Answer:
for the reaction is -198.762 J/K
Explanation:
Standard change in entropy for the system () is given by-
where represents standard entropy.
Here , and
So,
Answer:
Explanation:
You would have to add up the atomic masses of all the compounds in the compound, making sure you include how many molecules of each are in the compound
For example, in CuSOA we have 1 molecule of Cu and S, as 4 molecules of O
The atomic masses are as follows:
Cu = 63.55 u
S = 32.065 u
O = 15.99 units
This is how we would add it up:
(Atomic mass of Cu) + (Atomic mass of S) + 4(Atomic Mass of O)
(63.55) + (32.065) + 4(15.99)
(63.55) + (32.065) + 63.96
= 159.575 u
Answer:
Remaining the same
Explanation:
By the Lavoisier's principle the matter can't be created nor destroyed, but always transformed.
It means that in an ecosystem, the matter, and also the energy, is not increasing and not decreasing, the total amount remains the same, but in different forms.

C

<span>Electronegative atoms or atoms where electrons spend more of their time orbiting the atom's nucleus giving the atom a negative charge. When electronegative atoms such as oxygen bond to hydrogen they pull the hydrogen's electron to themselves becoming even more electronegative. This causes the hydrogen side to become positive. The molecule formed is a polar molecule. Molecules with positive ends and negative ends are called polar.</span>
