As part of an investigation, students combined substances in a beaker to observe chemical reactions. They measured the mass of each substance before and after the reaction. The mass of the reactants was 50.0 grams and the mass of the products was 48.2 grams. Assuming the students did not make any careless errors, what likely explains the change in mass?

What is the number of neutrons in an atom with atomic mass of 35

What does an electron configuration for an atom relate to the atoms placement on the periodic table

Some molecular compounds, such as hcl, ionize completely in solution. for molecular compounds such as h2co3, most molecules do not ionize in solution. which describes the properties of these two solutes? a. hcl and h2co3 have the same effect on the properties of the solution. b. hcl raises the freezing point of water more than h2co3 does. c. hcl raises the boiling point of water more than h2co3 does.
