The Bragg’s equation is

How Bragg’s equation is used for determining crystal structure.

In the Bragg’s equation for diffraction of X-rays,’n’ represents

Consider the reaction CI_(2) (aq)+H_(2)S(aq) rarr S(s)+2H^(+)(aq) +2CI^(-1)(aq) The rate equation for this reaction is rate = k[CI_(2)] [H_(2)S] Which of these mechanisms is /are consistent with this rate equation ? CI_(2)+H_(2)S rarr H^(+)+CI^(-)+CI^(+)HS^(-) (slow ) CI^(+)+HS^(-)+CI^(-)+S (fas) H_(2)S rarr H^(+)+HS^(-) (fast equilibrium ) CI_(2)+HS^(-) rarr 2CI^(-)+H^(+) +S (slow )

Write Einsten.s photoelectric equation and point out any two characteristic properties of photons on which this equation is based.

Derive de-Broglie’s equation. What is its significance?

The roots of an equation are +2 and -2 ,then the equations is a/an:

Write the Nernst equation for the half cell Zn_((aq))^(2+)//Zn_((s)).

Check the correctness of the equations, (i) s = ut + 1//2 at ^ 2 and (ii) s _ (nth) = u + (a)/(2) ( 2 n - 1 )

Let r ,s and t be the roots of equation 8x^3+1001 x+2008=0. Then find the value of (r+s)^3 +(s+t)^3+(t+r)^3 .
