Answer:
if we're talking about beryllium then the answer should be 2 because it wants to move 2 spaces back (losing electrons) to become a Nobel gas so the answer is 2+
Explanation:
it has 2 valence electrons YW :)
1.A (when acids react with organic molecules on your skin the reaction is highly exothermic which is why it burns you)
2.C (acids and bases can dissociate into ions or create ions)
3. B (bases tend to taste bitter an example being soap)
4.A (acids tend to taste sour an example being citric acid from lemons)
5. A (the arrhenius acid definition is that acids dissociates into H⁺ ions)
6. B (the arrhenius base definition is that bases dissociate into OH⁻ ions)
7. C (Strong acid-strong base or weak acid-strong base reactions form water and salts)
8. A (I have heard that some metals can be corroded by some bases but I don't think bases usually corrode metal)
9. A (acids have lower pH values with 7 being neutral)
10. B (bases have higher pH values with 7 being neutral)
11. A (these are some of the strong acids)
12. B (these are some of the strong bases)
I hope this helps. Let me know if anything is unclear.
Answer: formic acid
Explanation:
HCOOH is the structural formula for the compound commonly known as formic acid.
According to the international union of pure applied chemist (IUPAC), it is named methanoic acid, and represent the first member of the alkanoic acids.
Thus, examples of alkanoic acids are
- formic acid (HCOOH)
- Acetic acid (CH3COOH)
- Propanoic acid (CH3CH2COOH) etc
They are reverse processes. Synthesis is combining one or more element/compound to form a new one. e.g photosynthesis
Decomposition is the opposite of that. It's when an element/ compound decomposes into it's component elements or simpler compounds
e.g 2H2O (l) --> 2H2 (g) + O2 (g)
