No you cant survive
No
You can survive without your stomach. There are three main digestive organs...the mouth, stomach and small intestines. Without the stomach, you may have to eat smaller amounts at each sitting or you may have to adjust what you put into the system, but your body can still do some basic digestion and the bulk of the absorption of the food.
Yes, humans can live without a small intestine. See the related question below for how this can be accomplished. Also see the discussion section of this question for an interesting account of how one person managed to do this and the complications experienced.

BECAUSE YOU'RE HUNGRY. Yes, but here's more on that. the almost empty stomach is allowing gas to accumulate, when this gas enters the intestine it can make a gurgling or growling sound, even when you are not hungry this can happen deeper down in the intestine, it is why sometimes you stomach can make a noise even without you being hungry.
The lining of the small intestine is protected from stomach acid by a mucus layer that coats and lubricates the surface. Additionally, the small intestine secretes bicarbonate to help neutralize any acid that enters from the stomach. The rapid turnover of epithelial cells in the intestine also helps to repair and replace damaged cells.
A majority of the people who have their stomach removed have an advanced form of stomach cancer. They go through the surgery, which includes attaching a part of the small intestine to a manually inserted feeding tube. It's very possible to live a good, healthy life without a stomach.
