If you have time, travel to the testing center first to ensure you know how to get to the correct building, where to park, and where your test room is. Having all these logistics out of the way will help reduce your stress on test day—and ensure you aren’t late!
Although the importance of spatial thinking may be most obvious in geology, it is equally important in other STEM fields. For example, a great deal of attention is devoted in chemistry to the study and behavior of isomers, which are compounds with identical molecular compositions, but different ...
TECHNICAL Fire Facts You Need to Know Fire is perhaps the most useful phenomenon ever discovered by mankind. Early man learned to make productive use of fires engendered naturally by lightning, material ejected by volcanoes and other natural occurrences. T...
atom of the second layer to a first layer atom regardless of its atomic number. For example, in the following molecule, layer 1 is a tie so we proceed to layer 2 which gives the priority to the carbon connected to the chiral center on the left since it has an oxygen connected to it...
“valency” – the term still used to this day. For example, hydrogen can only bond with one other atom and thus has a valence of one; sulfur has a valence of 2, Nitrogen 3, Carbon 4 and so on. Today, we know thatvalencyresults from the number of electrons in an atom’s outer ...
