Answer:
The Following are the matching to this question:

Explanation:
- It includes creating assumptions, extracting predictions through logical outcomes, and experimentation observation based on those projections.
- Every information gathered only with sense is also an observation. It expresses concern relating to scientific research. It also helps research scientists gather data.
- Its independent variable inside an analysis is a controlled variable. It's also called "manipulated," because it can change its parameter, which is controlled one.
- The suggested explanation for an occurrence is a hypothesis. It belongs to the scientific method. That's an experimental forecast, which is checked.
- The experiment manipulates the important variables, calculates the dependent variable, controls any alien variables.
- It "reacts" to improvements inside an experiment that they make. It is the result or consequence of an experiment.
Answer:
-145.2kJ
Explanation:
Enthalpy is an extensive property as its value depends on the amount of substance present in the system.
If the enthalpy for one mole of methanol = -726 kJ/mol;
The Enthalpy for 0.2 mol is given as;
Enthalpy = 0.200 * 726
Enthalpy = -145.2kJ
It would take -145.2kJ for 0.200 mol of methanol to undego the combustion reaction.
Hi,
