Answer #1

Answer:

The main difference between a population and sample has to do with how observations are assigned to the data set.

  • A population includes all of the elements from a set of data.
  • A sample consist one or more observations drawn from the population.

Depending on the sample method, a sample can have fewer observations than the population, the same number of observations, or more observations. More than one sample can be derived from the same population.

It is often difficult to tell whether a reaction is exothermic (gives off heat) or endothermic (takes in heat) just by looking at it. For the following reaction, describe what information you would need to know about specific bonds (be specific about numbers of bonds, bonds breaking and being formed, etc.) to tell whether the reaction is exothermic or endothermic: 2 CuO (s) + NO (g) ? Cu2O (s) + NO2 (g)
