Matter that does not enter chemical reactions is described as this... A: Inhibited, B: Inert, C: Grounded, D: Radioactive
What is B: Inert. Inert matter does not enter chemical reactions.

This is the hardest naturally occurring substance... A: emerald B: tourmaline C: diamond D: corrundum
What is C: Diamond. Diamond is also one of the most valuable natural substances. Diamonds are crystals formed almost entirely of carbon. Because of its hardness, the diamond is the most enduring of all gemstones. They are among the most costly jewels in the world, partly because they are rare, Only four important diamond fields have been found - in Africa, South America, India, and the Soviet Union.

These are microscopic spheres of 60 atoms of pure carbon in a spherelike structure that resembles a geodesic dome... A: Hydrocarbons, B: Lipids, C: Crystals, D: Buckyballs
What is D: Buckyballs. "Buckyballs" are microscopic spheres of 60 atoms of pure carbon in a spherelike structure that resembles a geodosic dome. Also called fullerenes or buckminsterfullerenes, they were named after R. Buckminster Fuller who invented the geodosic dome. Buckyballs are of great interest to scientists because they contain a cavity large enough to hold other elements, even whole molecules. Once an element has been deposited into the cavity, it cannot emerge without being heated to high temperatures. This technology may someday be used to deliver medication to specific locations within the body.

The first Earth Day was celebrated in this year... A: 1950 B: 1960 C: 1970 D: 1980
What is C: 1970. The first Earth Day was celebrated on April 22, 1970, and has been celebrated each year following on April 22nd. The original purpose of Earth Day was to inspire people to think and act more environmentally. Earth Day falls on or around the birthdays of several environmental spokespersons.
