Lab: Properties of Elements
Properties of Ionic and Covalent Bonds. Problem: How are the properties of Ionic and Covalent bonds similar and different? 8th Grade Science Standards: Each of the more than 100 elements of matter has distinct properties and a distinct atomic structure.
Determination of the Configuration
OPTICAL ISOMERS. DETERMINATION OF THE CONFIGURATION. The determination of the configuration around an asymmetric carbon is dictated by the priority of the groups attached to the asymmetric carbon. The group priorities are assigned according to the atomic.
1) Determine Mass of Water Driven Off
Problem #1: A 15.67 g sample of a hydrate of magnesium carbonate was heated, without decomposing the carbonate, to drive off the water. The mass was reduced to 7.58 g. What is the formula of the hydrate? 1) Determine mass of water driven off. 15.67 minus 7.58 = 8.09 g of water.

Stoichiometry Involves Quantitative Relationships That Are Based on Mole Quantities In
Stoichiometry involves quantitative relationships that are based on mole quantities in a balanced equation. Dimensional analysis is a way of translating a measurement from one unit to another unit. The Law of Conservation of Mass allows us to predict the products of a chemical reaction.
