Explanation

The chemical formula for tetrafluoroethylene is C₂F₄.

Key points about Teflon:

Chemical name: Polytetrafluoroethylene (PTFE)

Monomer: Tetrafluoroethylene

Notable property: Highly non-stick surface, often used in cooking utensils

Explanation

Photosynthesis occurs most efficiently in this temperature range, as enzymes involved in the process function optimally.

Temperatures above 35°C can inhibit enzyme activity, reducing the rate of photosynthesis.

Explanation

The carbon dioxide (CO₂) molecule has a linear structure, with a bond angle of 180°.

Due to the two double bonds between carbon and oxygen atoms.

Explanation

"Everyone" is an indefinite pronoun as it refers to a non-specific group of people.

It does not point to any particular individual but refers collectively to all people.

Explanation

An element with 7 valence electrons needs 1 more electron to complete its octet.

Therefore, its valency is 1, as it tends to gain 1 electron during bonding.

Explanation

Cobalt-60, an isotope of cobalt, is widely used in radiation therapy to treat cancer.

It emits gamma rays, which help destroy cancerous cells in medical treatments.

Explanation

Carbon has 4 electrons in its outer shell.

It forms 4 covalent bonds, making it tetravalent (valency = 4).

Explanation

SOLO Taxonomy consists of five levels:
