A 5.0 L tank contains N2 at a pressure of 214 kPa. The gas is transferred to a second tank, where it’s pressure is measured at 148 kPa. What is the volume of the second tank

Answers

Answer 1

The volume of the second tank will be 7.2 L when the pressure is 148 kPa.

Boyle's Rule

Because the gas particles are compressed closer together as the pressure on a gas rises, the volume of the gas decreases. On the other hand, because the gas particles may now move further apart when the pressure on a gas lowers, the gas volume rises.

P 1 * V 1 = P 2 * V 2 can be used to calculate the pressure and volume of a given amount of gas at a fixed temperature.

P*V is a constant.

P stands for gas pressure.

V stands for gas volume.

P2 = 148 kPa

V2 = x

P1 = 214 kPa

V1 = 5.0 L

P1 * V1 = P2 * V2

214 * 5 = 148 * x

x = 7.2 L

V2= 7.2L

Given the following reaction:2 Li (s) + 2 H2O (I) = 2 LiOH (aq) + 1 H2 (g)How many grams of solid lithium must be used in this reaction in order to obtain 6.00 L of hydrogen gas at 1.10 atm and 25.0 C ?

Answers

Answer:

3.73 g of Li.

Explanation:

What is given?

Volume of hydrogen gas, H2 (V) = 6.00 L.

Pressure (P) = 1.10 atm.

Temperature (T) = 25.0°C + 273 = 298 K.

R = 0.082 L*atm/mol*K.

Step-by-step solution:

First, we have to find the number of moles of hydrogen gas (H2) using the ideal gas formula:

[tex]PV=nRT,[/tex]

where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant and T is the temperature on Kelvin scale. So let's solve for 'n' and replace the given values:

[tex]n=\frac{PV}{RT}=\frac{1.10\text{ atm}\cdot6.00\text{ L}}{0.082\text{ }\frac{L\cdot atm}{mol\cdot K}\cdot298K}=0.270\text{ moles.}[/tex]

Based on this, we have 0.270 moles of H2.

You can see in the chemical equation that 2 moles of Li reacted produce 1 mol of H2, so we have to state a rule of three:

[tex]\begin{gathered} 2\text{ moles Li}\rightarrow1\text{ mol H}_2 \\ ?\text{ moles Li}\rightarrow0.270\text{ moles H}_2 \end{gathered}[/tex]

The calculation will look like this:

[tex]0.270\text{ moles H}_2\cdot\frac{2\text{ moles Li}}{1\text{ mol H}_2}=0.540\text{ moles Li.}[/tex]

The final step is to convert 0.540 moles of Li to grams using its molar mass that can be found in the periodic table, which is 6.9 g/mol:

[tex]0.540\text{ moles Li}\cdot\frac{6.9\text{ g Li}}{1\text{ mol Li}}=3.73\text{ g Li.}[/tex]

The answer is that we must use 3.73 g of Li to produce 6.00 L of H2 at 1.10 atm and 25.0 °C.

A chemical equation is known to be balanced if the total number of moles of elements at the reactant is equal to that of the product.

For the reaction between sodium chloride (NaCl) and potassium nitrate (KNO₃), the balanced reaction is given as;

Given 20 grams of Na (s) and 10 grams of Cly, which reactant is in excess? And, how much NaCl should be produced from these amounts of the two reactants?

Answers

In order to answer this question we will need a few steps

First one will be to set up the properly balanced equation:

2 Na + Cl2 -> 2 NaCl

20 grams of Na

10 grams of Cl2

From this balanced equation we see that the molar ratio between Na and Cl2 is 2:1, that means that for every 2 moles of Na, we will need 1 mol of Cl2 in order to proceed with the reaction

Now we need to identify the limiting and excess reactant, we will do that by checking how many moles of each element we have and how much we should have in order to properly react with the other element, let's check it:

Molar mass for Na is 23g/mol

23g = 1 mol

20g = x moles

x = 0.89 moles of Na in 20 grams

So if we have 0.89 moles of Na, we should have 0.44 moles of Cl2, but we don't know if we have this amount of moles of Cl2 in 10 grams of it, let's check

Molar mass for Cl2 is 71g/mol

71g = 1 mol

10g = x moles

x = 0.14 moles

We have fewer moles than we actually needed, let's do the same step but now focusing on Cl2

