Animals use oxygen to convert this food into energy they can use, and to maintain a steady supply of carbon atoms that are necessary for building any animal cells. Respiration also returns carbon dioxide back to the atmosphere as a waste product, where plants can reabsorb it in the process of photosynthesis. hope I helped.
Answer:
<h2>Acetylene to ethene</h2>
First, acetylene is converted into ethene ( CH2 = CH2 ) using hydrogen gas and Lindlar catalyst. Ethene is an an alkene compound.
<h2>Lindlar catalyst</h2>
Alkynes are converted to alkenes by in the presence of hydrogen gas and lindlar catalyst.
lindlar reagent contains CaCO3, Pd and various forms of sulfur and lead
<h2>Ethene to ethanol</h2>
Then ethanol is prepared from the reaction of ethene with dilute sulfuric acid.
I got 1.97 times 10 to the 23rd power. no idea if its right
<span>Now. a 1m (that is a 1molal) solution is prepared by disssolving the molar mass in grams of the solute in 1kg or 1000g of solvent
Therefore a 0.244m solution is prepared by dissolving 32.0420*0.244 = 7.818g CH3OH in 1000g water
But you want to use only 400g water:
mass required = 7.818*400/1000 = 3.127g
Answer: dissolve 3.13g CH3OH in 400g water.</span>
