What is phase diagram classify phase diagram?
Phase diagram is a graphical representation of all the equilibrium phases as a function of temperature, pressure, and composition. For one component systems, the equilibrium state of the system is defined by two independent parameters (P and T), (T and V), or (P and V).
Would you characterize the solid phase of bromine as more dense or less dense than the liquid phase of bromine?
Solid bromine is denser than liquid bonine. (6) Using arrows labeled ‘S’, ‘V’, and ‘M’, label those portions of the phase diagram where sublimation, vaporization, and melting occur, respectively.
What is the difference between bromine and bromide?
Bromine is a chemical element of the halogen group, which includes fluorine, chlorine, iodine and astatine. Bromide is an anion of bromine, commonly found in trace amounts as salt in sea-water, along with sodium chloride (common table salt).
What does bromine look like?
Bromine is a naturally occurring element that is a liquid at room temperature. It has a brownish-red color with a bleach-like odor, and it dissolves in water.
How do you know which phase is more dense on a phase diagram?
The solid phase is more dense than the liquid phase. The line that separates solid and liquids bends right. IF the solid phase is less dense than the liquid phase. The line that separates solid and liquids bends left.
How do you know if a phase diagram is more dense?
To be sure, look at the slope of the solid-liquid line. If it is decreasing, the liquid phase is denser, if it is increasing, the solid phase is denser. For example, the phase diagram of water has a negative solid-liquid line; the liquid phase of water is denser.
What is the difference between chlorine and bromine?
Chlorine works faster to kill contaminants but for a shorter period of time, as it dissipates faster. Bromine kills contaminants more slowly but for a longer period of time; plus, it can help keep water chemistry more balanced due to its low pH, meaning less chemical adjusting is needed.
What does chlorine look like?
Chlorine is yellowy-green in colour, as is the image. A yellowy-green dense gas with a choking smell. Chlorine kills bacteria – it is a disinfectant. It is used to treat drinking water and swimming pool water.
Which is better bromine or chlorine?
If you have a spa, bromine has a lot of advantages over using chlorine. It may cost a little bit more, but it lasts longer and does a much better job than chlorine at killing bacteria, especially at high temperatures and high pH levels.
What is 3phase diagram?
The diagrammatic representation of different phases seperated in soil mass is called phase diagram. A partially saturated soil, which voids are partially filled with water and air, contains three phases viz solid, water and air. Hence it is called 3 phase Diagram.
What is the difference between bromine and chlorine?
The main difference between bromine and chlorine is that bromine is a reddish-brown liquid. Meanwhile, chlorine is a greenish-yellow gas in a normal state. Secondly, Bromine is number 35 in the periodic table, while chlorine is number 17 in the periodic table.
What is the difference between bromination and chlorination?
The relative reaction rate of bromination for different radical is shown here, and you can see the big difference to that of chlorination: For bromination, the reactivity difference between different types of position is so high that the reactivity factor become predominant for determining the product.
Why does bromine show greater selectivity than other hydrocarbons?
The relative lower reactivity of bromine makes it exhibits a much greater selectivity. Bromine is less reactive, means it reactive more slowly, therefore it has chance to differentiate between the different types of hydrogens, and selectively reacts with the most reactive one.
How to predict the amount of chlorination product in Monochlorination of propane?
The experimental results of the monochlorination of propane indicate that 45% primary chloride (1-chloropropane) and 55% secondary chloride (2-chloropropane) are produced. How to explain this result? To predict the relative amount of different chlorination product, we need to consider two factors at the same time: reactivity and probability.
