Answer A material that decreases the rate of a reaction. The amount of energy that reactants must absorb before a chemical reaction will start also called free energy of activation. What role does activation energy pay in chemical reactions? Activation energy is the energy absorbed before it can start a chemical reaction.

Answer:
B. Identifying the types of data to be gathered
Explanation:
Identifying the types of data to be gathered is one of the part of designing a set of experimental procedure.
An experimental procedure is a methodical process that must be followed in order to attain the goal of the experiment.
- As with most experiments, data is collected for further analysis and interpretation.
- The choice of way of collecting data and the type of data to be collected is very important when designing an experiment.
Answer:
1.) Liquid
2.) Low
3.) Molecular
4.) Surface tension
5.) Solvent
Explanation:
Water is important to living things because it remains in the LIQUID state over a wide range of temperatures. Water in lakes and oceans does
not experience large temperature changes because liquid water has a
LOW specific heat, so it must absorb or release a lot of energy as its temperature changes. The MOLECULAR forces between water
molecules cause water to form round droplets and cause water's high SURFACE TENSION. Water is also an important SOLVENT because it can
dissolve many different substances.

This depends on what are the values of Tonya's data. We can say that it is precise if the all data points are almost located at one area and it can be near or far from the accepted value. We can say that it is accurate when the data are near or equal to the accepted value.
