Color the pH paper turns when a small amount of solution is placed on the paper. Dased on the
Students were given as assortment of household chemicals and were tasked with determining the pH of each
substance. The three household substances that Kai was given turned blue litmus paper red. Kai added each substance
to a beaker of water and used a conductivity apparatus to determine if any of the substances conducted electricity.

B)
They are weak bases.
C)
They are electrolytes.

Astudent is performing an experiment comparing sound and light waves. the student gathers the following data. what conclusion does the student most likely make based on this data? light waves always travel the same speed; however, the speed of sound is determined by the medium that it travels through. all sound waves always have the same energy, so the temperature of the medium does not affect wave speed. light needs to vibrate particles, so it travels fastest in tightly packed solids, while sound does not need a medium, so it travels fastest in a gas. tightly packed particles in solids slow down the light waves; however, sound waves make particles bounce into each other, so they travel faster in solids.
