For each mixture, she puts a smaller amount of solid into a larger amount of liquid. She is trying to determine if mixing these substances produces any physical or chemical changes. en-us 2021-01-19 02:50:33 UTC 2024-01-24 04:32:51 UTC hello@padlet.com Prompt: A scientist makes several more mixtures between solids and liquids.
