<span>The cell would swell and burst, because the 20% salt solution is hypotonic with respect to the cell, causing a net movement of water into the cell. Example, water moves from the blood filtrate that will form urine. The same will do while pure water moved to seawater.</span>
Answer:
I believe its A
Explanation:
A molecule that has a symmetrical shape will be a nonpolar molecule.
This is called as such because the proton or H+ has taken on both lone electron pairs on the oxygen in the water molecule. As such it is s coordinate covalent bond.
TPA catalysts based on tantalum oxide (Ta2O5) were produced and studied by FT-infrared, X-ray diffraction, Laser Raman, and temperature programmed ammonia desorption.

How did Lewis acidity induced heteropoly tungstate catalysts?</h3>
Heteropoly tungstate was synthesised and spread over tin oxide containing tantalum ions in its secondary structure. Different spectroscopic approaches were used to estimate the physical and chemical characteristics of the produced compounds. The inclusion of Ta ions in heteropoly tungstate resulted in the formation of new Lewis acidic sites. These samples were evaluated for their ability to catalyse the conversion of fructose to 5-ethoxymethylfurfural (EMF) and the selective etherification of 5-hydroxymethylfurfural (HMF) with ethanol. The catalyst with 30% active component on SnO2 had the greatest HMF etherification activity, yielding 90% 5-ethoxymethylfurfural in 45 minutes. The catalysts were also capable of converting fructose into EMF in a single pot with a 68% yield.
