Answer is: increase the concentration of NiCO₄ and <span>withdraw CO from the products as it is forming.
Balanced chemical reaction: NiCO</span>₄(g) ⇄ Ni(s) + 4CO(g).
According to Le Chatelier's Principle the position of equilibrium
moves to counteract the change:
1) the position of equilibrium will move to the right, so
that the concentration of nickel carbonyl gas decreases again and produce more nickel.
2) the position of equilibrium will move to the right, if we decrease concentration of carbon monoxide, more nickel carbonyl gas will decompose and produce more nickel.
1/3 fraction of the original uranium-235 should be left after 3.5 billion years
The only naturally occurring isotope of this radioactive metal, uranium-235, is capable of supporting a nuclear fission reaction, making it special. A variation of an element called an isotope has a different number of neutrons in its nucleus. Approximately 93.5 percent of the uranium used in modern nuclear bombs is enriched.
On average, plutonium-239 makes up 93% or more of nuclear bombs, whereas plutonium-240 makes up less than 7% and other plutonium isotopes are present in extremely minute amounts. A nuclear bomb requires around 33 pounds (15 kilograms) of enriched uranium to function, according to the Union of Concerned Scientists.

Answer:
Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms; the genes they contain; and the ecosystems they form on land and in water. ... It is increased by new genetic variation and reduced by extinction and habitat degradation
I think the answer is : they are molecules not element
