Who was the first scientist to suggest groupin substances into acids and alkalis?
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.
Is ethanoic acid an alkali?
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.
Is acid more dangerous than alkali?
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.
What evidence shows that hydrogen peroxide decomposed into smaller substances?
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.
Is it true or false that indications of a chemical change include light heat and gas production?
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.

Who founded selective Breeding?
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.
What hypothesis might another scientist suggest to Harte for the decrease in the number of salamander?
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.
What processes deep within earth do scientist suggest causes plate movements on earth surface?
continental drift
