Read each scenario and determine the cause of invalid data. Renata wants to survey her 30 classmates about their favorite hobby. Her data can contain only 13 data points. Nev forgot to write down one data point, so he made it up. Keith accidentally left out a step when writing his experimental procedure. Adele recorded the distance between two objects in inches rather than centimeters

Describe the difference between a. a hypothesis and a theory and b. an observation and an experiment.

An atom of lithium (li) and an atom of chlorine (cl) engage in a chemical reaction. which correctly describes the structure of the resulting chemical compound? hint: consider the class of each element. the chemical compound will have a network structure. the chemical compound will have triple bonds. the chemical compound will have a ball-and-stick structure. the chemical compound will have double bonds.

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
