Explanation

 At a safe distance park in a hazardous chemical incident

Explanation

The first evidence of helium was observed on August 18, 1868

 as a bright yellow line with a wavelength of 587.49-nanometers in the spectrum of the chromosphere of the Sun.

The line was detected by French astronomer Jules Janssen during a total solar eclipse in Guntur, India.

Explanation

Every living thing is made up mostly of water. Water is the most abundant substance in living organisms, making up approximately:

- 55-60% of an adult human's body weight

- 70-80% of a plant's weight

- 70-90% of an animal's weight

Water is essential for many biological processes, including:

- Regulating body temperature

- Transporting nutrients and oxygen

- Removing waste products

- Maintaining cell shape and structure

Water is truly the foundation of life!

Explanation

Elements can be classified as metals, metalloids, and nonmetals.

Explanation

Bauxite is the most common aluminum ore. Approximately 98% of primary aluminum production is based on bauxite

Explanation

Light Emitting Diodes are light sources that are energy efficient and can be made in a variety of colors.

Gallium is a soft, silvery metal used primarily in electronic

circuits, semiconductors, and light-emitting diodes (LEDs).

LEDs are comprised of compound semiconductor materials, which are made up of elements from group III and group V of the periodic table
