How can you distinguish a from b?
in this lab, you will do experiments to identify types
of changes. using the question format you learned
(shown above), write an investigative question that
you can answer by doing these experiments.

The volume of helium in a blimp is 6.28 x 10^9 millimeters. the density of helium in the blimp is .1786 kilogram/meter^3. find the mass of the helium in the blimp.

What is the mass of 0.46 mol of mgcl2

Some familiar products contain some of the same types of atoms. for instance, the chemical formula for baking soda is nahco 3. the chemical formula for liquid bleach is naclo, and the chemical formula for table salt is nacl. which choice best describes why these three products have some of the same types of atoms in common?
