Imagine you are a scientist working in a lab and you need to create a solution for an experiment. You decide to start with the basics and first create water. What is the correct chemical formula you should use for water?
H2O
HO2
H2O2
2H1O
Imagine you're making a cup of tea. When you dissolve sugar into the water, the sugar molecules spread evenly throughout. What property of water allows this to happen?
it is a molecule with opposite charges on opposite ends
it is a molecule with no charge
it is a molecule with identical charges on opposite ends
it is a molecule with too many protons
When you place a straw into a glass of water, what is the term for the phenomenon that allows water to climb up the straw against gravity?
Capillary Action
Specific Heat
Universal Solvent
Magic
A water strider can skate along the top of a pond because:
covalent bonds result in water cohesion (surface tension)
hydrogen bonds result in water cohesion (surface tension)
water striders have adapted to take advantage of water cohesion
water striders are afraid of water and avoid it
Why does an ice cube float in a glass of water?
water expands when it freezes, making ice less dense than water
water compacts when it freezes, making ice more dense than water
hydrogen bonds in water push the ice to the surface
ice is afraid of water, and avoids it
