This reaction contains pure solids which are not considered when writing out equilibrium constant expressions.

O2...........SO2

I 2.9...........0

C -x.......... +x

E 2.9-x........ x

Q=0/2.9 = 0 ---->Q<K Reaction will go to the right

Since the coefficients are all 1, I won't bother putting in the exponents.

k=B/A

1.5= x / (2.9-x)

4.35 - 1.5x = x

2.5x = 4.35

x= 1.74

plug back in ice chart

2.9 - 1.74

=1.16

=1.2 ANSWER

I would think it is a heterogeneous mixture since it can't be an element since there are more than one type of atom, it can't be a compound since the leaves are not bonded together, and it can not be a homogeneous mixture since the leaves don't all blended together (the pile is not uniform) and you can distinguish all the different parts of the mixture.  It can be considered a heterogeneous mixture since the leaves are mixed together (along with other things like dirt) in a non-uniform way so that you can point out the parts of the mixture and it does not look like one thing.

I hope this helps.  Let me know in the comments if anything is unclear.

Feliz [49]

Answer:

Q = 3440Kj

Explanation:

Given data:

Mass of gold = 2kg

Latent heat of vaporization = 1720 Kj/Kg

Energy required to vaporize 2kg gold = ?

Solution:

Equation

Q= mLvap

It is given that heat required to vaporize the one kilogram gold is 1720 Kj thus, for 2 kg

by putting values,

Q= 2kg ×  1720 Kj/Kg

Q = 3440Kj
