TPA catalysts based on tantalum oxide (Ta2O5) were produced and studied by FT-infrared, X-ray diffraction, Laser Raman, and temperature programmed ammonia desorption.
<h3>
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.

Answer: 11.2 grams
Explanation:
The balanced chemical equation for reaction is:
To calculate the moles, we use the equation:
a) moles of 
According to stoichiometry :
As sulfuric acid is in excess , the limiting reagent is barium chloride as it limits the formation of product.
1 mole of produces= 1 mole of 
Thus 0.0480 moles of require=
of
Mass of 
Thus 11.2 g of barium sulfate are produced if 10.0 grams of barium chloride are reacted is excess sulfuric acid
I think the correct answer is air!
Following are the types of chemical reactions with a brief overview:
<span>1) Combination (Two elements combine to form a compound)
2) Decomposition (A compound is broken into elements)
3) Single displacement (An element displaces an element present in a compound)
4) Double displacement (The elements of two compounds displace each other)
5) Combustion (Burning Takes places)
<span>6) Redox (Oxidation Reduction Reaction)
If you see the given equation, Al is displacing Ni in the compound NiSO4 and taking its place. Ni is set free as a separate element. So this type of reaction is known as Single Displacement Reaction.</span></span>
