gasoline is the chemical that is coming out of the air
In here Oxygen is the central atom. It makes two bonds with
Cl and has two lone pairs. Since, the shape is bent and the hybridization is
sp3. Molecular geometry is a bit dissimilar from hybridization. Hybridization
is reliant on the number of bonds and lone pairs. Since O has two bonds with
Cl, its hybridization is sp3. It is like is this: 1 lone pair/bond = s. 2 lone
pairs/bond = sp 3 lone pairs/bonds = sp2, etc. molecular geometry, you count
the number of bonds and lone pairs. This has two bonds and 2 lone pairs so if
they were all bonds, the molecule would be tetrahedral.
The combustion reaction for butane is as follows ;
2C₄H₁₀ + 13O₂ ---> 8CO₂ + 10H₂O
Stoichiometry of butane to oxygen is 2:13
Number of butane moles reacted = 5.23 g / 58 g/mol = 0.090 mol
number of Oxygen moles reacted = 27.1 g/ 32 g/mol = 0.84 mol
we have to find which is the limiting reactant
if butane is the limiting reactant,
if 2 mol of butane reacts with 13 mol of O₂
then 0.09 mol of butane reacts with -13/2 x 0.090 mol = 0.58 mol
there are 0.84 mol of oxygen present but only 0.58 mol reacts therefore butane is the limiting reactant.
stoichiometry of butane to water is 2:10 = 1:5
the number of water moles formed = 0.090 mol x 5 = 0.45 mol
mass of water formed = 0.45 mol x 18 g/mol = 8.1 g
Answer:
<u><em>95 people can breath with five such trees supplying oxygen.</em></u>
Explanation:
Given data:
a man take in oxygen in a day : 22 (1 = 1000L)
Tree length: 33 m
Tree diameter : 0.55 m
tree produce oxygen in a year : 84,000 L
Tree oxygen in the air : 20%
1 = 1000 L
To find:
number of people can breath with 5 such trees: ?
Calculation:
Calculate the oxygen produced by 5 trees:
= 5 x 84,000
= 420.000 L
= 420
Calculate the air
= 420 x 100% / 20%
= 2100 m^3
Calculate the number of people:
= 2100 m^3 / 22 m^3
= 95.5
= 95 people
