While the material retains its chemical makeup, the physical property may be examined. The given statement is true.
The matter can undergo variations in physical or chemical properties. The physical changes of a matter occur when the matter undergoes changes in its physical properties like changes in the state of matter, weight, color, etc.
But the chemical composition of matter will remain constant if it undergoes a physical change. Whereas in chemical change, the matter undergoes a change in the composition of the substance but there will be no change in the physical properties.
Hence, The assertion is correct in that physical properties can be seen while the substance's chemical makeup stays constant.

Answer: All of them are true
Answer: The product from the reduction reaction is
CH3-CH2-CH(CH3)-CH2-CH2OH
IUPAC name; 3- Methylpentan-1-ol
Explanation:
Since oxidation is simply the addition of oxygen to a compound and reduction is likewise the addition of hydrogen to a compound.
Therefore, hydrogen is added onto the carbon atom adjacent to oxygen in 3- methyl pentanal
CH3 CH2 CHCH3 CH2 CHO thereby -CHO( aldehyde functional group) are reduced to CH2OH ( Primary alcohol) which gives;
3-methylpenta-1-ol .
The structure of the product is:
CH3-CH2-CH(CH3)-CH2-CH2OH
Answer:
12
Explanation:
If you look at the periodic table, you can see that magnesium has an atomic mass of 24.305. Subtract the number of protons from this to get neutrons.
24.305 - 12 = 12.305
12.305 is the average amount of neutrons a magnesium atom can have. A magnesium atom can have 12, 13, or 14 neutrons. The average, based on the natural abundance, is 12.305. To find which isotope is more abundant, you need to pick the number that is closest to the average. This would make the most abundant isotope the one with 12 neutrons.
