The mass of CO2 that would be produced is 144.03 g
From the equation of the reaction, the mole ratio of C2H4 input to CO2 produced is 1:2.
Recall that: mole = mass/molar mass
mole of 45.9 g C2H4 = 45.9/28.05
= 1.6364 moles
Thus: equivalent moles of CO2 = 1.6364 x 2
= 3.2727 moles
Mass of 3.2727 moles of CO2 = moles x molar mass
= 3.2727 x 44.01
= 144.03 g

<h3>Answer:</h3><h3>Law of inertia, also called Newton's first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force</h3>
Building blocks are the small units that make the larger, more complex molecule. The building block of protein is an amino acid and lipids are fatty acids and glycerols.
<h3>What are proteins and lipids?</h3>
Proteins and lipids are the biomolecules that are involved in major reactions in the living system. They are composed of smaller subunits joined together by bonds.
Proteins are molecules made up of amino acids linked by the peptide bonds to form the chain of proteins that plays a crucial role in cell functioning.
Lipids are composed of fatty acids and glycerol linked by the ester bond, essential for the storage of energy and in the composition of the membranes.
Therefore, proteins are composed of amino acids and lipids of fatty acids and glycerol.

Answer : The time taken for the reaction is, 28 s.
Explanation :
Expression for rate law for first order kinetics is given by :
where,
k = rate constant = 0.0632
t = time taken for the process = ?
= initial amount or concentration of the reactant = 1.28 M
= amount or concentration left time 't' =
Now put all the given values in above equation, we get:
Therefore, the time taken for the reaction is, 28 s.
