Explain how a compound such as Magnesium Oxide has a high melting point and conducts electricity when molten

A substantial amount of energy is required to break the strong ionic bonds between the ions Mg^2+ and O^2-. While in a solid state the molecular structure is rigid and does not have any free or mobile electr...

Calculated the Relative Molecular Mass of calcium (II) chloride using the periodic table.

Calcium (II) has a charge of 2+ and each chloride has a -1 charge giving a formula of CaCl2 when balancing the charges out. Ca (Relative Atomic Mass) = 40.08 and Cl (Relative Atomic Mass) = 35.45So Relative ...

Using the % yield calculation (please state), what is the percentage yield for the reaction of calcium oxide with water to produce calcium hydroxide if the theoretical yield is 4.0g but only 1.5g is produced?

The equation for percentage yield is as follows: % yield = ([Actual mass of product obtained]/[Maximum theoretical mass]) x 100 Therefore using this equation, we can obtain the % yield by inputting the actua...
