1. sketch a ball and stick diagram of a water molecule. label the atoms and indicate the partial charges…

Brief Explanations:

A water molecule ($H_2O$) has one oxygen atom and two hydrogen atoms. Oxygen is more electronegative than hydrogen, creating a polar - covalent bond. The oxygen has a partial negative charge ($\delta-$) and the hydrogens have partial positive charges ($\delta+$). In a ball - and - stick diagram, the oxygen atom is usually represented as a larger ball and the hydrogen atoms as smaller balls. The sticks represent the covalent bonds between the atoms.

Answer:

Draw a larger ball labeled 'O' for oxygen and two smaller balls labeled 'H' for hydrogen. Connect each hydrogen ball to the oxygen ball with a stick to represent the covalent bonds. Mark the oxygen atom with a $\delta-$ to indicate its partial negative charge and each hydrogen atom with a $\delta+$ to indicate their partial positive charges.
