B. Sugar is a pure substance.
It is sugar because sugar is made up of one atom or molecule.
A) penny is not correct because a penny is made up of copper, zinc, and tin.
C) ocean water is not correct because its made out of water (h2o) and salt.
D) iced tea is not correct because it takes many atoms to combine in order to make tea, then you have to add water and ice to make it an iced tea.
Hope this helps! :)
Flourine.
You are very welcome
<span>The
list of phases of H2O that is arranged in order of increasing entropy is from
solid then liquid then gas. Gaseous water has the most entropy because of the
random movement of water molecules. And Solid having the least entropy because the
water molecules are arranged in a specific order.</span>
Answer:
The new pressure exerted by the He, is 1266.6 Torr
Explanation:
A typical problem of gases where the volume is increased and the moles and T° keeps on constant. This is an indirect proportion because when the volume of the flask is increased, pressue decreases because molecules collide to a lesser extent with the walls of the vessel.
P₁ . V₁ = P₂ . V₂
760 Torr . 5L = P₂ . 3L
P₂ = (760 Torr . 5L) / 3L
P₂ = 1266.6 Torr
Answer:
See explaination
