Answer:
P=19.32g/cm³
Explanation:
m=9.66g
v=0.5cm³
P=mass/volume (density formula)
=9.66/0.5
=19.32g/cm³
Answer:
The size of an isolated atom can't be measured because we can't determine the location of the electrons that surround the nucleus. We can estimate the size of an atom, however, by assuming that the radius of an atom is half the distance between adjacent atoms in a solid. This technique is best suited to elements that are metals, which form solids composed of extended planes of atoms of that element. The results of these measurements are therefore often known as metallic radii.

Answer:
The change in temperature of a coffee cup calorimeter is 8.87°C.
Explanation:
Volume of the water = V = 150 g
Density of the water , d =1.0 g/mL
Mass of the water = M
Mass of solution = m = M = 150.0 g
Moles of NaOH = 
Energy released when 0.125 moles of NaOH added in water = Q
1 kJ = 1000 J
Heat gained by water = Q' = -Q ( conservation of energy)
Specific heat of solution = c = 4.184 J/g°C
Change in temperature of the solution = 
The change in temperature of a coffee cup calorimeter is 8.87°C.
Answer:
Explanation:
Decomposition is the answer.
If a compound breaks into two or more parts then it is called decomposition.
