Answer is: <span>C. propanal.
1-propanol is primary alcohol. With weak oxidizing agent primary alcohol gives aldehyde and with strong oxidizing agent primary alcohol gives carbonic acid.
</span>Oxidation of 1-propanol with <span>Na</span>₂<span>Cr</span>₂<span>O</span>₇<span> and sulfuric acid</span><span> gives propanal and o</span><span>xidation with </span>chromic acid<span> gives </span>propionic acid<span>.</span>
Total moles of gas in the reactants: 4

Answer:
Explanation:
The density of an object is found by dividing the mass by the volume.
The mass is 12.1 grams, but we are not given the volume. Instead, we are told that the water before is 24.2 millilitres and the water after is 28.8 millilitres.
So, the volume was taken using water displacement. We can find the volume by subtracting the initial volume from the volume after the object was added.
- v= with object - initial
- v= 28.8 mL-24.2 mL=4.6 mL
Now we know the mass and volume:
Substitute the values into the formula.
Divide.
Let's round to the nearest hundredth. The 0 in the thousandth place tells us to leave the 3.
1 milliliter is equal to 1 cubic centimer, so the density can also be written as:
The density of the rock is approximately 2.63 grams per cubic centimeter.
