The first scientist to suggest grouping substances into acids and alkalis was the French chemist Antoine Lavoisier in the 18th century. He categorized these substances based on their chemical properties and reactions.
No, ethanoic acid is not an alkali. It is a weak organic acid commonly known as acetic acid. Alkalis are substances that are bases and have a pH greater than 7, while ethanoic acid has a pH less than 7.
It depends on the concentration and specific type of acid or alkali. In general, concentrated acids tend to be more corrosive and can cause severe chemical burns, while concentrated alkalis can also be harmful if they come into contact with skin or eyes. Both acids and alkalis should be handled with care and caution.
One piece of evidence is the observation of gas bubbles forming when hydrogen peroxide decomposes, indicating the release of oxygen gas. Additionally, changes in color or temperature during decomposition can suggest the formation of different substances. Finally, chemical tests or spectroscopic analysis can confirm the presence of smaller substances produced during the decomposition of hydrogen peroxide.
True. Light, heat, and gas production are indications of a chemical change. These signs suggest that a chemical reaction is taking place, which involves the formation of new substances with different properties than the original substances.

No, but sometimes bones can tell you which racial grouping the person was from, and that can sometimes suggest skin color.

Charles Darwin was the first scientist to suggest that plants and animals evolved over time. Darwin was also the first scientist that did early studies in selective breeding.
Another scientist might suggest the hypothesis that an increase in predation by natural predators of salamanders could be causing the decrease in their numbers. This could be investigated by studying predator populations, their behavior, and their interaction with salamanders in the ecosystem.
