Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.
Answer: 111g S
Explanation:
SO2 you have = 665 g

S molar mass = 32.065 g/mol
A. I think the water may either rise up or it could leak out into the pie pan.
B. The air pressure would increase inside the glass, because you're adding a large amount of air into it.
It changes when you have started pushing the rock because at that moment it has started moving
Answer:
a) 0.30
Explanation:
Kc = [C] [D] / ([A] [B])
Set up an ICE table:
![\left[\begin{array}{cccc}&Initial&Change&Equilibrium\\A&0.4&-x&0.4-x\\B&0.4&-x&0.4-x\\C&0&+x&x\\D&0&+x&x\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D%26Initial%26Change%26Equilibrium%5C%5CA%260.4%26-x%260.4-x%5C%5CB%260.4%26-x%260.4-x%5C%5CC%260%26%2Bx%26x%5C%5CD%260%26%2Bx%26x%5Cend%7Barray%7D%5Cright%5D)
Plug in values and solve:
9 = x² / (0.4 − x)²
3 = x / (0.4 − x)
1.2 − 3x = x
1.2 = 4x
x = 0.3
