The purpose of the scientific method "to use an experiment to test a scientific theory".
<u>Answer:</u> Option C
<u>Explanation:</u>
Researchers use the scientific method when conducting experiments to collect observable, empirical data in a hypothesis-related experiment , the findings that tend to justify or oppose a theory. It's also very important that other researchers can repeat and independently verify the conclusions, logic, and experiments.
Scientific method retains inductive reasoning its position. Scientists use this to formulate theories and hypotheses. In order to adapt the ideas to particular situations, deductive reasoning allows them to do so. Overall scientific methods have become path of analyzing different processes, going in our environment.
Answer:
10.07 L is the volume for the produced N₂
Explanation:
This is a question for the Ideal Gases Equation:
P . V = n . R . T
In STP conditions, the pressure is 1 atm and the T° is 273K
Let's determine the moles of produced N₂ by the decomposition of TNT
The reaction is:
2 C₇H₅(NO₂)₃ (s) → 7 C (s) + 7 CO (g) + 3 N₂ (g) + 5 H₂O (g)
We convert the mass to moles (mass / molar mass)
68.2 g . 1 mol / 227.13 g = 0.300 moles
Ratio is 2:3. 2 moles of TNT can produce 3 moles of N₂
Then, 0.300 moles will produce (0.300 . 3) / 2 = 0.450 moles
We replace data:
1 atm . V = 0.450 mol . 0.082 L.atm/mol.K . 273K
V = (0.450 mol . 0.082 L.atm/mol.K . 273K) / 1 atm
V = 10.07 L
