Argon was discovered by Lord Rayleigh and Sir William Ramsay in 1894. It was isolated by examination of the residue obtained by removing nitrogen, oxygen, carbon dioxide, and water from clean air.
Dry, white powder, soluble in water to form a slightly basic solution
Answer:
a chain of decays that result in a stable nucleus
Explanation:
Decay series is a series of decay in which radioactive element is decomposed in different elements until it produces one stable atom.
The answer is 1. CO. A gram-molecular mass is defined as mass in grams numerically equal to the molecular weight of a substance or the sum of all the atomic masses in its molecular formula. Since CO2 and CO has both carbon and oxygen, the gram-molecular mass does not change. For a compound with carbon and oxygen, the molecular mass comes respectively from 12 (atomic mass of carbon) + (2 × 16) (atomic mass of oxygen), which is 44 g.
Answer: as a relatively high boiling point high specific heat connotation adhesion and density
Explanation:
water molecules are polar so they form hydrogen bonds this gives water unique properties
