Answer:
Specific heat of water = 33.89 KJ
Explanation:
Given:
mass of water = 81 gram
Initial temperature = 0°C
Final temperature = 100°C
Specific heat of water = 4.184
Find:
Required heat Q
Computation:
Q = Mass x Specific heat of water x (Final temperature - Initial temperature)
Q = (81)(4.184)(100-0)
Q = 33,890.4
Specific heat of water = 33.89 KJ
Answer: <span>B. Each element has a unique arrangement of electrons.
Explanation:
1) Since the number of electrons in neutral atoms is equal to the number of protons, and the number of protons are unique for each element, each element has a unique arrangement of electrons.
2) The spectrum of an element is the radiation emitted for the atoms of the element when the valence electrons are emitted and that depended on the electrons configuration.
