Answer:
Identify the "given" information and what the problem is asking you to "find."
Given : Cl2O7
Find: % Composition (% Cl and %O)
List other known quantities.
Mass of Cl in 1 mol Cl2O7 , 2 Cl : 2 x 35.45 g = 70.90 g
Mass of O in 1 mol Cl2O7 , 7 O: 7 x 16.00 g = 112.00 g
Molar mass of Cl2O7 = 182.90 g/mol
Bonds are forces of attractions between atoms formed by the transfer of electrons or sharing of electrons. Metallic bond is a type bond that exist in metallic structures where the atoms of the metals attracts the sea of electrons in the structure.It is these metallic bonds that results to the malleability , ductility and conductivity of metals because in that the sea of electrons makes them conduct electricity. In addition the atoms of metals in the structure are ions which can slide past each other in the sea of electrons.
Answer:
It will be a pure substance (compound) because chemical composition of sugar crystals will be the same whether obtained from sugarcane or from beet root.

<span>Bases can both take up hydrogen ions and release hydroxide ions. This differs from an acid, which releases a hydrogen ion. Combining acids and bases can produce a lot of heat during the reaction. If the acid and base are of the same strength, the mixture will be neutralized.</span>
No elements visible!
Ions form between metals and non-metals.
Hope this helps!
