This reaction is known as
Acidic Cleavage of Ether.
Ether when treated with strong acid like
HI, the oxygen atom of ether picks the proton making a positive charge on oxygen. The
Iodide conjugate base formed acts as a
nucleophile and attacks on the carbon next to positive oxygen and forms
Alkyl Halide. This is a type of
SN² reaction. The complete reaction with missing atoms, charges and arrows is shown below,
Organisms change their behavior in responses to changes in the environment.
All living things can respond to stimuli in the exterior environment, it is a form of energy-light waves or sound vibrations, From what they sense they will make necessary changes to their diet and or where they are located. Such as winter weather which is a type stimuli will cause some animals to start talking.
Answer:
3) The amount of matter within the system remains the same
5) The cycle has a well-defined starting and stopping point.
Explanation:
A closed system is a system that the boundaries of a system cannot be passed by either matter or energy.
Hence, generalisations can be made based on a closed system and the law of conservation of mass which states that matter can neither be created nor destroyed but can only change form.
Answer:
28 g solute per 100 g of solution
Explanation:
28% mass means that in all your solution you have 28% of your solute, you could use grames/grames, ml/ml or whatever you want to. So if you are working with a 100 grams solution, 28 grams of that solution must be solute if you want a 28% mass. So, the correct answer is 28 g solute per 100 g of solution.
Answer:
The periodic law states “When elements are arranged in order of increasing atomic number, there is a periodic repetition of their chemical and physical properties
