No, it is a chemical change.
sawdust pilling under the table.
No. Antacids neutralize the hydrochloric acid in the stomach. It is a chemical change.
Sawdust is not a change. Making solid wood into sawdust by sawing it, would be a physical change.
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.
Taking an antacid is an example of a chemical reaction known as a neutralization reaction. In this reaction, the antacid reacts with stomach acid to form water and a salt, which helps to reduce acidity in the stomach.
Is an example of chemical change, reacting to air
The reaction between an antacid and stomach hydrochloric acid (HCl) is an example of neutralization because the antacid, which is a base, reacts with the stomach acid, which is an acid, to form water and a salt (such as magnesium chloride or aluminum chloride), neutralizing the acidity in the stomach. This reaction helps alleviate symptoms of heartburn or indigestion by balancing the pH levels in the stomach.
a substance that can neutralize the acid by reacting with hydrogen ions.
This is an example of chemical weathering, as the acid rain is reacting chemically with the minerals in the rocks to break them down.
An example of reacting to a stimulus is pulling your hand away when you touch something hot. The sensory input of feeling the heat triggers a reflex that causes you to quickly move your hand to avoid injury.
Gross is an amount of something. For example, if someone gave you a gross of apples; you would have 144 apples. A gross of antacid is too vague. you need to determine what the unit of the item is. Is it per bottle, per tablet, per case, what?
