What would you call an atom that has more electrons than protons?
Negative Ion
The variable that is measured in an experiment.
Dependent variable
Water is the universal solvent. What does this mean?
It is able to dissolve many different things (because of its polarity)
What letters do most enzymes end in?
ASE
The macromolecule found in vegetable oil
Lipid
How many valence electrons does a neutral atom of Phosphorus (P) have?
5
Experiment: Are test scores impacted by the amount of time spent sleeping the night before a test?
Identify the independent AND dependent variables.
Independent variable = sleep time
Dependent variable = test scores
The reason why oceans stay cooler than sand on hot sunny days
Heat capacity (specific heat)
How does an enzyme speed up a chemical reaction? (Think about the graphs)
It lowers that activation energy.
Carbohydrates/monosaccharide
Lipid/Fatty Acid
Protein/Amino Acid
Nucleic Acid/Nucleotide
Is a neutral atom of Oxygen "happy"? Why or why not?
It is NOT HAPPY because it is two electrons short of a full outer shell
Does dropping a ball from different heights affect how high it bounces?
When testing this question, identify a controlled variable.
type of ball; surface it's dropped onto; ball size...
Why are water molecules polar?
The shared electrons are held closer to the oxygen atom, making the oxygen end negative and the hydrogen ends positive
