Asubstance that contains two or more substances combined chemically is called

A substance which has two or more substances combined chemically is called pure chemical compounds.

Explanation:

When two or more substances combined together a new substance is formed. If this combination occurs chemically it is called as pure chemical compound.

These pure chemical substances are have same properties throughout sample. A pure substance take part in a chemical reaction to shape in expected products.

Water, table salt, Baking soda and table salt are chemically pure substances. Pure water is one of the example for pure chemical substance.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
