The mass of 254 mL of water is 254 g. Since the density of water is 1g/mL, we can simply multiply the density 1g/mL by 254 mL of water and get 254 g as our answer. Since mL is in the numerator and denominator, mL cancels out and we are left with g only.
A nitrogen atoms can make 3 covalent bonds because it has three unpaired electrons
freezing-energy lost (exothermic)
sublimation-energy gain (endothermic)
evaporation- energy gain(endothermic)
Melting- energy gain(endothermic)
deposition- energy lost(exothermic)
condensation-energy lost(exothermic)
Answer:
two hydrogen can bonded with oxygen to form H2O
Answer:
Option-B (water) is the correct answer.
Explanation:
Gas hydrates are made up of Solid-Ice water and a natural gas like Methane gas trapped in the lattice of ice water. Gas hydrates are mainly found deep down in the sea where the atmospheric pressure is greater than 1 atm.
Generally Gas hydrates have two main applications.
a) It stabilizes the sea floor other wise its melting will cause land sliding in sea floor.
b) Secondly, it traps a green house gases like Methane, if released these gases could produce Climate changes.
