Rate this question:
Ionic bond
Covalent bond
Uneven bond
Hydrogen bond
Eternal bond
Rate this question:
The independent variable in the experiment is the study guide.
The dependent variable in the experiment is the performance of the students on the test.
The control in the experiment is the class that did not receive a study guide.
The data (average test grades on a 0-100 scale) is going to be qualitative.
Rate this question:
They share their electrons evenly.
They cannot form hydrogen bonds.
Since they don't form hydrogen bonds, they tend to heat up more slowly than water does.
They do not have positive and negative regions like polar molecules do.
