2. They taste sour, are electrolytes, and react with active metals to produce hydrogen.
3. You should NEVER taste unknown chemicals because many are poisonous and can destroy body tissue.
4. Most often dyes are used to detect acids. The dyes will turn a certain color which indicates the presence of an acid.
10. You can use litmus to detect wether a solution is a base or an acid.
11. The most common bases I can think of would be: baking soda, laundry detergent, or soaps.
12. Antacids work by neutralizing the acids in your stomach.
13. When an acid and base are mixed together, they produce a salt.
14. Normally pH meters are used, but you can also calculate the pH using math. (yuck)
15. The pH scale measures how acidic or basic a substance is. It ranges from 0-14, with 7 being neutral.
17. pH is very important to the environment as it helps us measure and monitor for safe water conditions. A rise or fall from the average water pH level can indicate chemical pollution.
18. Salt is formed when an acid and base react with each other. It then has a cation of the base, and anion of the acid.
I hope those helps!! (:

Answer:
I think they are beneficial for the life of those symbiotic organisms that require yes or yes from another to be able to live.
Although an ecosystem could not be carried out if only this relationship would occur, since symbiotic relationships we have an organism where it needs another to live and even removes the necessary nutrients for it, that is why the chain should continue with other types of relationships .
Explanation:
The symbiosis is defined as "Intimate association of organisms of different species to mutually benefit in their vital development" that is why adequate coexistence between these living organisms is needed, otherwise this phenomenon would not occur.
A very good example of the symbiosis is: Bees and plants where the bee is the pollinating agent of the plant so that it continues to reproduce and the plant is the bee's food source.
Therefore I believe that the development of this type of relationship is VITAL, and very fundamental, otherwise I do not know if an ecosystem or a balanced ecosystem could be carried out.
2.70x10^23 molecules F2 x__1 mol F2____________ x38gF2__
6.02x10^23 mc F2 1mol F2
then solve
D.
230/50=4.6
So if you break up 230 km into intervals of 50 km you get 4.6 which would be 4.6 hours
