Alkenes on reaction with meta-chloroperoxybenzoic acid (MCPBA ) produces epoxides. When styrene is reacted with mCPBA it gives 2-phenyloxirane as shown below,
It is exothermic. Exothermic reaction is a reaction that gives out heat and energy. Sodium is a highly reactive metal that is found in group 1 in the periodic table. We all know that all group 1 elements(alkali metals) are usually stored in inert liquid like oil to prevent contact with air and water so as to prevent an explosion. An explosion is a form of a exothermic reaction since it gives out heat and light. Hence, the reaction between Na and water is an exothermic reaction.
Have a nice day ahead.
Answer
C. Difference in temperature
Explanation
According to thermodynamics, heat transfer occurs when heat from a high temperature reservoir moves to a low temperature reservoir. For heat to be transferred, the two objects should have different temperatures with one having more temperature than the other. Heat transfer in solids is by conduction, in fluids is by convection and by radiation.
Secrets undiscovered is correct, but this chemical formula is not balanced. Double check your question to make sure
As we know that <span>Boron has 6 valence electrons
So it does not have to fill a complete octet. it just need two electrons
Thus B(CH3)3 will have only 3 electron domains, and it will constitute</span> a trigonal structure.
