Answer:
B. Solution
Explanation:
According to the question statement, Susan wrote in her notebook that it was a blue liquid. Therefore, from a chemistry point of view, it was a solution and not a heterogeneous mixture. Then, the solvent was evaporated after leaving the solution for 72 hours at the windowsill. The solute (blue color most likely) however was not able to evaporate with solvent and left behind.
Example: if you leave the KMnO4+water solution for a few days, water will evaporate thus leaving behind purple crystals of KMnO4.
Turtle nest can be destroyed or exposed where they could be poached or eaten by local wildlife
The correct answer is B. The temperature of the water decreased by 5°C
Explanation:
Temperature and the changes in it are part of quantitative observations because these can only be measured and understood through numbers. Indeed, the temperature is globally measured through different numerical scales such as the Celsius or the Kelvin scale. This does not occur in other qualities such as color because this is considered and analyzing using qualities or traits rather than values. According to this, the correct answer is "The temperature of the water decreased by 5°C."
B is the correct answer because it provide or throughout the photonics for the dark reaction
