Answer:
The answer to your question is 9.034 x 10²³ molecules
Explanation:
Data
number of molecules = ?
number of moles = 1.50
Process
To solve this problem, use Avogadro's number. This number relates 1 mol of a substance to 6.023 x 10²³ molecules.
1 mol of CO₂ --------------- 6.023 x 10 ²³ molecules
1.5 moles of CO₂ ---------- x
x = (1.5 x 6.023 x 10²³) / 1
x = 9.034 x 10²³ molecules
Answer:
The scientists use results from the new experiments to change the existing explanations of how nature functions. The world is changing continuously. There are outcomes, which have been obtained from the scientific studies performed earlier, which may no longer be accurate at present because of certain factors that may not have been discovered or present in those times. Other scientific findings may also be further acknowledged as true from the outcomes of the new experiments.
Scientists use results from new experiments to validate or refute existing theories and to explore new scientific territory. This is done by gathering and analyzing data from these experiments, ultimately leading to more informed and detailed theories.
Scientists use results from new experiments to both confirm existing theories and explore new territories of knowledge. Conducting an experiment helps scientists gather data and observations. These results then provide evidence that either supports or refutes a hypothesis, leading to more advanced and precise scientific theories. For example, when Albert Einstein proposed his theory of relativity, further experiments such as the Eddington experiment during a solar eclipse provided data evidence that supported his theory.

When the formation of a substance is negative, it means that it releases heat to the surroundings. When it releases heat to the surroundings, the reaction is exothermic. When it absorbs heat from the surroundings, the reaction is endothermic.
