Answer:
Experiment you will be able to watch a chemical reaction. In this experiment vinegar (a substance) and baking soda (a substance) will mix together. When mixed together the molecules of the two substances will re-arrange, or change, to make new substances.
Vinegar has acetic acid in it. The chemical name for baking soda is sodium bicarbonate. When you mix the two together you get sodium acetate and water. You also get carbon dioxide, which is a gas. The bag puffs up because carbon dioxide is a gas and takes up a lot of space. Eventually the bag isn't big enough to hold all that carbon dioxide gas so it explodes!

Answer:
Alternative C would be the correct choice.
Explanation:
- The dual compounds were evaluated on something like a TLC plate through three separate additives in conducting a TLC study of ferrocene versus acetylferrocene.
- The polar as well as nonpolar ferrocene where nonpolar is about 0.63 with the maximum
value, and indeed the polar is somewhere around 0.19 with . - TLC plate (30:1 toluene/ethanol) established with.
The other three choices are not related to the given circumstances. So that option C would be the appropriate choice.
Answer:
1.044 g sample contains only vitamin C (C6H8O6) and sucralose (C12H19Cl3O8). When the sample is dissolved in water to a total volume of 33.0 mL, the osmotic pressure of the solution is 3.69 atm at 295 K.
Answer:
The volume of the marble is 10 mL.
Explanation:
From the question given above, the following data were obtained:
Volume of water = 10 mL
Rise in water = 10 mL
Volume of marble =.?
From the question given above, the water level rise by 10 mL when a glass marble was placed into the water.
This is equally the volume of the marble as the marble will displace it's volume when placed in the water according to Archimedes' principle.
Therefore,
Rise in water = 10 mL = volume of marble.
