Answer:
D. Gases have weak intermolecular forces between them
C6H6(l) + 6 Cl2(g) = C6Cl6(s) + 6 HCl(g)
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the final pressure by using the Boyle's law as an inversely proportional relationship in pressure to volume at constant temperature:
Thus, we solve for our target, P2, to obtain:

Answer:
2Al2O3 --> 4Al + 3O2
Explanation:
Ok so balancing equations means that there is an equal amount of atoms on both sides.
So let's list how much there is on each side
Reactants:
Al-2
O-3
Products:
Al-1
O-2
First of all, oxygen has 2 on the products side but 3 on the reactants side. If you add a 2 to Al2O3 and a 3 to O2, they will have the same amount.
Al-4
O-6
-----
Al-1
O-6
Ok now we need the Al to be balanced. This can be done by putting a 4 in front of Al.
Al-4
O-6
-----
Al-4
O-6
It looks like a lot of work but over time you should be able to just look at it and know what's missing!!
