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!! (:
Waste materials, mining and transportation of radioactive fuels, radiation emissions from nuclear sites
Answer:
The bond that will be most polar amongst all these will be C-F.
Explanation:
The answer is Cs and F. S and O are both non-metals and if I am not mistaken they are both on the right side of the periodic table. S and O exhibit a covalent bond, the other pairs do too except for the first pair of atoms. Therefore, the answer is A. Cs and F.
So in order to answer this question you need to know how many moles are in 36.8g of magnesium. A mole of magnesium has a mass of 24.3 grams. 36.8/24.3 is about 1.51. This is how many moles are in 36.8 g of magnesium. Now you multiply this number by Avagadro's number which is 6.022E23. The total should be 9.12E23 atoms of magnesium.
