The following statements concern elements in the periodic table. Which of the following is true?
The bond angle H-X-H is the greatest in the compound:
Initially, the root-mean-square (RMS) velocity of $$N_2$$ molecules at certain temperature is u. If this temperature is doubled and all the nitrogen molecules dissociate into nitrogen atoms, then the new RMS velocity will be:
If 100 mole of $$H_2O_2$$ decompose at 1 bar and 300 K, the work is done (kJ) by one mole of $$O_2(g)$$ as it expands against 1 bar pressure is:
