Mass of object A = 10g
volume of object A = 8cm³
Mass of object B = 10g
Volume of Object B = 6cm³
we use the following formula to calculate the density of object A and B.
Density = Mass / Volume
Density of Object A = 10g / 8cm³ = 1.25g/cm³
Density of Object B = 10g / 6cm³ =1.67 g/cm³
So the density of object B is greater than object A
and if we find the difference:
1.67 - 1.25 = 0.42
So the answer is; Object B, by 0.42 gram per cubic centimeter
The hybridization will be sp3. I hope that is helpful.

NaOH (s) is in solid state and NaOH (aq) is an aqueous solution.
The answer to this question would be because reaction that joining sugar will produce a water molecule.
The condensation reaction is a reaction that will combine two or more molecule and produce a small molecule like water. Reaction to create disaccharide(lactose, sucrose) sugar will need two monosaccharide sugar molecule and produce a bigger sugar(twice as big) and water.
