Answer:

Wetlands are from being useless, disease-ridden places, wetlands provide values that no other ecosystem can. These include natural water quality improvement, flood protection, shoreline erosion control, opportunities for recreation and aesthetic appreciation and natural products for our use at no cost. Removal of the wetlands can result in fish disease, dominance of acid-tolerant species, contamination of groundwater, reduction in agricultural productivity and damage to infrastructure through corrosion. The loss of the wetlands introduces invasive species, either intentionally or unintentionally, these species can put pressure on native plants and eventually push them out of their native habitat.

Removal of the wetlands can result in fish disease, the dominance of acid-tolerant species, contamination of groundwater, reduction in agricultural productivity, and damage to infrastructure through corrosion.

In the last three decades alone, nearly one-third of natural wetlands have been lost to urbanization, agriculture expansion, and pollution. The loss of wetlands in urban areas has been more rapid.

[tex]1.409 \times {10}^{24} \: \: atoms[/tex]

Explanation:

Convert from moles to atoms:

2.34 mol titanium (Ti)

Determine the amount of substance, n:

n = 2.34 mol

Look up Avogadro's constant, [tex] N_A[/tex] , to find the number of atoms in a mole:

[tex] N_A[/tex] = 6.022×10^23 atoms/mol

Multiply n by [tex] N_A[/tex] to convert to the number of atoms, [tex]N_{atoms}[/tex]:

Precise Answer:

[tex] N_{atoms} [/tex] = n× [tex] N_A [/tex]= (2.34 mol)/1×(6.022×10^23 atoms)/(1 mol) = 1.409×10^24 atoms

N₂O₅ + H₂O --> 2HNO₃

This reaction is a combination reaction

Explanation:

I find that making a table is an easy way to balance a table. The table would be something like this:

Reactants (left) Products (right)

N = 2 N = 1

O = 6 O = 3

H = 2 H = 1

The number next the symbol represents how many of atoms of that particular element are present.

The aim is to make the number of atoms of each element on the left side to be equal to the number of atoms of each element on the right side. As we can see, there are 1 more nitrogen than on the right, 3 more oxygen than on the right and 1 more hydrogen than on the left.

So to make the numbers of atoms of each element on right equal to the number of atoms of each element on the left, we have to add a number. This number CANNOT be a subscript number because that would change the reaction.

We can add a 2 in front of the product (this is because there are less atoms in the right side of the equation).

N₂O₅ + H₂O --> 2HNO₃

This means there are now two HNO₃ molecules so every atom in this molecule is basically multiplied by 2. So 1 nitrogen atom becomes two (1 × 2 = 2), 3 oxygen atoms become 6 (3 × 2 = 6) and 1 hydrogen atom becomes 2 (1 × 2 = 2). If we were to make a table again with the following equation - N₂O₅ + H₂O --> 2HNO₃, the table would be as so:

Reactants (left) Products (right)

N = 2 N = 2

O = 6 O = 6

H = 2 H = 2

Now the equation is balanced as we can see the number each type of atom is the same on the right and left side.

Answer:

28.5 g NH₃

Explanation:

You can determine how much ammonia will form by identifying which reactant is the limiting reagent. This can be done by converting each reactant into moles, using the mole-to-mole ratio (after balancing the reaction), then converting ammonia to grams.

2 NO + 3 H₂ --> 2 NH₃ + O₂

Molar Mass (NO) = 14.01 + 16.00 = 30.01 g/mol

Molar Mass (H₂) = 2(1.008) = 2.016 g/mol

Molar Mass (NH₃) = 14.01 + 3 (1.008) = 17.034 g/mol

50.2 g NO          1 mol             2 mol NH₃            17.034 g
----------------  x  ---------------  x  --------------------  x  ----------------  =  28.5 g NH₃
                          30.01 g           2 mol NO              1 mol

15.1 g H₂             1 mol             2 mol NH₃            17.034 g
----------------  x  ---------------  x  --------------------  x  ----------------  =  85.1 g NH₃
                          2.016 g           3 mol H₂                 1 mol

Nitrogen oxide (NO) is the limiting reagent because it produces the smallest amount of product. In other words, it runs out before all of the hydrogen gas (H₂) can be used. This means that the largest amount of ammonia that can be produced is 28.5 grams.

The material which requires the most heat to raise its temperature from 10°C to 30°C is oil.

The formula which we used to calculate the amount of involved heat in relation with specific heat is:

Q = mcΔT, where

Among the given materials, specific heat of oil is highest than other materials so will require maximum absorbed heat.

Hence, oil requires the most heat.

The products obtained when Calcium Carbonate reacts with Silver Sulfate  is Calcium Sulfate and Silver Carbonate , CaSO₄ + Ag₂CO₃

The reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions.

Many double displacement reactions occur between ionic compounds that are dissolved in water.

In a double displacement reaction, atoms from two different compounds switch places.

The reactants are two compounds and the products are two different compounds.

The reaction given below is an example of Double Dispalcement Reaction

CaCO₃ + Ag₂SO₄ → CaSO₄ + Ag₂CO₃

1 mole of Calcium Carbonate reacts with Silver Sulfate  to form  1 mole of Calcium Sulfate and Silver Carbonate , CaSO₄ + Ag₂CO₃.

Answer:

6.25 L

Explanation:

Boyle's law says Pressure and volume are inversely related. One goes up and other goes down (vice versa).

P1 V1 = P2 V2

(2.5) (1) = (0.4) (x)

x= 6.25 L

The answer should make sense because your pressure went from high to low which means your volume should opposite, from low to high, and that's what we see.

Answer:

There are 20. mol of Na2CO3 in 10.0L of 2.0M solution.

Explanation:

Molarity is represented by this equation:

(look at attachment)

In our case, we already have the molarity and volume of solution, both of which have good units.

Let's rearrange the equation to solve for the number of moles. We can do this by multiplying by L solution on both sides of the equation. The L solution will cancel out on the right side, leaving the number of moles being equal to the molarity times volume:

Moles of solute

=Lsolution×Molarity

Now we just plug the known values in!

Moles of solute = (10.0 L) (2.0M) = 20. moles

A transformation of chemical energy to electrical energy occurs when there is a chemical reaction between metals and nonmetals.

The movement of electrons from one atom to another is what results in electrical energy.

A battery is a device that converts chemical energy contained within its active materials directly into electric energy by means of an electrochemical oxidation-reduction (redox) reaction. This type of reaction involves the transfer of electrons from one material to another via an electric circuit.
