SVEN [57.7K]

Answer:

Functional groups

Explanation:

A functional group refers to an atom or cluster of atoms that are covalently bonded to carbon and influence the behavior of organic compounds.

There are several functional groups in organic chemistry that determine the properties of organic compounds.

For instance, in the compound CH3CH2CH2CH2OH, the functional group is the -OH group. The chemical and physical properties of this compound is largely determined by this functional group.

Nitrogen dioxide is used industrially to produce nitric acid, but it contributes to acid rain and photochemical smog. What volum
Strike441 [17]

Answer:

35.41 L

Explanation:

Given, Volume of Copper = 4.84 cm³

Density = 8.95 g/cm³

Considering the expression for density as:

Density=\frac {Mass}{Volume}

So,

So, Mass= Density  Volume = 8.95 g/cm³  4.84 cm³ = 43.318 g

Mass of copper = 43.318 g

Molar mass of copper = 63.546 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{43.318\ g}{63.546\ g/mol}

Moles of copper = 0.6817 moles

Given, Volume of nitric acid solution = 227 mL = 227 cm³

Density = 1.42 g/cm³

Considering the expression for density as:

Density=\frac {Mass}{Volume}

So,

So, Mass= Density  Volume = 1.42 g/cm³  227 cm³ = 322.34 g

Also, Nitric acid is 68.0 % by mass. So,  

Mass of nitric acid = \frac {68}{100}\times 322.34\ g = 219.1912 g

Molar mass of nitric acid = 63.01 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{219.1912\ g}{63.01\ g/mol}

Moles of nitric acid = 3.4786 moles

According to the reaction,  

Cu_{(s)}+4HNO_3_{(aq)}\rightarrow Cu(NO_3)_2_{(aq)} + 2NO_2_{(g)} + 2H_2O_{(l)}

1 mole of copper react with 4 moles of nitric acid

Thus,  

0.6817 moles of copper react with 4*0.6817 moles of nitric acid

Moles of nitric acid required = 2.7268 moles

Available moles of nitric acid = 3.4786 moles

Limiting reagent is the one which is present in small amount. Thus, nitric acid is present in large amount, copper is the limiting reagent.

The formation of the product is governed by the limiting reagent. So,

1 mole of copper on reaction forms 2 moles of nitrogen dioxide

So,

0.6817 mole of copper on reaction forms 2*0.6817 moles of nitrogen dioxide

Moles of nitrogen dioxide = 1.3634 moles

Given:  

Pressure = 724 torr

The conversion of P(torr) to P(atm) is shown below:

P(torr)=\frac {1}{760}\times P(atm)

So,  

Pressure = 724 / 760 atm = 0.9526 atm

Temperature = 28.2 °C

The conversion of T( °C) to T(K) is shown below:

T(K) = T( °C) + 273.15  

So,  

T₁ = (28.2 + 273.15) K = 301.35 K  

Using ideal gas equation as:

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 0.0821 L.atm/K.mol

Applying the equation as:

0.9526 atm × V = 1.3634 mol × 0.0821 L.atm/K.mol × 301.35 K  

⇒V = 35.41 L

Students at Gonzaga University were attempting to make barium phosphate by precipitation when mixing solutions of barium chlorid
Solnce55 [7]

Answer:

Explanation:

3BaCl₂(aq)        +    2Na₃PO₄(aq)   =   Ba₃(PO₄)₂    +    6NaCl(aq)

3 x 208 g = 624 g    2 x 164 g = 328 g  

 328 g  of Na₃PO₄ reacts with 624 g of BaCl₂

.611 g  of Na₃PO₄ reacts with 624 x .611/328 g of BaCl₂

624 x .611/328 g = 1.16 g of BaCl₂

BaCl₂ available is .504 g which is less than required .

Hence BaCl₂ is limiting reagent .
