Answer:
The entity that decreases is the Weight.
Explanation:
Every object on the surface of the earth is usually pulled downwards by the action of gravity. The force or weight is W = mg
Now, the farther one gets away from the surface of the earth by climbing a mountain, the further the person is from the Earth's centre of gravity.
We know that the formula for Force of gravity away from the Earth's surface is given by;
F_g = GM1M2/r²
So the greater the distance, the lesser the gravitational force.
Now, the gravitational force equals the weight of the individual.
Thus, the entity that decreases is the Weight of the individual.
The oxidation numbers for Nitrogen are respectively -3, +5, +4
Answer:
C2H6N2O
Explanation:
Mass of carbon = 12g /44g/mol * 5.134 g = 1.4 g
Number of moles of carbon= 1.4 g/12g/mol = 0.12 moles
Mass of hydrogen = 2 g/18g/mol * 3.173 g = 0.35 g
Number of moles = 0.35 g/1 g/mol = 0.35
Mass of nitrogen= 37.82/100 * 4.319 g = 1.6 g
Number of moles = 1.6 g/14g/mol = 0.11
Mass of oxygen = (4.319) - (1.4 + 0.35 + 1.635) = 0.934 g
Number of moles = 0.934 g/16 g/mol = 0.058 moles
The lowest ratio is 0.058
Dividing through;
C- 0.12/0.058 = 2
H - 0.35 / 0.058= 6
Nitrogen - 0.11/0.058 = 2
O- 0.058 moles/0.058 = 1
Hence he empirical formula is;
C2H6N2O

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.
