IV is the temp, DV how high it bounces. You need to keep the amount of air in basket ball size constant.
Sulfur dioxide has a molecular formula of SO2. The balanced
chemical reaction leading to this isas shown below:
<span>S + O2 --->
SO2</span>
Therefore this means that 1 mole of sulfur and 1 mole of O2
reacts to form 1 mol of sulfur dioxide.
Assuming 1 mol of O2 and 1 mol of S for the sake of
calculation, therefore:
mass oxygen, O = (1 mol O2) (2 mol O/ 1 mol O2) (16 g O/
mol O) = 32 g O
mass sulfur, S = 1 mol (32 g / mol) = 32 g
Therefore the ratio of O to S is:
O:S = 32 g O / 32 g S = 1 g O2/ 1 g S
<span>Hence, there is 1 g of oxygen per 1 g of sulfur in sulfur
dioxide.</span>
For atoms use a periodic table. The atomic number is the amount of atoms. For molecules and ions look up things revolved around the avogrados principle
Answer:
Distilation because they have different boiling points
The 3 isomers of pentane and their normal boiling points are:-
pentane, b.p approx. 36.C
iso pentane, b.p approx. 28.C
neo pentane, b.p approx. 10.C
Those differences in their boiling points make possible them to separate by Distilation.
Hope this will help....
Answer:
The structures are attached in file.
Hydrogen bonding and intermolecular forces is the reason for ranks allotted.
Explanation:
In determining Lewis structure, we calculate the overall number of valence electrons available for bonding. Making carbon (the least electronegative atom) the central atom in the structure, we allocate valence electrons until each atom has achieved stability.
In order of decreasing affinity to water molecules:
This is due to the fact that the will accept protons more readily than the bicarbonate ion, . Carbonic acid, will not accept any more protons, hence it is the least attractive to water molecule, even though soluble.
