Calculate the work done (in joules) by the reaction 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)

when 0.81 g of Na reacts with water to form hydrogen gas at 0°C and 1.0 atm.

Exothermic,  physical change after it is already baked

Ibelieve the answer is d. titaniumhope my answer has you : )

B.1 - hydrogren-1 can only mean there is 1 neutron. it's obvious there is 1 proton or else it wouldn't be hydrogen, so they wouldn't put a number after it unless they were indicating the number of neutrons

13 protons and 13 electrons
