1. Energy as particles can't move without kinetic (movement) energy
2. I think it's Diffusion and Active Transport
Building a tower out of magnetic blocks and water vapor condensing on a bathroom mirror are only physical changes.
A physical change is easily reversible. It does not involve a change in the composition of a substance.
A tower built out of magnetic blocks can easily be pulled apart and water that condensed on a bathroom mirror can easily change back to vapour by heating.
All these are possible because the both processes are only physical changes.

Iodine value is a measure of the degree of unsaturation in fats and oils. It is essentially the number of grams of iodine consumed by 100 g of fat. If the iodine number is in the range of 0-70 then it is a fat, any value above 70 is considered an oil.
Formula:
Iodine number = (ml of 0.1 N Thiosulphate blank- ml of 0.1N thiosulphate test) * 12.7 *100/1000* wt of sample
vol of thiosulphate required to titrate test sample (given oil) = 1 ml
wt of sample = 0.2 g
Information on the volume of thiosulphate required to titrate the blank solution is essential for calculation.
Iodine number = (X-1.0) * 12.7 * 100/1000* 0.2 = (X-1.0)*6.35
Answer:
PbSO₃(s)⟶PbO(s)+SO₂(g)
Explanation:
In order for an equation to be balanced, both <em>the charges</em> and <em>the masses </em>need to be the same in both sides of the equation.
In the case of the reaction PbSO₃(s)⟶PbO(s) +SO₂(g), there are no charges in either side, so it is already electronically balanced.
Regarding masses, let's see each element one by one:
Pb ⇒ There's 1 Pb in both sides already.
S ⇒ There's 1 S in both sides already.
O ⇒ There're 3 O in both sides already.
So the equation is balanced as is.
