalpy of the products - Sum of enthalpy of the reactants

ΔH = [(-484.5)] - [(-393.5) + (-74.8)]

ΔH = (-484.5) + 468.3

ΔH = -16.2 kJ/mol

Why do canned baked beans last longer in a can than in air?
Alinara [238K]
Because when anything is exposed to air, it come in contact with bacteria which begin to break down the proteins in the beans. But when it’s in a can, it can’t get exposed to bacteria which means it won’t break down.

Hope this sheds some light ♥︎
