<span>People with anxiety disorders frequently have intense, excessive and persistent worry and fear about everyday situations. Often, anxiety disorders involve repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes (panic attacks). </span>
If it is an ionic bond (metal with nonmetal) the electrons will be transferred. If it is a covalent bond (nonmetal with nonmetal) the electrons will be shared. It depends on the electronegativities; the closer the electronegativities of the two atoms, the more covalent the bond is, making the electrons more equally shared. But if the electronegativities are very different, one atom (the nonmetal) will pull the electrons from the other (the metal).

<span>Along with operating the instruments, Beer's law also involves calculations to actually figure out the concentration of a solution from the absorbance measurements made by using the colorimeter (or spectrophotometer). There are three methods that can be used depending on what information is available. They involve using proportionality, graphing and Beer's Law.
hope this helps</span></span>
i do not know what that is sorry
