Answer:
a compound is a syllable in the outer world
Explanation:
When an atom donates electrons and other gains electrons, they form ions and the bond is called the ionic bond. When the atoms share electrons between them, they form a molecule, and the bond is called the covalent bond.
The atoms can share one, two or three pairs of electrons in the same bond. If one pair is shared it's called a single bond or a covalent simple; if two pairs are shared it's called a double bond or a covalent double, and if three pairs are shared it's called a triple bond or a covalent triple.
If this helps, please mark me as brainly, if not thats ok. im just here to help you get good grades. :D
Answer:
The relative number of products and reactants
Explanation:
- The numerical coefficients in chemical equations show the ratio of the molecules of each substance involved in a chemical reaction that is both reactants and products.
- The coefficients in a balanced chemical equation indicate the relative number of moles of reactants and products.
- Additionally, coefficients are important to prove the law of conservation of mass.
