Mr. Conboy wants to figure out which kind of coffee will keep him the most awake (and not lose his marbles) most effectively. Mr. Conboy decides to try different brands of coffee every day and report how awake he feels during each class period for one week.
An effective control for this experiment would be...
What is the same type of coffee maker?
What is the same water?
What is the same time Mr. Conboy drinks the coffee?
What is the same time Mr. Conboy reports how he feels?
Will also accept other reasonable answers.
The property or characteristic of halogens that is responsible for their high reactivity.
What is 7 valence electrons (or the octet rule)?
The nuetron number and electron number of element
Ba-137 -5
What is 81 neutrons?
What is 61 electrons?
The difference between covalent and ionic bonds.
What is donating vs. sharing electrons to satisfy the octet rule?
