Answer:
2.53 L is the volume of H₂ needed
Explanation:
The reaction is: C₁₈H₃₀O₂ + 3H₂ → C₁₈H₃₆O₂
By the way we can say, that 1 mol of linolenic acid reacts with 3 moles of oxygen in order to produce, 1 mol of stearic acid.
By stoichiometry, ratio is 1:3
Let's convert the mass of the linolenic acid to moles:
10.5 g . 1 mol / 278.42 g = 0.0377 moles
We apply a rule of three:
1 mol of linolenic acid needs 3 moles of H₂ to react
Then, 0.0377 moles will react with (0.0377 . 3 )/1 = 0.113 moles of hydrogen
We apply the Ideal Gases Law to find out the volume (condition of measure are STP) → P . V = n . R . T → V = ( n . R .T ) / P
V = (0.113 mol . 0.082 L.atm/mol.K . 273.15K) 1 atm = 2.53 L
Answer:
The correct answer is option C.
Explanation:
Half life for second order kinetics is given by:
= half life = 15.4 s
k = rate constant =?
= initial concentration = 0.67 M
is the rate constant for this reaction.

Answer: The percent of sulfate is present in the coal samples is 0.999%.
Explanation:
Given: Percentage of sulfur present = 3%
In 
, the percentage by weight of Sulfur is calculated as follows.
This means that the amount of only sulfur present in in the sample is as follows.
Thus, we can conclude that percent of sulfate is present in the coal samples is 0.999%.
