Explanation:

It correctly reads;

A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%). Answer:

1. Explain why the energy transfer is not the same between the three tests of the experiment.

2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.

2. A hypothesis is an educated guess based upon observation. It is an explanation of a single event based upon what is observed.
uranmaximum [27]

A law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.

<h3>What exactly is a hypothesis?</h3>

A hypothesis is a guess based on a large amount of background information. If only five trees survived, they may have received more light than the other five.

In that case, one will devise an experiment in which the same plant is randomly assigned to different treatment groups with varying degrees of light, and the rate of growth of each group is compared.

Thus, a law is supported by scientific evidence that is reproducible, whereas a hypothesis is simply a guess that can be confirmed or refuted by an experiment.
