Thermal energy is caused by the motion of (a) mixing water molecules contained in a beaker. (b) molecules in solid, liquid, and gas phases. (c) mixing two different molecules together. (d) molecules that have reached equilibrium.

Which of the following is true for the actual yield of a reaction? it is always calculated as a ratio. it is the yield from the excess reactant. it is the yield from the limiting reactant. it is always less than the theoretical yield.

Part 1: include important facts found through your research. part 2: include your visual display. include your summary of “the chemistry of water” from the national science foundation website. include your experiment. part 3: include responses to the reflection questions.

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.
