Answer:
They're different - heat and thermal energy. ... The heat, in turn, speeds up the molecules within the pot and the water. If you place a thermometer in the water, as the water heats up, you can watch the temperature rise. Again, an increase in internal energy will result in an increase in temperature.
The given compound is
Each formula unit of has 2 mol Potassium (K) atoms, 2 mol Chromium (Cr) atoms and 7 mol Oxygen (O) atoms.
Atomic weight of potassium is 39.0983 amu
Atomic weight of Chromium is 51.9961 amu
Atomic weight of Oxygen is 15.9994 amu.
Therefore the formula weight of
= 294.1846 amu
Answer:
Explanation:
Briefly, the scientific process starts by making an observation of a phenomenon, which leads you to question what is happening, and then to formulate a hypothesis.
The hypothesis is a reasonable explanation of the phenomenon, which relates a cause and a consequence, and that can be testable, and can result to be true or false.
Then, you design an experiment to test the hypothesis.
The experiments will give you a set of data which must be interpreted to conclude whether your hypothesis was true or false. This may be seen as the final step of the process, which gives the outcome of the scientific process. This conclusion must be based on reliable data and a logical.
If, your conclusion is clear, logically deducted from the data, using a correct analysis, your experiment was succesful. No matter whether the hypothesis resulted true or false.
Nevertheless, this is not really the final step, as now sharing the information with the scientific community is very important. I t might also happen that you want to iterate the process, to test a new hypothesis.
Answer:
Some of KCl will precipitate out of the solution.
Explanation:
Gases solubility increases with decrease in temperature and therefore nitrogen gas will not bubble out is the temperature is dropped from 75 deg C to room temperature.
On the other hand, KCL is a salt in solid state and the solubility of solids decreases with decrease in temperature. Therefore some of the KCl will precipitate out of the solution when temperature drops from 75 deg C to room temperature.
Answer:
Carbon Dioxide
