1.ya live on one of the busiest streets of the city. 2.in the new city is not narrow, crooked streets. 3. on kutuzov avenue built a beautiful building panorama museum. 4.my arrived in sochi voskresene.gorod located along the black morya.sady and parks downtown sochi velikolepny.v many great magazinov.5.kartiny the museum made a big impression on me. 6.turisty always admired moscow metro.7.rossiyane very gostepriimny.8.ya live in a house located on the banks of reki.9.oni crossed the street and entered the dom.10.poezdka the city gave us a great udovolstvie.11.my tired after our trip to gorodu.12.tolpy people hurrying toward the subway station. 13.zapishite my address, not to forget. 14.kak once we arrived in volgograd, we immediately went to see the sights of this city-hero. 15.prostite you do not know how to get to sokolniki? , no. i really do not know much moscow. 16.v taxi for me was not mesta.17.davayte get out at the next stop and walk peshkom.18.ya go to college you do avtobusom.19.gde transplant (a change) on the way to work? -pushkinskaya ploschadi.tam i transplanted to the 31st trolleybus.20.vy exit at the next stop? yeah go. 21.vam would be better to stay at home, you nezdorovy.22.vy can tell what time it is? 23.prostite, can you tell me what is on petrovka trolley? -i think, № 69. 24.za recent years in moscow built many underground passages.
для катода:
E(O2/H2O2) = E°(O2/H2O2) + R ∙ T / ( z ∙ F ) ∙ ln ( pO2 ∙ a(H+)² / a(H2O2) )
где а - активность частиц в растворе, р - парциальное давление газа, z - кол-во е-, участв. в электродном процессе (для данной р-ции =2, для анодной =3, см. реакции)
для анода:
E(N2/NH3) = E°(N2/NH3) + R ∙ T / ( z ∙ F ) ∙ ln (√pN2 / (pNH3 ∙ a(OH-)³)
Здесь активность воды, как обычно, не указана, поскольку она постоянна.
Схема гальванического элемента:
анод(+) Pt, N2, NH3 | OH- || Н+, H2O2 | O2, Pt катод(–)
Для нестанд. ячеек необх. указать парц. давления газов и конц-и р-ров для всех в-в, участв. в реакции.
