Answer 1

There be none of Beauty»s daughters
With a magic like Thee;
And like music on the waters
Is thy sweet voice to me:

Answer 2

Characteristics of C2H4:

C2H4 is the chemical formula for ethylene, which is a colorless, flammable gas with a sweet odor. It is the simplest alkene and is widely used in the chemical industry for the production of various plastics and synthetic materials.

Formula of the Compound:

If a molecule contains 2 atoms of nitrogen and 5 atoms of oxygen, the compound's formula can be determined as follows: - The compound contains 2 nitrogen atoms, which corresponds to the element N. - The compound contains 5 oxygen atoms, which corresponds to the element O. - Therefore, the formula of the compound is N2O5.

Forms of Fluorine:

Each of the following notations indicates a different form of existence for the chemical element fluorine: 1. 2F: This notation represents the diatomic molecule of fluorine, where two fluorine atoms are bonded together to form a molecule of F2. 2. 3F2: This notation indicates the existence of three molecules of diatomic fluorine, F2. 3. OF2: This notation represents the compound oxygen difluoride, which consists of one oxygen atom and two fluorine atoms bonded together.

Fluorine is a highly reactive, pale yellow diatomic gas at standard conditions. It is the most electronegative element and is widely used in various industrial and chemical applications.
