Answer:
: -ve
: -ve,
: +ve
Explanation:
Endothermic reactions are those in which heat is absorbed by the system and exothermic reactions are those in which heat is released by the system.
for Endothermic reaction is positive and
for Exothermic reaction is negative.
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and
is negative when randomness decreases.

As 15 moles of gaseous reactants are changing into 18 moles of gaseous products, randomness is increasing and thus
is positive.
Using Gibbs Helmholtz equation:



Thus
is negative ,
is positive and
is negative.
Answer:
10 moles of S₈
320 moles O₂
Explanation:
The balanced equation is:
Now we can convert moles of SO₈ (the product) into moles of each reactant, using the <em>stoichiometric coefficients of the balanced reaction</em>:
- 80 mol SO₈ *
= 10 mol S₈
- 80 mol SO₈ *
= 320 mol O₂
In order for 80 moles of SO₈ to be produced, 10 moles of S₈ need to react with 320 moles of O₂.

Brainlest is apprciatedddddddddddd
Plug in any number that yo think it’s the answer and make a t chart and put every letter in it and the other side the number until it is balanced
Because we say humid air “feels” heavier, more dense, more oppressive. ... Technically there is no direct connection between air pressure and humidity, humidity is the amount of water vapor in the air or air parcel. Air pressure is the weight of the air in a column. The only true connection would be the temperature.
