Sodium hydrogen carbonate is a weak base, therefore it does not harm the stomach and reduces the stomach acid. Sodium hydroxide is too caustic and not easily buffered and is almost a very strong base. It has a low solubility and dissociation constant, and causes chemical burns in the mouth & throat
When atoms bond together to form molecules, they share or give electrons. If the electrons are shared equally by the atoms, then there is no resulting charge and the molecule is nonpolar.
Answer:
Assuming that the atmospheric pressure is standard, the temperature will rise steadily until it reaches 100°C
Mirrors reflect light and lenses refract light.
Mirrors form images by reflecting all light that is incident on their surface, which allows us to see the reflections of objects in mirrors. Lenses, on the other hand, bend light and allow it to pass through them. The bending of light is used to form enlarged images, and for many other purposes as well.
