Answer:
Explanation:
Because of the acid-base reaction, as sodium bicarbonate is introduced to the separatory funnel, the additional or unreacted HBr reacts vigorously to yield CO2 gas, which exits the separatory funnel together with any dissolved compound(s) in the ether layer. This is due to a wrong and incorrect selection of the solvent mixture and the addition of sodium bicarbonate to an acidic solution.
Nothing to do with it until it has leaked out of the separatory funnel. Even then, the student may separate the components from the remaining reaction mixture by washing the ether coating layer several times with brine water, then running it into a dry sodium sulfate bed and evaporating solvent ether under decreased pressure.
Answer:
I believe the answer is D
The Physical properties of Iron are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.
Explanation:
Color Silver-gray metal
Malleability Capable of being shaped or bent
Ductility Easily pulled or stretched into a thin wire
Luster Has a shine or glow
Conductivity Good transmission of heat or electricity
Allotropy It occurs in two or more crystalline forms in the same physical state
Tensile It can be stretched without breaking
Ferromagnetic Easily magnetized
Answer: H2o
Explanation:
because oxygen is in the air
There are many examples of lower vertebrates that hibernate in temperature regions where ice growth in the extracellular fluid is tolerated within certain limits. For example, the wood frog, Rana sylvatica, is capable of withstanding temperatures as low as -8°C, with 65% of its body water converted to ice, or at temperatures of -2.5°C for periods of up to 2 weeks.
