Answer:

nitrogen oxides and sulphur oxides

Explanation:

Factors responsible for antropogenic pollution are:

  • burning of fossil fuels
  • deforestation
  • mining
  • sewage
  • industrial effluent
  • pesticides, fertilizers, etc.  

The primary air pollutants released from burning of fossil fuels are oxides of nitrogen, sulfur oxides and carbon monoxide.

Out of which the main pollutants that are responsible for acidic precipitation are oxides of nitrogen and sulfur oxides.

Sulfur oxides and Oxides of nitrogen reacts with moisture present in the air to form sulfuric acid and nitric acid respectively.

These acids get mixed with rain and cause acidic precipitation.

Therefore, the correct option is oxides of nitrogen and sulfur oxides.

2 AIPO4 + 3 BaCl2 --> 2 AICIz + 1 Baz(PO4)2
givi [52]

Answer:

12.3 moles of AlCl_{3} are produced by reacting 18.4 moles of BaCl_{2} .

Explanation:

Balanced reaction: 2AlPO_{4}+3BaCl_{2}\rightarrow 2AlCl_{3}+Ba_{3}(PO_{4})_{2}

According to balanced equation:

3 molecules of BaCl_{2} produce 2 molecules of AlCl_{3}

So 3N_{A} molecules of BaCl_{2} produce 2N_{A}  molecules of AlCl_{3} (N_{A} is avogadro number).

We know 1 mol of molecule = N_{A} number of molecules.

So 3 moles of BaCl_{2} produce 2 moles of AlCl_{3}.

Hence 18.4 moles of BaCl_{2} produce (\frac{2}{3}\times 18.4) moles of AlCl_{3} or 12.3 moles of AlCl_{3} .

A chemist requires 0.802 mol Na2CO3 for a reaction. How many grams does this correspond to?
Komok [63]

Answer:

Ok:

Explanation:

So grams = mols*MolarMass. Here, MolarMass (MM) = 105.99g which can be found using the periodic table. mols is given to be 0.802. We can then plug in to get that it corresponds to 85.0g.

never [62]

Answer:

<em></em>(B) Carbon Dioxide<em></em>

Explanation:

Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen, with a lot of that in the form of water. The remaining 4 percent is a sparse sampling of the periodic table of elements

Hope this helps :)
