Answer:
CH4<HClO2<HClO<H2O<HCl
Explanation:
In ranking the compounds on the basis of increasing positive charge of hydrogen, we must consider the relative oxidation numbers of the various elements in the compounds.
Methane contains a nonpolar covalent bond, HClO2 contains a chlorine atom in +3 oxidation state, HClO contains a chlorine atom in +1 oxidation state. The more the positive charge on the halogen atom the lesser the magnitude of positive charge on the hydrogen atom. Between water and HCl, chlorine is more electro negative hence HCl will contain a more positively charged hydrogen atom than water.
B. The moon
Tides are due to the gravitational forces of the Moon and the Sun. The tide is high when the moon or the sun or both are on the side of the sea and vice versa.
The effect of tides due to the moon is much greater than that of the sun, because the moon is much closer to the earth.
The answer to this question is 2 and 3
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
Dalton based his theory on the law of conservation of mass and the law of constant composition.
The first part of his theory states that all matter is made of atoms, which are indivisible.
The second part of the theory says all atoms of a given element are identical in mass and properties.
The third part says compounds are combinations of two or more different types of atoms.
The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.
Parts of the theory had to be modified based on the discovery of subatomic particles and isotopes.
The masses of the liquids are different making them have different densities
