Answer:
Q = 5555.6J
Explanation:
Mass of glass piece, m = 453g
initial temperature = 25.7°C
temperature to be attained = 40.3°C
⇒change in temperature, Δt = 40.3 - 25.7 = 14.6°C
specific heat of glass, s = 0.840J/g°C
Heat absorbed, Q = msΔt
⇒Q = 453×0.840×14.6 = 5555.592J
⇒<u>Q = 5555.6J</u> (rounded to the nearest tenth)
Answer:
There is two iron atoms.
Explanation:
The formula iron oxide is Fe2O3 F e 2 O 3 therefore there would be two. Hope this helps. :)
Answer:
In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell. As a result, each atom can consider the shared electrons to be part of its own valence shell.

Answer: -
A solar nebula is a rotating cloud of gas and dust from which the sun and the planets formed.
A planetesimal is a small body from which planet originated in the early stages of development of the solar system.
Kupier belt is region of the solar system that is just beyond the orbit of Neptune and that contains bodies made mostly of ice.
This is the region of the solar system that contains small bodies that are made mostly of ice.
Thus Pluto is formed from the huge disk of ice and debris beyond the outer planets. Comets originating from the Kupier belt are also composed of ice and debris.
