Correct H H Part C Sketch the reson.
If we add 1 mole of acetic acid (carboxylic acid), then we will not obtain 1 mole of hydrogen ions or 1 mole of ions in the solution. This shows that carboxylic acid does not dissociate completely in water. Hence, carboxylic acid is a weaker acid than the inorganic acids. Hence, the given statement is true.
Let x be the mass of the ore in grams such that the equation that would allow us to answer this item would be,
55 = (x)(0.243)
The value of x is calculated as,
x = 55/0.243
x = 226.337 grams
Then, solve for amount in kilograms by dividing the calculated value by 1000. This methodology will give us an answer of 0.226337. Hence, the answer is 0.226.
Answer:
In organic chemistry oxidation is the gain of oxygen atoms by any carbon atom or molecules.
