: negative
b)
: positive
c)
: positive.

f)
: positive.
Explanation:
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.
a) 
As ions are moving to solid form , randomness decreases and thus sign of
is negative.
b) 
As solid is changing to gas, randomness increases and thus sign of
is positive.
c) 
As 2 moles of reactants are converted to 4 moles of products , randomness increases and thus sign of
is positive.
d) 
As gas is changing to solid, randomness decreases and thus sign of
is negative.
e) 
As 7 moles of reactants are converted to 8 moles of products , randomness increases and thus sign of
is positive.
f)
As solid is changing to gas, randomness increases and thus sign of
is positive.
2Fe + Cl₂ -> 2FeCl
4Fe + 3O₂ -> 2Fe₂O₃
Answer:
If you increase the mass at a given force the rate of acceleration slows. Therefore, mass is inversely proportional to acceleration.

Answer:
K = 3.45
Explanation:
In the reaction:
SO₂(g) + NO₂(g) ⇄ SO₃(g) + NO(g)
And K is:
K = [SO₃] [NO] / [SO₂] [NO₂]
<em>Where [] are concentrations in equilibrium, as volume is 1L, [] could be taken as moles.</em>
Equilibrium concentrations are:
[SO₂] = 2.00 moles - X
[NO₂] = 2.00 moles - X
[SO₃] = X
[NO] = X
AS moles of NO are 1.3 moles, X = 1.3 moles
Replacing:
[SO₂] = 0.7 moles = 0.7M
[NO₂] = 0.7M
[SO₃] = 1.3M
[NO] = 1.3M
K = 1.3M² / 0.7M²
<h3>K = 3.45</h3>
