I believe it is:
CH4
Ar
Cl2
CH2COOH
I hope this helps :)
Answer:
C. Reducing the air pressure allows the molecules to escape.
Explanation:
Lower air pressure can be found in the mountain or any high ground place. In this place, you will need less temperature to boil water or other liquid.
A liquid phase will change into gas when it reaches the vapor pressure of the surrounding air. At that point, the molecule can move freely as the gas phase. Since the atmospheric pressure is preventing the liquid to become gas, if the pressure is lower, the liquid can boil at a lower temperatures.
<span>The answer to the question is the release of energy. The bonds that bind a molecules atom's act as a storage of energy. One way it is released is when those bonds are broken and it is released outward in every direction. This breakage results in smaller molecules and not the formation of a larger molecule.</span>
The correct answer is C. square planar
According to the Valence Shell Electron Pair Repulsion Theory(VSEPR), The shape of a molecule depends on the number of electron pairs in the molecule.
VSEPR theory was first coined by Gillespie and Nyhlom in 1957 as an improvement over the Sidgwick - Powell theory.
According to this theory, the shape of a molecule is determined by the number of electron pairs that surround the valence shell of the central atom in the molecule. The electron pairs are positioned as far apart in space as possible to minimize repulsion of electron pairs.
However, the presence of lone pairs distorts the shape anticipated for the molecule on the basis of VSEPR.
For a molecule having six electron pairs, an octahedral geometry is expected(electron domain geometry). However, the presence of two lone pairs which are positioned at opposite side of the four single bonds leads to an observed square planar molecular geometry.

Answer:E. NH3 and CH3OH
Explanation:
NH3 and CH3OH are soluble in water and would give an homogenous solution.
A homogeneous solution is a type of solution with uniform properties and compositional proportion throughout the solution.
