Answer:
There are 0.93 g of glucose in 100 mL of the final solution
Explanation:
In the first solution, the concentration of glucose (in g/L) is:
15.5 g / 0.100 L = 155 g/L
Then a 30.0 mL sample of this solution was taken and diluted to 0.500 L.
- 30.0 mL equals 0.030 L (Because 30.0 mL ÷ 1000 = 0.030 L)
The concentration of the second solution is:
So in 1 L of the second solution there are 9.3 g of glucose, in 100 mL (or 0.1 L) there would be:
1 L --------- 9.3 g
0.1 L--------- Xg
Xg = 9.3 g * 0.1 L / 1 L = 0.93 g

Correct option:
The statement "America is the world’s number one producer of natural gas derived from shale oil" is True.
Shale gas:
- Shale, a form of sedimentary rock, is used to make shale gas, which is natural gas.
- Over the past ten years, shale gas has gained importance as a natural gas source in the United States. Interest has also grown in possible shale gas reserves in Canada, Europe, Asia, and Australia.
- With large production in the US and Canada, North America is the region that produces the most shale gas globally. Only Argentina and China have so far produced shale gas on a commercial basis outside of the US and Canada.
- The environmental dangers associated with shale gas production like, Induced seismicity from hydraulic fracturing has been known to cause earthquakes in three different places across the world and leaks of extraction waste and chemicals into water systems, the release of greenhouse gases during extraction, and the pollution brought on by the poor processing of natural gas have led to its suspension in numerous nations.

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!
