WILL GIVE 22 POINTS How many moles of Sodium bicarbonate (NAHCO3)is needed to react with vinegar (CH3COOH), to produce 0.5 moles of Sodium acetate (Ch3COONa), and Carbonic acid(H2CO3)? (Show all your work) (5 Points)

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

a. they are both space stations

happy to

pls mark as brainliest.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
