Characteristics of reliable scientific explanations are present in the development of the atomic theory in the given passage.
<h3>What is atomic theory?</h3>
Atomic theory is the scientific theory that matter is composed of particles called atoms.
The discoveries of subatomic particles such as;
- electron by J.J. Thomson
- proton by Ernest Rutherford
- neutron by James Chadwick
- nucleus by Ernest Rutherford
all contributed in the development of the atomic theory.
From the information given in the passage J.J. Thomson experiment gave rise to atomic model while Rutherford, Geiger and Ernest Marsden, performed the experiment that discovered nucleus and proton.
Thus, characteristics of reliable scientific explanations are present in the development of the atomic theory in the given passage.

Answer:
K= 44.018%; S= 19.957%; O= 36.025%

For
a first-order reaction, the rate law would be expressed as:<span>
r = dC / dt = -kC
Integrating it from time zero and
the initial concentration, Co, to time, t, and the final
concentration, C. We will obtain the first-order integrated law as follows:
ln C/Co= -kt
To determine the concentration of N2O in the system at a certain time, we simply substitute the given values from the problem statement
as follows:
</span>ln C / Co = -kt<span>
ln C / 10.9 = -0.76 (9.6)
e^ln C / 10.9 = e^-0.76 (9.6)
C / 10.9 = 6.78 x 10^-4
C= 7.39 x 10^-3 m
<span>
Therefore, the concentration of N2O in the system after 9.6 s would be 7.39 x10^-3 m.

Answer:
The incorrect statement is option B and D.
Explanation:
Carbohydrates are more generally is known as the sugars that are composed of the carbon, hydrogen and oxygen atoms. Monosaccharides are the single unit of carbohydrates while disaccharides are the sugars that contain two molecules of the sugar and similarly saccharides with multiple sugars are called polysaccharides. The general chemical formula of the carbohydrates Cn(H2O)n, however the complex sugars does not follow this formula. Amino sugars are contains NH2 in their formula so carbohydrates not necessarily contains only H, O, AND C always.
Thus, the incorrect answer is - option B and D.
Answer:
If the reactants in the chemical reactions are known, then the products can be predicted because the pattern of the chemical reactions is being followed. The pattern for a single replacement is A + BC --> AC + B. This is like the Hear It Pop Chemical Reaction which is also an example of the single replacement.
