The most appropriate type of information for the government to use to make decisions is research reports containing scientific data.
<h3>What is pollution?</h3>
The term pollution has to do with the introduction of materials and energy that are harmful to the environment and also the fauna and flora.
1) The most appropriate type of information for the government to use to make decisions is research reports containing scientific data.
2) If the government committee learns about the side effects and decides the medication is not safe for public use, then the committee used an anecdote and did not use science to make the decision.
3) The type of research that might result in a law that restricts hunting of a particular species is research showing the species is endangered in other geographical areas
4) The statement that explains why a rare disease would get more research funding than a more common disease is; "organizations are concerned about the results of the research into the rare disease."
5) The product that the corporation is most likely manufacture is a sunscreen.

The molarity of HCl is calculated as below
find the moles of mg used
moles = mass /molar mass
= 2.00g/24 g/mol=0.083 moles
write the reacting equation
Mg(s) +2HCl (aq)= MgCl2(aq) + H2(g)
by use of mole ratio between Mg to HCl which is 1 :2 the moles of HCl is therefore
= 0.083 x2 =0.166 moles
molarity of HCl = moles of HCl/ volume in dm^3
that is 0.166/50 x1000= 3.3 M of HCl
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.
