Ответ:

1)4P + 5O2 = 2P2O5

P2O5 + 3H2O = 2H3PO4

H3PO4 + 3NaOH = Na3PO4 + 3H2O

2)CuO + 2HCl = CuCl2 + H2O

CuCl2 + 2NaOH = Cu(OH)2 + 2NaCl

Cu(OH)2 + H2SO4 = CuSO4 + H2O

3)CaO + H2O = Ca(OH)2

Ca(OH)2 + 2HCl = CaCl2 + 2H2O

CaCl + Na2SO4 = CaSO4 + 2NaCl

ПЕРЕВЕДИТЕ ПОЖАЛУЙСТА ТЕКСТ!!!!!!! ОЧЕНЬ СРОЧНО!!!!!!!!There we were. At lact. l saw Devil' s cliff- it was big, no, it was huge! And suddenly l fekt sick, a lot of butterflies in my stomach. And l got thirsty. Maybe it was all the sun. There was a lot of sun, too much. l put my  sunglasses on, but it did not work. l was thirsty, too thirsty to talk and too sick to climb the rock. l poked Ralf in the side. He didn' t pay any attention. He had one hand up to his fotehead, shielding his eyes from the bright sun. "lt' s great, it' s really great," he muttered. "Let' s find some water, Ralf. l' d like some water." "Not now, " he said. He was looking up at the top of the cliff. l got angry. "Not funny, Ralf. You want me to die here, don' t you?" He didn' t turn his head as he kept staring at the cliff. "Stop acting like you' re a kid. Remember why we came here. There must be treasure here somewhere. We' ll be rich, Andy, we' ll be rich." l couldn' t tell him that all l wanted was to get on my bike and tide back home as fast as l could. " Can l have a drink first?" l sounded firm, or at least l hoped l did.He seemed irritated, but at last l got his attention. "Now, look, "  he said, pulling out the map l knew so well, " we have to hurry and get to the top before the sun starts to go down." "Oh, no, " l thought, but took my backpack and made myself take the first step up the tiny path.
