When glucose reacts with bromine water,the main product is:

For all integers $n \geq 1$, which of the following is divisible by $9$?

In the following circuit,$PN$-junction diodes $D_1, D_2,$ and $D_3$ are ideal. For the following potentials of $A$ and $B$:
$(i) -10 \ V, -5 \ V$
$(ii) -5 \ V, -10 \ V$
$(iii) -4 \ V, -12 \ V$
The correct increasing order of resistance between $A$ and $B$ will be:

The enthalpy change $\left( \Delta H \right)$ for the reaction,$N_{2(g)} + 3H_{2(g)} \to 2NH_{3(g)}$ is $-92.38 \ kJ$ at $298 \ K$. The internal energy change $\left( \Delta U \right)$ at $298 \ K$ is ........ $kJ$.

The value of $\lambda$ with $|\lambda| < 16$ such that $2 x^2-10 x y+12 y^2+5 x+\lambda y-3=0$ represents a pair of straight lines,is
