How Flame Test Colors Are Produced - ThoughtCo
21/2/2020· Calcium The noble metals gold, silver, platinum, palladium, and some other elements do not produce a characteristic flame test color. There are several possible explanations for this, one being that the thermal energy isn''t sufficient to excite the electrons of these elements enough to release energy in the visible range.

Flame Test Lab - Aidan Sterk''s Digital Portfolio
By placing atoms of a metal into a flame, electrons can be induced to absorb energy and jump to an excited energy state, a quantum jump. They then return to their ground state by emitting a photon of light (the law of conservation of energy indies that the photon emitted will contain the same amount of energy as that absorbed in the quantum jump).

What happens when zinc react with water. answer with equation - 5631051 Zinc does not react directly with water.It depends on the temperature of both, the zinc metal as well as the water. Under normal conditions, zinc does not react with water.
What precipitate will form when aqueous solutions of …
The precipitate that would form when mixing aqueous solutions of sodium carbonate (na2co3) and calcium chloride (cacl2) would most likely be calcium carbonate (CaCO3). Mixing sodium carbonate and calcium chloride would result to a double replacement reaction or metathesis reaction forming two salts namely sodium chloride and calcium carbonate.

Melting Point | Chemistry for Non-Majors - Lumen Learning
Melting Point Solids are similar to liquids in that both are condensed states, with particles that are far closer together than those of a gas. However, while liquids are fluid, solids are not. The particles of most solids are packed tightly together in an orderly
Hard water - Wikipedia
Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.
