water, carbon dioxide, sulphuric acid
Chemical symbols for compounds are written by combining the chemical symbols of the elements in the compound, along with subscripts to indicate the number of atoms of each element present. For example, water (H2O) is composed of two hydrogen atoms and one oxygen atom. The chemical symbols are always listed with the element that appears first in the compound listed first.
The groups of symbols are called "formulas" (Latin formulae) because they show the symbols of the elements and ions that are in a molecule of a compound.Example: CO2 (carbon dioxide) contains one atom of carbon and two of oxygen.
The periodic table displays the symbols and atomic numbers of the elements along with information about their atomic masses and electron configurations. It organizes the elements based on their properties and allows for easy identification of trends in chemical behavior across rows and columns.
A chemical formula is a shorthand notation that represents the elements present in a compound along with the number of atoms of each element. It uses chemical symbols and subscripts to convey this information in a concise manner.
Elements are represented by symbols which are based on their names, sometimes the symbols are based on old versons of their names... examples of element symbols are...Oxygen = OHelium = HeNitrogen = NSodium = Na (its old name was Natrium)Gold = Au (its old name was Aurum)Compounds are represented by the sumbols and proportions of the elements they contain, examples are...NaCl = Sodium Chloride (salt), one atom of Sodium plus one atom of Chlorine.H2O = Water, two atoms of Hydrogen plus one atom of Oxygen.HNO3 = Nitric Acid, one atom of Hydrogen plus one atom of Nitrogen plus three atoms of Oxygen.
Compound leaves are divided into multiple leaflets along a central stalk, while simple leaves consist of a single leaf blade attached to the stem.
Muscovite mica is a mineral, specifically a type of phyllosilicate mineral, and it is not an element or a simple compound. It is composed of several elements, primarily potassium, aluminum, silicon, and oxygen, along with hydroxyl groups. Its complex structure includes layers that can easily split, giving it its characteristic mica properties.
Date leaves are considered simple leaves. Each leaf consists of a single leaf blade that is divided into numerous leaflets, which are arranged along a central stalk. This structure classifies them as simple leaves with a compound appearance due to the presence of these leaflets.
Dogwood trees have large, sort of teardrop-shaped simple leaves, with long veins running parallel along the length of the leaf.
A mango leaf is a compound leaf. Compound leaves consist of multiple leaflets attached to a single leafstalk or petiole. In the case of mango leaves, there are several leaflets arranged along a central stem.
Water is not an element. It is a compound of Hydrogen and Oxygen.
Coal is not a compound. It is a naturally occurring solid fossil fuel that primarily consists of carbon along with small amounts of other elements like hydrogen, sulfur, and oxygen.
