Answer:
CH3+
Explanation:
Sp2 hybridization involves the mixing of on s and two p orbitals. This is observed in CH3+. The ion is trigonal planar with a H-C-H bond angle of 120°.
The anion, CH3^- is sp3 hybridized, hence only CH3+ is sp2 hybridized among the options.
Answer: Y is Hydrogen.
Explanation: Based on the valence electrons, X and Y are Group 1 Elements and Y is a Halogen. Based on the differences between X and Y and the similarities between Y and Z, we can say that Y is Hydrogen, the only nonmetal with 1 valence electron. This is based on the fact that it has typical nonmetal characteristics: low melting and boiling points.
Sugar is a compound because sugar is composed of carbon, hydrogen, and oxygen elements. (C12H22O11)
Under conditions of very high pressures, the volume would be lower than predicted by the Ideal Gas Law.
According to the kinetic theory of gases, a gas spreads out to fill the volume of the container holding it. Hence a gas does not have a definite volume due to the fact that there is no inter-molecular interaction between gas molecules.
When the gas is subjected to very high pressure, inter-molecular interactions become significant leading to a decrease in the volume of the gas.
Therefore, when subjected to high pressure, the experimental volume would be lower than predicted by the Ideal Gas Law.
