Answers

The one that does not demonstrates the law of conservation of matter would be the third option: [tex]2NO_2 + H_2O -- > HNO_3 + HNO_2[/tex]

What is law of conservation of matter?

It is a law that explains that matters are conserved during the course of chemical reactions. They can neither be destroyed nor created.

Thus, the number of moles of the species in a reaction remains the same before and after the reaction.

Thus, an equation that demonstrates the law of conservation of matter will be balanced in terms of the number of moles of species.

The only equation, in this case, is [tex]2NO_2 + H_2O -- > HNO_3 + HNO_2[/tex]

There are 3 oxygen species on the reactant while 5 are present on the product side.

What is an ideal gas equation?

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Given:

[tex]C(s) + O_2(g)[/tex] ⇒[tex]CO_2(g)[/tex]

1 mole of [tex]CO_2(g)[/tex] is formed from 1 mole of charcoal, that means 1 mole of [tex]CO_2(g)[/tex] is formed from 12 g of charcoal.

1 lbs = 453.592 grams

6.75 lbs = 6.75 x 453.592 =3061.746g

So, [tex]CO_2(g)[/tex] formed from 3061.746g of charcoal is:

=[tex]\frac{1}{12}[/tex] x 3061.746g

=255.14 mol.

Now, at STP, the volume of 1 mol of gas =22.4 L

Volume of 255.14 mol of [tex]CO_2(g)[/tex] = 255.14 x 22.4 L

Volume of 255.14 mol of [tex]CO_2(g)[/tex] = 535.8 L

Hence, 535.8 L volume(in L), at STP, of carbon dioxide produced by the complete combustion of 6.75 lbs of charcoal.

Answers

0.448 moles of ions will form when a 42.66-gram sample of magnesium chloride is dissolved in water (option A).

How to calculate number of moles?

According to this question, when magnesium chloride (MgCl2) dissolves in water, it dissociates into magnesium ions and chloride ions as follows:

MgCl2(aq) ⟶ Mg2+(aq) + Cl−(aq)

However, if a 42.66-gram sample of magnesium chloride is dissolved in water, this means that 42.66g/molecular mass of MgCl2 will be the number of moles of the ionic products.

molecular mass of MgCl2 = 95.3g/mol

Explanation:

P1 V1 /T1 = P2 V2 / T2              T   must be in Kelvin

re-rrange to :

P1 V1 / T1  *  T2/V2  = P2

2.81 * 713 / (664)  *  368 /126  = 8.81 atm

The new pressure of the gas given that its volume and temperature change to 126 L and 368 K respectively is 8.81 atm

Data obtained from the question Initial pressure (P₁) = 2.81 atmInitial volume (V₁) = 713 L Initial temperature (T₁) = 664 K New Volume (V₂) = 126 L New temperature (T₂) = 368 KNew pressure (P₂) = ?

How to determine the new pressure

The new pressure of the gas can be obtained by using the combined gas equation as illustrated below:

P₁V₁ / T₁ = P₂V₂ / T₂

(2.81 × 713) / 664 = (P₂ × 126) / 368

Cross multiply

664 × 126 × P₂ = 2.81 × 713 × 368

Divide both side by 664 × 126

P₂ = (2.81 × 713 × 368) / (664 × 126)

3750 J of heat were added to sample of magnesium with an unknown mass. If the temperature ofthe sample increased by 23 °C, what is the mass of the sample? (The specific heat of magnesium is 1.02 J/g. Celsius.

Answers

Taking into account the definition of calorimetry, the mass of the sample is 159.85 grams.

What is calorimetry

In first place, calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

In this way, between heat and temperature there is a direct proportional relationship (Two magnitudes are directly proportional when there is a constant so that when one of the magnitudes increases, the other also decreases; and the same happens when either of the two decreases .).

The constant of proportionality depends on the substance that constitutes the body and its mass, and is the product of the specific heat by the mass of the body.

So, the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where:

Q is the heat exchanged by a body of mass m.c is the specific heat substance.ΔT is the temperature variation.

Mass of the sample

In this case:

Q= 3750 Jc= 1.02[tex]\frac{J}{gC}[/tex]m= ?ΔT= 23 C

Replacing in the expression to calculate heat exchanges:

3750 J= 1.02 [tex]\frac{J}{gC}[/tex]× m× 23 C

Solving:

m= 3750 J ÷ (1.02 [tex]\frac{J}{gC}[/tex]× 23 C)

m= 159.85 grams

In summary, the mass of the sample is 159.85 grams.

