Provide an explanation at the subatomic level to explain why different colors are observed for different metal salts.
lakkis [162]

Answer:

When you heat an atom, some of its electrons are "excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. ... The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.

aivan3 [116]
<span>100 g of KClO3 @ 122.55 g/mol = 0.816 moles of KClO3
   by the reaction
 2 KClO3 --> 2 KCl & 3 O2

   0.816 moles of KClO3 @ 3 moles O2 / 2 moles KClO3 = 1.224 moles of O2 can be made using molar mass
 1.224 moles of O2 @ 32.0 g/mol =

Choose the most appropriate reagent(s) for the conversion of propyne and 2-methyl-1-tosyloxypropane to 5-methyl-2-hexyne. NaNH2,
Yuki888 [10]

Answer:

NaNH2, NH3

Explanation:

Choose the most appropriate reagent(s) for the conversion of propyne and 2-methyl-1-tosyloxy propane to 5-methyl-2-hexyne. NaNH2, NH3 NaOH, H2O KOCH2CH3, HOCH2CH3 H2SO4 NH3

answer is  NaNH2, NH3

NaNH2, NH3 is strong to to convert propyne into a nucleophilic salt which in turn displaced tosylate in  2-methyl-1-tosyloxy propane to yield  5-methyl-2-hexyne.

Propyne and 5-methyl-2-hexyne. are still of the same homologous series,, so no triple bond is broken during the reaction

The essence of a reagent is to bring the reaction to its end point

Natural gas is a mixture of many substances, primarily CH₄, C₂H₆, C3H8, and C4₄H₁₀. assuming that the total pressure of the gase
olchik [2.2K]

Answer:

A. The partial pressure for CH4 = 0.0925atm

B. The partial pressure for C2H6 = 0.925atm

C. The partial pressure for C3H8 = 0.346atm

D. The partial pressure for C4H10 = 0.115atm

Explanation:

Total pressure = 1.48atm

Total mole = 0.4+4+1.5+0.5=6.4

A. Mole fraction of CH4 = 0.4/6.4 = 0.0625

The partial pressure for CH4 = 0.0625 x 1.48 = 0.0925atm

B. Mole fraction of C2H6 = 4/6.4 = 0.625

The partial pressure for C2H6 = 0.625 x 1.48 = 0.925atm

C. Mole fraction of C3H8 = 1.5/6.4 = 0.234

The partial pressure for C3H8 = 0.234 x 1.48 = 0.346atm

D. Mole fraction of C4H10 = 0.5/6.4 = 0.078

The partial pressure for C4H10 = 0.078 x 1.48 = 0.115atm
