Yes, it is the power of material evidence that wins.
- Evidence used to support or refute a scientific theory or hypothesis is known as material evidence.
- Evidence is also used by scientists in various contexts, such as when they apply ideas to real-world issues.
- Whether a person accepts the data as proof depends on their presumptions or views regarding how observations relate to a theory.
- A creative hypothesis is developed by a scientist and may be refuted by testing it against evidence or established truths.
- Evidence can refute a hypothesis by demonstrating facts that are at odds with it. In contrast, the presence of evidence does not preclude the possibility of future, undiscovered evidence supporting the idea.
Therefore, it is the power of material evidence that wins, not the authority of experts that
proves an answer in Science.

Answer:
balanced equation mole ratio 5 2 mol NO/1 mol O2
10.00 g O2 3 1 mol O2/32.00 g O2 5 0.3125 mol O2
20.00 g NO 3 1 mol NO/30.01 g NO 5 0.6664 mol NO
actual mole ratio 5 0.6664 mol NO/0.3125 mol O2 5 2.132 mol NO/1.000 mol O2
Because the actual mole ratio of NO:O2 is larger than the balanced equation mole
ratio of NO:O2, there is an excess of NO; O2 is the limiting reactant.
Mass of NO used 5 0.3125 mol O2 3 2 mol NO/1 mol O2 5 0.6250 mol NO
0.6250 mol NO 3 30.01 g NO/1 mol NO 5 18.76 g NO
Mass of NO2 produced 5 0.6250 mol NO2 3 46.01 g NO2/1 mol NO2 5 28.76 g NO2
Excess NO 5 20.00 g NO 2 18.76 g NO 5 1.24 g N
Explanation:
The semi will have the hardest time changing direction because of its mass. The more mass there is, the more effort it takes to accelerate and decelerate as well as change direction.
The answer is C. A, B, and C would depend on what type of electron it is.
