⦁ Calcium reacts with water as shown. Ca(s) + 2H2O(l) → Ca(OH)2(aq) + H2(g)

What is the total mass of the solution that remains when 40 g of calcium reacts with 100 g of water?

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

Take a look at this dandelion. the yellow flower on the right is pollinated and the seeds on the left are transported by

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.
