Сделаю только первое задание, потому что для выполнения задания с графиком нужно фото самого графика.

Na2CO3 + 2HCl → 2NaCl + H2O + CO2

помогите с англ яз. часть 4bReading 4 a) Read the text below and mark the statements T (true), F (false) or DS (doesn't say). Roller Meals Don't expect a friendly smile from the waiter when you walk into 's Baggers restaurant in Nuremburg, Germany. There are no waiters in this unique and modern restaurant. Instead, customers look through the menu and order their meals on computer screens at their tables. Here, you don't need to wait for a waiter to say, "Are you ready to order?" When you're ready, just select what you want from the scree and wait for the kitchen staff to make your meal. That's not all. You can even send emails from your touch screen, so you don't get bored while waiting. Also, a waiter doesn't carry the meal to your table when it's ready. Your dish travels down long tracks from the kitchen to your seat. The tracks resemble a roller coaster ride and make the restaurant seem like a small amusement park. This restaurant also specialises in low-fat and low- calorie dishes. So when the food comes down, your weight doesn't go up! 1 There is no other restaurant like 's Baggers F 2 There isn't a menu at 's Baggers restaurant....... 3 Customers need to wear formal clothes.
