Never let anyone tell you, or believe any scientific claim that has the word "all" in it. Getting to the point, carbon is the most common element in any biochemically active molecules. Organic chemistry is the chemistry of carbon based reactions and mechanisms, and since the word organic is referring to the Greek word organikos meaning characteristic of, pertaining to, or derived from living organisms. So I think your answer is carbon. Hope that helps.
a chemical change
it must be cleared that while writing a chemical equation... it must be in symbols of that element then the numbers of the atoms used in the reaction must be equated to both the sides that is it must be equal to right hand side as well as left hand side... we need to remember the symbols of that element
There has to be the same amount of atoms of each element on each side of the equation.
An element must have similar chemical properties and valency as the element it is replacing in order to replace it in a compound. This ensures that the chemical reaction remains balanced and the new compound formed is stable.
For an element to stay the same, the number of protons in its nucleus (atomic number) must remain constant. This defines the element's identity on the periodic table and determines its unique chemical properties.
No, molecules are not equal in a chemical equation. The number of atoms of each element on the reactant side must be equal to the number of atoms of the same element on the product side for the equation to be balanced.
To obtain an element from its compound ore, the ore must undergo a process called extraction. This typically involves crushing the ore, heating it to high temperatures, and then using chemical reactions or other separation techniques to isolate the desired element in its pure form. The extracted element can then be further processed and refined as needed.
Nothing. You're probably thinking of CH3COOH (also referred to as CH3CO2H or C2H4O2), which is acetic acid.
the two atoms must be of the same element
All atoms of the same element have the same number of protons, which is its atomic number. A neutral atom will have the same number of electrons as protons.
The number of atoms for each element must be the same on both sides of a balanced chemical equation. This ensures the law of conservation of mass is upheld, meaning that no atoms are created or destroyed during a chemical reaction.
Chemical equations are balanced to satisfy the law of conservation of mass, which states that mass cannot be created or destroyed in a chemical reaction. This means that the number of atoms of each element present in the reactants must be equal to the number of atoms of the same element in the products. Balancing ensures that the reaction equation accurately represents the substances involved and the quantities of each element present.
