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:
The products react to reform the original reactants
E.g. Haber process of ammonia production
Answer:
The volume of hydrogen gas produced at STP is 4.90 liters.
Explanation:
![2Al (s) + 6 HCl (aq)\rightarrow 2 AlCl_3 (aq) + 3 H_2 (g)](https://tex.z-dn.net/?f=2Al%20%28s%29%20%2B%206%20HCl%20%28aq%29%5Crightarrow%202%20AlCl_3%20%28aq%29%20%2B%203%20H_2%20%28g%29)
Moles of aluminium =![\frac{3.60 g}{27 g/mol}=0.1333 mol](https://tex.z-dn.net/?f=%5Cfrac%7B3.60%20g%7D%7B27%20g%2Fmol%7D%3D0.1333%20mol)
According to reaction , 2 moles of aluminium gives 3 moles of hydrogen gas.
Then 0.1333 moles of aluminium will give:
of hydrogen gas
Volume of 0.2 moles of hydrogen gas at STP = V
Temperature at STP = T = 298.15 K
Pressure at STP = P = 1 atm
n = 0.2 mol
PV = nRT (Ideal gas equation)
![V=\frac{nRT}{P}=\frac{0.2mol\times 0.0821 atm L/mol K\times 298.15 K}{1 atm}=4.8956 L\approx 4.90 L](https://tex.z-dn.net/?f=V%3D%5Cfrac%7BnRT%7D%7BP%7D%3D%5Cfrac%7B0.2mol%5Ctimes%200.0821%20atm%20L%2Fmol%20K%5Ctimes%20298.15%20K%7D%7B1%20atm%7D%3D4.8956%20L%5Capprox%204.90%20L)
The volume of hydrogen gas produced at STP is 4.90 liters.
