Answer:
(1) atomic numbers
Explanation:
The observed regularities in the properties of the elements on the periodic table are periodic functions of their atomic numbers.
- Atomic number is the number of protons in an atom.
- The periodic law states that "the properties of elements are a periodic function of their atomic number".
- Elements on the periodic table are arranged based on the atomic numbers they contain.
- The number of positively charged particles in an atom is the atomic number.
A.electrons are shared between two different nuclei
Answer:
Δ should be 0.1009
Explanation:
The change in the units volume when temperature change can be expressed as:
∆v = v0Δ
with v0 = the initial volume
with = the volumetric temperature expansion coefficient
with Δ = the change of temperature.
To calculate the final volume vf we'll get:
v = v0 + ∆ = v0(1 + Δ)
The liquid just begins to spill out if v(benzene) = :
v()(1 + Δ) = = v() (1 + Δ)
(v(cavity)-v(benzene))/(((benzene) -(copper)) = Δ
((1.22*10^-3)-(1.1*10^-3))/((1240*10^-6)-(51*10^-6)) = Δ
Δ = 0.1009
Δ should be 0.1009
