Though antacid R) is not a pure, chemically defined compound, the answer is most expectedly: "Physical only".
R) "An antacid medical tablet may contain any substance, generally a base or basic salt, which neutralizes stomach acidity"
It wouldn't be nice, would it, for the stomach if a chemical reaction took place when taking the tablet with water.
Dissolving sodium carbonate in water is a physical change, not a chemical change. This is because the chemical composition of sodium carbonate remains the same before and after dissolving.
Well, honey, when that antacid tablet hits the water, it's like a party in a glass! Technically speaking, the tablet dissolving is a chemical change because the composition of the tablet is changing as it reacts with the water. So, yes, it's a chemical change, but don't worry, it's just science doing its thing.
No, dissolving powder into water is a physical change, not a chemical change. The powder molecules are still the same chemical compounds as they were before dissolving, just dispersed in the water molecules.
Dissolving NaCl in water is a physical change, not a chemical change. The NaCl molecules remain the same chemically, but the arrangement of the particles changes as they interact with water molecules.
This change is a physical change because the matter is made up of the same components that it consisted of before it was broken. An example of a chemical change is the molecular rearrangement of matter like rust on a car.
Dissolution is a physical change.
