In crystalline solid, atoms, ions or molecules are held in an orderly array. But some point defect is observed in a crystal, when a vacancy is created by an atom or ion dislocated from its normal position to an interstitial site. What is the defect called?

Diagunabisable the matrix \( A=\left[\begin{array}{ccc}8 & -8 & -2 \\ 4 & -3 & -2 \\ 3 & -4 & 1\end{array}\right] \) and find \( A^{4} \)

A = \(\begin{bmatrix}8&-8&-2\\4&-3&-2\\3&-4&1\end{bmatrix}\)  A2 = \(\begin{bmatrix}8&-8&-2\\4&-3&-2\\3&-4&1\end{bmatrix}\)\(\begin{bmatrix}8&-8&-2\\4&-3&-2\\3&-4&1\end{bmatrix}\) = \(\begin{bmatrix}26&-32&-2\\14&-15&-4\\11&-16&3\end{bmatrix}\) A4 = A2. A2 = \(\begin{bmatrix}26&-32&-2\\14&-15&-4\\11&-16&3\end{bmatrix}\)\(\begin{bmatrix}26&-32&-2\\14&-15&-4\\11&-16&3\end{bmatrix}\) = \(\begin{bmatrix}206&-320&-70\\110&-159&20\\95&-160&51\end{bmatrix}\)

Why dispersion of light is not observed in glass slab but it is observed in prism?

When a light passes from one medium to another, at one interface, it changes its speed. The glass slab and prism both have two glass air interfaces. Hence, the light undergoes refraction...

Find the Inverse?\[A=\left[\begin{array}{lll}2 & 1 & 1 \\3 & 2 & 1 \\2 & 1 & 2\end{array}\right] \quad A^{-1}=?\]

We have A = IA \(\begin{bmatrix}2&1&1\\3&2&1\\2&1&2\end{bmatrix}=\) \(\begin{bmatrix}1&0&0\\0&1&0\\0&0&1\end{bmatrix}\)A Applying R3 → R3 — R1 R2 → 2R2 — 3R1 \(\begin{bmatrix}2&1&1\\0&1&-1\\0&0&1\end{bmatrix}=\)\(\begin{bmatrix}1&0&0\\-3&2&0\\-1&0&1\end{bmatrix}\)A Applying R2 → R2 + R3 \(\begin{bmatrix}2&1&1\\0&1&0\\0&0&1\end{bmatrix}=\)\(\begin{bmatrix}1&0&0\\-4&2&1\\-1&0&1\end{bmatrix}\)A Applying R1 → R1 — R2 — R3 \(\begin{bmatrix}2&0&0\\0&1&0\\0&0&1\end{bmatrix}=\) \(\begin{bmatrix}6&-2&-2\\-4&2&1\\-1&0&1\end{bmatrix}\)A Applying R1 → \(\frac{R_1}2\) \(\begin{bmatrix}1&0&0\\0&1&0\\0&0&1\end{bmatrix}=\)\(\begin{bmatrix}3&-1&-1\\-4&2&1\\-1&0&1\end{bmatrix}\)A Hence A-1 = \(\begin{bmatrix}3&-1&-1\\-4&2&1\\-1&0&1\end{bmatrix}\)

Equimolar mixture of two gases \( A_{2} \) and \( B_{2} \) is taken in a rigid vessel at temperature \( 300 K \). The gases reacts according to given equations : \[ \begin{array}{ll} A_{2}(g) \rightleftharpoons 2 A(g) & K_{P_{1}}=? \\ B_{2}(g) \rightleftharpoons & K_{P_{2}}=? \\ A_{2}(g)+B_{2}(g) & \rightleftharpoons 2 A B(g) & K_{P_{3}}=2 \end{array} \] If the initial pressure in the container was 2 atm and final pressure developed at equilibrium is \( 2.75 atm \). in which equilibrium partial pressure of gas \( A B \) was \( 0.5 atm \), calculate the ratio of \( \frac{ K _{ p _{2}}}{ K _{ p _{1}}} \). [Given : Degree of dissociation of \( B_{2} \) is greateı than \( A _{2} \) ].

this is the solution!!!!

Identify the odd one out and justify. Crystalline blue vitriol, crystalline common salt, crystalline ferrous sulphate, crystalline sodium carbonate.

Crystalline common salt is the odd one out, as it does not contain water of crystallisation. It is an ionic compound and ionic compounds are crystalline in nature and rest all...
