Answer:
6.59 g/cm³
Explanation:
Step 1: Given data
- Side of the cube (s): 2.54 cm
- Mass of the cube (m): 108 g
Step 2: Calculate the volume of the cube
We will use the following expression.
V = s³ = (2.54 cm)³ = 16.4 cm³
Step 3: Calculate the density of the solid
Density is an intrinsic property, equal to the quotient between the mass and the volume.
ρ = m/V
ρ = 108 g / 16.4 cm³ = 6.59 g/cm³
Answer: B. Ca2+ + 2e- ---------> Ca
Explanation:
Reduction involves the gaining of electrons as well as a decrease in the oxidation state of the atom or ion.
In this case; Ca2+ gains two electrons and the oxidation state is reduced from +2 to 0.
Ca2+ + 2e- ---------> Ca
