When rocks break down because of chemical reactions it is called chemical weathering. The rocks are weakened and subsequent disintegration of rock by chemical reactions. They can be oxidation, hydrolysis and carbonation.
Answer : Option A) HF.
Explanation : Assuming the complete question as per the attachment.
H-F bonds are formed because of hydrogen bonding between H atom and F atom and is considered to be strongest amongst the rest other options given.
As given in the table it is clear that the molar mass of HF molecule is the lowest. It shows that, when dispersion increases in the molecule molecular weight also increases.
Niels Bohr
Ernest Rutherford
John Dlaton
Neil Bohr is the scientist who invented a model of the atom that most closely resembles the modern electron cloud model.
An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answer: Red Plate Dinner
Explanation:
If we calculate them with formula for area of circle().
Red Plate - = 36
2 Yellow Plate - 2 * = 2 * 9 = 18
The Red Plate has a bigger area, so the Red plate has more area.
Please mark as brainliest, and take care.
B. 1 kiloparsec
C. 1 light-year
D. 1 AU
The distance between the Earth and the Sun is approximately 1 AU (Astronomical Unit). Therefore, option D is correct.
One AU is defined as the average distance between the Earth and the Sun, which is about 93 million miles (150 million kilometers). It is a convenient unit of measurement for distances within our solar system.
A parsec is a unit of distance used for objects outside our solar system, equal to approximately 3.26 light-years. One kiloparsec is equal to 1,000 parsecs, or approximately 3,260 light-years. Therefore, neither A nor B is the correct answer.
A light-year is the distance that light travels in one year, which is approximately 5.88 trillion miles (9.46 trillion kilometers). Therefore, C is also not the correct, as the distance between the Earth and the Sun is much less than one light-year.
Therefore, the correct answer is D. 1 AU
