Answer:
Concept: Chemical Analysis
- You need to start by graphing the data and then analyzing it.
- We can see that the horse has a distance in meters of 980 at the end of the 10 seconds hence it is the fastest.
- The horse line has a linearly representation, while the alternate line has parabolic tendencies towards the end. The steeper line indicates a faster change in time or velocity which results in a greater distance traveled indicating that the horse is faster.
- *I have confidence you can graph that*
Answer:
The longer the path length, the more molecules there are in the path of the beam of radiation, therefore the absorbance goes up. As you likely know from other experiences, a particular chemical species absorbs some wavelengths of radiation and not others
Answer:
Chemical properties of acids are the following.
1) Acids have pH lower than neutral i. e. 0 to 6.
2) Acids have sour taste.
3) It changes the color of indicator from blue litmus to red.
4) When the acid react with base forming salt and water.
5) When acid react with metals it produces hydrogen gas.
6) Acid have the ability to corode metals.
