If magnesium atom having atomic number $12$ has an isotope with mass number $26$, then the number of protons, neutrons and electrons respectively of the atom are
If a cyclist moving with a speed of $4.9\, m / s$ on a level road can take a sharp circular turn of radius $4 \,m$, then coefficient of friction between the cycle tyres and road is
If $300\,mL$ of a gas at $27^{\circ} C$ is cooled to $7^{\circ} C$ at constant pressure, its final volume will be
How many significant figures are there in $30.00$ ?
Ficus is an example of which kind of inflorescence?
Epiphytic roots absorb moisture from atmosphere directly due to presence of
Dimensions $\left[ ML ^{-1} T ^{-1}\right]$ are related to
$CuSO_4$ reacts with $KCN$ solution and forms
Cumulus covers
Zinc displaces copper from copper sulphate solution. The $E^{\circ}_{298\, K}$ of $Zn$ is $-0.76 \,V$ and that of $Cu$ is $+0.34 \,V$.
The stem tubers are the swollen ends of specialised underground stem branches, which help in vegetative propagation of the plant. Solanum tuberosum is an example of a root tuber which stores inulin as the main reserve food material.
Tailing of mercury occurs on passing ozone through it. Due to oxidation of mercury.
Only a change in magnetic flux will maintain an induced current in the coil. The presence of large magnetic flux through a coil maintains a current in the coil if the circuit is continuous.
On a rainy day, it is difficult to drive a car or bus at high speed. The value of coefficient of friction is lowered due to wetting of the surface.
Lower aldehydes and ketones are soluble in water but the solubility decreases as the molecular masses increase. Distinction between aldehydes and ketones can be made by Tollens??test.
Isotopes of an element can be separated by using a mass spectrometer. Separation of isotopes is possible because of the difference in electron numbers of isotopes.
It is the brain, not the sense organs, that interprets the stimulus. Sense organs are transducers. They transform the energy of a stimulus to the energy of nerve impulses.
Pressure in a mixture of $4 \,g$ of $O _{2}$ and $2\, g$ of $H _{2}$ confined in a bulb of 1 litre at $0^{\circ} C$ is
Which of the following are ${ }_{16} S ^{32}$ and ${ }_{15} Pb ^{31}$ ?
Which of the following transition elements shows the highest oxidation state?
Which of the following has maximum ionisation potential?
The solubility in water of sulphates down the $Be$ group is $Be > Mg > Ca > Sr > Ba$. This is due to
Oxidation state of osmium (Os) in $OsO_4$ is
Which of the following is the correct statement for $PH_3$ ?
Which of the following will not undergo hydrolysis in water?
