Answer: Covalent
Explanation:
A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals. Example:
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal. Example:
Thus bond formed by sharing of electrons is covalent bond.

Answer: non metal
Explanation:
Nonmetals are dull, possess high ionization energies and electronegatives and are typically poor electricity conductors as they're insulators.
Non metals are also brittle and possess low melting point. Therefore, with the explanation, the sample is most likely a non metal.
The sample described is most likely a sulfur solid.
The sample described in the question, which is pale yellow, brittle, and has no shine, is most likely a sulfur solid. Sulfur is a chemical element that is commonly found in its solid form and has a pale yellow color. It is brittle, meaning that it shatters easily upon impact, and it does not have the characteristic shine that metals have.

Answer:
0.0798 mol Mg
Explanation:
a) divide the number of grams of magnesium by the molar mass of magnesium found on the periodic table
1.94g Mg/(24.31g Mg/mol Mg)=0.0798 mol Mg
Water molecules are carried into n-butanol.
n-Butanol molecules surround water molecules.
n-Butanol molecules are attracted to the surface of the water molecules.
Water is dissolved into n-butanol (a polar liquid). The second step at the molecular level as water dissolves into n-butanol is n-Butanol molecules surround water molecules.
Dissolving is a process of fully mixing of the solute into a solvent. When there molecules of solute and the molecules of solvent mixed and there is no difference between them.
Thus, the correct option is C, n-Butanol molecules surround water molecules.
