Why do water molecules "stick together"?
O
A. The partially positive charges on the hydrogen atoms of two
different water molecules are attracted to each other.
B. The partially positive charge on the oxygen of one molecule
attracts the partially negative charge on the hydrogen of another.
C. The partially negative charge on the oxygen of one molecule
attracts the partially positive charge on the hydrogen of another.
D. The partially negative charges on the oxygen atoms of two
different water molecules are attracted to each other.

Use the drop-down menus to match each part of the scenario to the correct scientific practice. akira records the speed of a reaction without a catalyst and then with a catalyst. akira creates a reaction without a catalyst and repeats the reaction with a catalyst. akira turns in a written lab report to his science teacher. akira wonders, "will adding a catalyst speed up this chemical reaction? " akira writes in his notes that adding a catalyst sped up the chemical reaction because the catalyst lowers the activation energy needed to get the reaction started.
