Answer:
5.52cm³ of water will rise and might spill over the edge
Explanation:
Use the change in volume of a liquid with changing temperature equation which is written as
ΔV = β x V₀ x ΔT, where β is the coefficient of expansion, V₀ is the volume being submerged and ΔT is the difference in temperature
ΔV = (69 x 10⁻⁶) x (0.1 x 0.1 x 0.1) x (85 - 5)
ΔV = 5.52 x 10⁻⁶ m³
ΔV = 5.52cm³
Answer: Ions may be defined as the element that contains either positive or negative charge over them. Two types of ions are cations and anions. The outermost electrons are involved in the formation of ions.
The atomic number of sulfur is 16. Its outermost electronic configuration is K=2, L= 8, M= 6. The sulfur requres two more electrons to complete its orbit and accquire -2 charge.

The empirical formula of Lorelai's compound is C₄H₁₀O
<h3>Data obtained from the question</h3>
- C = 64.8 g
- H = 13.62 g
- O = 21.58 g
- Empirical formula =?
<h3>How to determine the empirical formula</h3>
Divide by their molar mass
C = 64.8 / 12 = 5.4
H = 13.62 / 1 = 13.62
O = 21.58 / 16 = 1.35
Divide by the smallest
C = 5.4 / 1.35 = 4
H = 13.62 / 1.35 = 10
O = 1.35 / 1.35 = 1
Thus, the empirical formula of the compound is C₄H₁₀O
