<h3>How are elements named?</h3>

Elements have been given names based on a variety of factors, including their characteristics, the compound or ore from which they were extracted, the method by which they were found or acquired, mythical characters, locations, and well-known individuals. Some components have names that are descriptive and are based on one of their attributes.

The International Union of Pure and Applied Chemistry chooses the official element names and symbols (IUPAC). However, different nations frequently use similar names and symbols for elements. Official names and symbols for elements are not given until after their discovery has been confirmed. The discoverer may then suggest a name and a symbol.

There are name standards for several element groupings. Names of halogens end in -ine. All noble gas names, save helium, end in -on. The names of most other elements finish with -ium.

Why do we need to use moles when we try to determine amounts of reactants and products in a reaction?.

ICE Princess25 [194]

$\huge\fbox{Answer ☘}$

Chemists use the mole unit to represent 6.022 × 10 23 things, whether the things are atoms of elements or molecules of compounds. This number, called Avogadro's number, is important because this number of atoms or molecules has the same mass in grams as one atom or molecule has in atomic mass units.

Antarctica, almost completely covered in ice, has an area

Marysya12 [62]

Answer: The mass of ice is $2.39\times 10^{22}g$

Explanation:

We are given:

Area of Antarctica = $5,500,000mi^2=5,500,000\times 2.59\times 10^{10}=142.45\times 10^{15}cm^2$ (Conversion factor: $1mi^2=2.59\times 10^{10}cm^2$ )

Height of Antarctica with ice = 7500 ft.

Height of Antarctica without ice = 1500 ft.

Height of ice = 7500 - 1500 = 6000 ft = $182.88\times 10^3cm$ (Conversion factor: 1 ft = 30.48 cm)

To calculate mass of ice, we use the equation:

$\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}$

We are given:

Density of ice = $0.917g/cm^3$

Volume of ice = Area × Height of ice = $142.45\times 10^{15}cm^2\times 182.88\times 10^3cm=26051.26\times 10^{18}cm^3$

Putting values in above equation, we get:

$0.917g/cm^3=\frac{\text{Mass of ice}}{26051.26\times 10^{18}cm^3}\\\\\text{Mass of ice}=(0.917g/cm^3\times 26051.26\times 10^{18}cm^3=2.39\times 10^{22}g$

Hence, the mass of ice is $2.39\times 10^{22}g$
