Reduction is a term which means that electron is gained while oxidation is a term which means that electron Is lost.
The species that gain electron is known as the oxidizing agent while the species losing electrons is known as the reducing agent
Answer:
Nope, not a chemical change.
Explanation:
i hope this helps ok bye luv!!!!!!!!!!!!!!!!!!!!
The following compounds and the number and type of ions are as follows:
Gold and chloride:
Gold (III) = Au 3+
Chloride = Cl 1-
Calcium and Sulfate:
Calcium Sulfate:
Calcium = Ca 2+
Sulfate = SO4 2-
Magnesium and Hydroxide
Magnesium Hydroxide: Mg(OH)2
Magnesium: Mg 2+
Hydroxide: (OH) 1-
MNaHCO₃: 23+1+12+(48×3) = 84g
mCH₃COOH: 12+(1×3)+12+(16×2)+1 = 60g
.................
84g NaHCO₃ react with 60g CH₃COOH
83g NaHCO₃ react with...........
84g ----- 60g
83g ----- X
X = 59,29g CH₃COOH
We used 70g CH₃COOH, it' too much.
So, acetic acid is excess reagent, and sodium bicarbonate is limiting reagent.
_______________________________
B) Amount of CH3COOH is in excess.
