Ответ:
При проведенні реакції між граном Na із HNO3 на балансовку отримуємо наступне рівняння:
2Na + 2HNO3 → 2NaNO3 + H2
З рівняння видно, що для реакції необхідно 2 грами Na на 2 моля HNO3. Тому якщо в розчин додати 1 моль HNO3, це відповідає 2 грамам.

Краткий пересказ пожалуйста We worked all night and in the morning, the ship left Bristol. The Hispaniola was a good ship and we had good weather. The sailors all liked Long John Silver. In the old days, before he lost his leg, he was a good fighter, some of them said. He was always very good to me. Mr Trelawney liked to give the sailors things to make them happy. There was always a big barrel of fruit for them. One night, after I finished my work on the ship, I went to get some fruit from the barrel. Everything was very quiet. I climbed inside the barrel to get the fruit. Suddenly a heavy man sat down next to the barrel. He began to speak. It was Long John Silver. I stayed very quiet. "Yes,' he said. 'Flint was our captain. I sailed with him many times. We had one big fight. I lost my leg and Old Pew lost his eyes. I saw a lot of fighting and a lot of treasure, too. Ah.' said a younger man. 'Flint was a bad man! And where are all Flint's men now?' Most of them are here,' said Silver quietly, 'on this ship. Old Pew's dead. And you, young man, do you want to help us? Do you want to be a pirate?' 'Yes I do.' 'Good.' said Silver. 'You're going to be a good pirate.' Then a second man spoke to Long John Silver. It was Israel Hands. " don't like our captain, John,' he said. 'Let's kill Smollett and the others.' 'No. We must wait. We must have Captain Smollett to sail the ship,' said Silver. 'And Mr Trelawney and the doctor have the map. Let them find the treasure first. Then we can kill them. Now get me some fruit from this barrel.' I was very afraid. But then someone said, 'Land!' Everybody ran to see the island. I waited for a minute, then I climbed out of the barrel and ran, too. The ship was now quite near an island. 'Does anybody know this island?' Captain Smollett asked. 'I do,' said Silver. 'There were a lot of pirates here in the old days. That hill in the centre of the island is called the Spy Glass.' Then Captain Smollett showed Silver a map of the island. Silver looked at the map very carefully, but it was not Billy Bones's map. It did not show the treasure. I went to Dr Livesey. 'Can I speak to you please, doctor? I said. 'What is it, Jim?' he asked. Then I told the doctor, Mr Trelawney and Captain Smollett about Long John Silver. 'Most of the sailors are pirates,' I said. 'They want to kill us and take the treasure.' "Thank you, Jim,' said Mr Trelawney. "And Captain Smollett, you were right. I was wrong. I'm sorry.' 'Silver is a very clever man,' said the doctor. We all liked him.' 'What are we going to do, captain?' asked Mr Trelawney.
