I think the element is oxygen
The reaction is : C3H8 + 5O2 ===> 3CO2 + 4H2O
find the number of moles of H2O using the molar mass of H2O
moles of H2O = 75g/18.02 g/mol = 4.162 moles
go between the H2O and the propane to find the mole of propane
4.162 moles H2O its a 1 : 4 ratio so divide 4.162 / 4 = 1.041mol of propane
use this equation to find the volume of gas required : V = nRT/P
n is the moles of gas (propane)
R is the universal gas constant (0.082057338)
T is the temperature of the gas (273K)
V = (1.041) x (0.08206 L-atm/mol-K) x (273K)/(1 atm)
V = 23.3 L of C3H8
hope that helps
3 stereoisomers of the resulting alcohol were formed when Ethyl (r)-4-phenylhexanoate was treated with ethyl lithium followed by acid hydrolysis (to neutralize).
<h3>Stereoisomers:</h3>
In contrast to atomic connection, stereoisomers differ in the spatial arrangement of their atoms. The mirror-image stereoisomers, a non-superimposable pair of two molecules that are mirror images of one another, are one of their most intriguing types of isomers.
These include non-enantiomeric optical isomers, cis-trans isomers, E-Z isomers, and meso compounds. Rarely do diastereomers share the same physical characteristics. Stereoisomers are isomers that share the same structure (i.e., the same pieces), but differ in how those parts are arranged in space.

Answer:
Mass = 53.45 g
Explanation:
Given data:
Mass of propane = 200 g
Mass of S₂ = 75 g
Theoretical yield /Mass of CS₂ = ?
Solution:
Balanced Chemical equation:
C₃H₈ + 5S₂ → 4H₂S + 3CS₂
Number of moles of propane:
Number of moles = mass / molar mass
Number of moles = 200 g/ 44.1 g/mol
Number of moles = 4.54 mol
Number of moles of S₂:
Number of moles = mass / molar mass
Number of moles = 75 g/ 64.14 g/mol
Number of moles = 1.17 mol
Now we will compare the moles of carbon disulfide with both reactant.
S₂ : CS₂
5 : 3
1.17 : 3/5×1.17 = 0.702
C₃H₈ : CS₂
1 : 3
4.54 : 3×4.54 = 13.62 mol
Number of moles of CS₂ produced by S₂ are less so it will limiting reactant and limit the yield of carbon disulfide.
Theoretical yield of carbon disulfide.
Mass = number of moles ×molar mass
Mass = 0.702 mol × 76.14 g/mol
Mass = 53.45 g
