What does the formula for table salt NaCl tell you about that compound?

Sodium chloride , commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. In its edible form of table salt, it is commonly used as a condiment and food preservative.

What does the formula for water H2O indicate about that compound?

Sample Molecular Weight Calculation The chemical formula for water is H2O, which means this molecule has 3 atoms: 2 of hydrogen (H) and 1 oxygen (O) atom.

Is salt water NaCl H2O a compound?

Saltwater is a homogeneous mixture, or a solution. Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound.

What happens when table salt NaCl dissolve in water?

When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

What is the formula of salt water?

The chemical composition of sea water is relatively simple to interpret – it’s H2O with a few extras. If you collect a sample of ocean water and take it to the laboratory, a chemist will quickly identify six major ions.

What is H2O on the periodic table?

The chemical symbol for water is H2O. The atomic number of oxygen is 8, which means that it has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, and 4 electrons in the 2p orbital, in accordance with the Periodic Table of the Elements in Figure C-7.6.

How are the compounds NaCl and h2o different?

Water (H2O) is a molecular compound because it is a substance made from more than one kind of element that is held together with molecular bonds. Salt (NaCl) is an ionic compound because it is a substance made from more than one kind of element that is held together with ionic bonds.

What compounds are in salt water?

Chemical and physical properties of seawater The six most abundant ions of seawater are chloride (Cl−), sodium (Na+), sulfate (SO24−), magnesium (Mg2+), calcium (Ca2+), and potassium (K+). By weight these ions make up about 99 percent of all sea salts.

What is the formula for water?

When two hydrogen atoms are bound to an oxygen atom, the outer electron shell of oxygen is filled. Encyclopædia Britannica, Inc. Learn why fresh water and seawater have different freezing points. Although its formula (H2O) seems simple, water exhibits very complex chemical and physical properties.
