Answer:
All unexpected changes: color change (two clear liquids make purple), temperature change, Odor change or formation, precipitate formation (solid forms), and the production of gas.
Explanation:
When we talk about the gram weight of any food item, it may or may not include the gram weight of its different nutrient molecules. It may have different reasons to it. One of the reasons can be because the nutrient molecule might contain a large percentage or proportion of water. Also, the nutrient molecules might be insoluble or indigestible fiber so it does not add up to the total gram weight of food.
Answer:
2 molecules of water represents 3.32 x 10^-24 moles of water.
Explanation:
To find the solution to this problem, you have to use the concept of Avogadro´s number, that is in 1 mol of any element o compound there are 6.022 x 10^23 molecules. Then,
1 mol H2O ------------- 6.022 x 10^23 molecules
x= 3.32 x 10^-24 ---- 2 molecules.
2 molecules of water represents 3.32 x 10^-24 moles of water.
The first one is some reaction with water even I am studying the same
