Is this a tricky question, or what? In the first place, the question, I think, is a little off from the usual chemistry terminologies. Chemical properties cannot neutralize per se, but the chemical substances do. Secondly, gastric acid is basically HCl and a review of the identified chemical substances in Peperomia pellucida (PP) are not known to be strong bases and the pH of the PP extract is also not basic enough. Unless the components in PP can control acidity through some other mechanism, say, and antagonistic mechanism against the production and release of more HCl, I think the answer is NO, it cannot.
When you neutralize, it would be a chemical property.
chemical property
The chemical properties of calcium are most similar to (in between) the chemical properties of magnesium and strontium.
it changes chemical properties
This is a chemical property because it can only be observed in a chemical reaction.
A base, a basic oxide as CaO and a saline hydride as NaH will neutralize an acid.
Chemical properties are determined by experiments.
Physical and chemical properties of LPG
Dilute it or neutralize it with a chemical reaction.
If it's a chemical, it has chemical properties. An oreo churro (whatever unholy abomination that might be) is a mixture of chemicals, each of which will have their own chemical properties.
the chemical properties of bronze are pig and feet
helium is chemically inert and has no chemical properties
