Me with a couple of ! you : ) 1. what is a chemical reaction? a. any time a substance is mixed with another substance b. any time different substances combine to form a new substance, or when a substance breaks up into different substances c. any time a substance is heated, frozen, or evaporated 2. balancing chemical equations is called: a. stoichiometry b. chemolibrium c. equivalentry 3. sulfuric acid is made of two hydrogen atoms (h), one sulfur atom (5), and four oxygen atoms (0). what is its formula? a. 2h4s0 b. h4s20 c. h2s04

If this equation was completed which statement would it best support

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.

In which phase(s) do the molecules take the shape of the container?