Adding more of gas C to the system
Heating the system

Removing some of gas C from the system

Answers

Answer:

A.) Adding more of gas C to the system

Explanation:

A.) is correct because the reaction wants to keep the same amount of reactants and products that sustain equilibrium. If you are increasing the amount of gas C, this will push the reaction to make more of the reactants to restore the balance.

B.) is incorrect because heat is a form of energy. As previously stated, when you add more material to the reactants side, the equilibrium shifts to the product side to restore equilibrium.

C.) is incorrect because when the volume is increased, the equilibrium will shift to the side with the greater amount of moles of gas. There is 1 mole of gas on the reactant side (from A (g)) and 3 moles of gas on the products side (from 3 C (g)). Therefore, the reaction will shift to the product side.

D.) is incorrect because if the material on the product side is decreasing, the equilibrium will want to make up that difference by shifting to the product side.

Answers

Answer:

52.6 g C₆H₆O₂

Explanation:

Unfortunately, the problem does not specify which of the reactants is the limiting reagent. This means you must convert both starting amounts into the product to identify the final answer.

To find the mass of hydroquinone (C₆H₆O₂) produced, you need to (1) calculate the molar masses of the reactants and product, then (2) convert grams of the reactants to grams of the product (via the molar masses and the mole-to-mole ratio from equation coefficients), and then (3) determine the limiting reagent and the actual answer.

(Step 1)

Molar Mass (C₆H₅OH): 6(12.011 g/mol) + 6(1.008 g/mol) + 15.998 g/mol

Molar Mass (C₆H₅OH): 94.112 g/mol

Molar Mass (H₂O₂): 2(1.008 g/mol) + 2(15.998 g/mol)

Molar Mass (H₂O₂): 34.012 g/mol

Molar Mass (C₆H₆O₂): 6(12.011 g/mol) + 6(1.008 g/mol) + 2(15.998 g/mol)

Molar Mass (C₆H₆O₂): 110.11 g/mol

(Step 2)

It is important to arrange the ratios/conversions in a way that allows for the cancellation of units (the desired unit should be in the numerator). The final answer should have 3 sig figs to reflect the sig figs of the given values.

45.0 g C₆H₅OH             1 g              1 mole C₆H₆O₂             110.11 g
------------------------  x  --------------  x  -------------------------  x  -----------------  =
                                  94.112 g         1 mole C₆H₅OH            1 mole

 

=  52.6 g C₆H₆O₂

20.0 g H₂O₂           1 mole             1 mole C₆H₆O₂           110.11 g
-------------------  x  -----------------  x  -------------------------  x  ---------------  =
                              34.012 g              1 mole H₂O₂            1 mole

=  64.7 g H₂O₂

(Step 3)

The limiting reagent of the reaction is C₆H₅OH because it is not able to produce as much product as H₂O₂. As such, product stops being made as C₆H₅OH runs out, making the final amount 52.6 g C₆H₆O₂.

Answer:

See below

Explanation:

Mole weight of C6H5OH  = 94 gm/mole       (approx)

   45 gm / 94 gm/mole = .479 Moles of phenol

Mole wt of H2O2  = 34        (approx)

    20 gm / 34 gm /mole = .588 moles of hydrogen peroxide

From the equation.....it takes equal moles of these to react to produce the same number of moles of hydroquinone.....

  there isn't enough phenol to match the peroxide....so phenol is limiting reactant and you will only get .479 moles of hydroquinone

hydroquinone mole weight = 110 gm / mole       (approx)

    .479 mole * 110 gm/mole = 52.69 gm produced

The volume of water vapour gas that would be produced will be 2,581.73 L

Stoichiometric calculations

From the equation of the reaction, the mole ratio of propane to oxygen is 1:5.

Mole of 535.55 grams of propane = 535.55/44.1 = 12.12 moles

Mole of 2665.06 grams of oxygen = 2665.06/32 = 83.28 moles

Going by the mole ratio, it appears propane is limiting while oxygen is in excess.

From the equation, 1 mole of propane produces 4 moles of water vapour. Thus, the equivalent mole of water vapour will be:

12.12 x 4 = 48.48 moles.

Using the ideal gas equation: pv = nRt

v = nRT/p = 48.48 x 0.08206 x 623/0.96 = 2,581.73 L
