What is the chemical equation
Serggg [28]

Chemical equation is the symbolic representation of chemical reactions.

Explanation

Chemical reactions are known as the reaction where two or more molecules or compounds react with each other leading to formation of product compounds along with either release or absorption of energy.

The symbolic representation of the processes occurring in a chemical reaction is termed as chemical equation.

The symbolic representation includes the reactants, products, external energy type and quantity of external energy and also about release of energy if occurs.

So the reactants are usually written in the left side of the chemical equation whereas on the right the products are written.

Both the sides are linked by a single headed arrow mark.

Some both the sides are linked by double heated arrow mark indicating the equilibrium chemical reaction.

At STP, fluorine is a gas and iodine is a solid. This observation can be explained by the fact that fluorine has
motikmotik
<span>The answer is 4. The molecules of each material entice each other over dispersion (London) intermolecular forces. Whether a substance is a solid, liquid, or gas hinge on the stability between the kinetic energies of the molecules and their intermolecular magnetisms. In fluorine, the electrons are firmly apprehended to the nuclei. The electrons have slight accidental to stroll to one side of the molecule, so the London dispersion powers are comparatively weak. As we go from fluorine to iodine, the electrons are far from the nuclei so the electron exhausts can more effortlessly misrepresent. The London dispersion forces developed to be increasingly stronger.</span>

Uses of baking powder​
NARA [144]

Baking powder is used to increase the volume and lighten the texture of baked goods. It works by releasing carbon dioxide gas into a batter or dough through an acid–base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture.

SEP Develop Models Each helium atom has two protons. Sketch models
RSB [31]

Protons and neutrons are located in the nucleus of the atom while the electrons move in the trajectory of the shell

<h3>Further explanation   </h3>

Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.  

So Isotopes are elements that have the same Atomic Number (Proton)  

Isotopes of Helium : helium-3 and helium-4

  • ₂³He :

protons = 2

electrons=protons=2

neutron=mass number-atomic number=3-2=1

  • ₂³He :

protons = 2

electrons=protons=2

neutron=mass number-atomic number=3-2=1

  • ₂⁴He

protons = 2

electrons=protons=2

neutron=mass number-atomic number=4-2=2

Protons and neutron in the nucleus, electrons in the shell
