There are 1000 students in a school. They have to stand in such a way that the number of rows are equal to the number of columns. How many students would be left out in this arrangement?
24
39
64
100
So, the nearest natural number will be the row number. Hence number of students can be filled in these rows and columns are . So, we can check that number of students left out will be . Hence 39 will be the required answer.

Brine is electrolyzed using graphite electrode
Molten sodium chloride is used
Sodium amalgam is formed at mercury cathode
Brine is electrolyzed with Pt electrodes
In a constant volume calorimeter, 3.5 g of a gas with molecular weight 28 was burnt in excess of oxygen at 298 k. The temperature of the calorimeter was found to Increase from 298 k to 298.45 k due to the combustion process. Given that the heat capacity of the calorimeter is 2.5 KJ/K. The Numerical value for the enthalpy of combustion of the Gas in KJ /Mole is
