Answer:
a number of people or things that are located close together or are considered or classed together.
Explanation:
Answer:
In pure water, at 25C, the [H3O+] and [OH-] ion concentrations are 1.0 x 10-7 M. The value of Kw at 25C is therefore 1.0 x 10-14. Although Kw is defined in terms of the dissociation of water, this equilibrium constant expression is equally valid for solutions of acids and bases dissolved in water.
Explanation:
Explanation:
HCl(aq)+ NaOH(aq)→NaCl(aq)+H2O(l) ..
Following reaction shows the preparation of
Nitrile from
Amide. In this reaction
Thionyl Chloride (SOCl₂)is reacted with Amide, which produced nitrile along with
SO₂ and
HCl gas. The
importance of this reaction is the removal of byproducts (i.e SO₂ and HCl). As both SO₂ and HCl are
gases so no extra workup is required to remove them. The
mechanism of reaction is as follow,
Answer:
Option A an E.
Explanation:
Energy can be described as the capability to do work. It is what has to be transferred to an object in order to get this object to do work. Energy can be in various forms such as heat energy, kinetic, potential, electrical, chemical, nuclear etc.
It takes energy to do quite a number of things, from cooking food to driving and also in engaging in exercises.