Cl2 in 10 grams has 0.14 moles, therefore we will have 0.28 moles of Na, remember the molar ratio 2:1

23g = 1 mol

x grams = 0.28 moles

x = 6.44 grams of Na

If we have 10 grams of Cl2, we would only need 6.44 grams of Na, since we have more available, we can say that Na is in excess and Cl2 is the limiting reactant

To find out the mass of NaCl produced from 10 grams of Cl2 (we have to use the limiting reactant), NaCl has a molar mass of 58.44g/mol and the molar ratio will be again 2:1, one mol of Cl2 and 2 moles of NaCl, if we have 0.14 moles of Cl2, therefore we will have 0.28 moles of NaCl

58.44 g = 1 mol

x grams = 0.28 moles

x = 16.4 grams, the value in the options is a little higher, but not too much higher, that must be due some rounding up

Calcium reacts with Aluminum chloride to form Calcium chloride and Aluminum. If you react 100 grams of Aluminum chloride with Calcium, how many grams of Aluminum are produced?

Answers

38.95 g of Al is produced on reacting 100 g of Aluminium chloride with Calcium.

We need to write a balanced equation for the reaction. This is illustrated below:

2AlCl₃ + 3Ca —> 3CaCl₂ + 2Al

Molar Mass of AlCl₃

= 27 + (3x35.5)

= 27 + 106.5 = 133.5g/ mol

Mass of AlCl₃ from the balanced equation

= 2 x 133.5g

= 267g

Molar mass of Al= 26  

Mass of Al from balanced equation= 2×26

= 52

Molar Mass of CaCl₂ = 40 + (2 x 35.5)

= 40 + 71 = 111g/mol

Mass of CaCl₂ from the balanced equation

= 3 x 111 = 333g

From the equation,

133.5g of AlCl₃ produced 52g of Al

Therefore, 100g of AlCl₃ will produce

= (100 x 52)/133.5

= 38.95g of Al

So, 38.95 g of Al is produced on reacting 100 g of Aluminium chloride with calcium.

Answers

Answer:

A. 53.3% N, 46.7% O

Explanation:

1st) It is necessary to add both quantities (10.48g of nitrogen and 11.96g of oxygen) to obtain the total mass of the sample, which represents 100%:

10.48g + 11.96g = 22.44g

22.44g represents the 100% of the sample.

2nd) Now we can calculate the percentage composition of the gas, using a mathematical rule of three and the amount of nitrogen and oxygen:

• Nitrogen:

[tex]\begin{gathered} 22.44g-100\% \\ 10.48g-x=\frac{10.48g*100\%}{22.44g} \\ x=46.7\% \end{gathered}[/tex]

• Oxygen:

[tex]\begin{gathered} 22.44g-100\% \\ 11.96g-x=\frac{11.96g*100\%}{22.44g} \\ x=53.3\% \end{gathered}[/tex]

We can also calculate the oxygen percentage by subtracting 100% minus the nitrogen percentage (46.7%):

100% - 4607% = 53.3%

So, the percentage composition is 53.3% N and 46.7% O.

Which of the following combinations will form a solution?Group of answer choicesOil and waterSand and waterSugar and waterSand and sugar

Answers

Answer: the combination "sugar and water" will form a solution.

Explanation:

The question requires us to determine which of the combinations given will form a solution.

To solve this question, let's consider this definition of solution: a homogenous mixture of two or more substances in relative amounts. This means that, to be considered a solution, two mixed substances must form a homogeneous mixture, i.e., without separation of phases.

Considering the options given by the question, we can say:

- oil and water do not mix (because they have different polarities), and separate in different phases when are put together;

- sand and water do not form a homogeneous mixture: sand is deposited at the bottom of the vessel and forms a separated phase of solid;

- sugar and water can form a homogeneous mixture, therefore they form a solution;

- sand and sugar form visible separated phases when mixed together (we can see the particles of sugar and sand separated).

Therefore, considering the points above, we can say that only sugar and water form a solution.

For the following reaction, 0.156 moles of sulfuric acid are mixed with 0.567 moles of calcium hydroxide.

Answers

The first step is to write the reaction using the molecular formulas of the substances:

[tex]H_2SO_4+Ca(OH)_2\rightarrow CaSO_4+2H_2O[/tex]

Now that the equation is balanced, we have to divide the amount of each reactant by its stoichiometric coefficient, that in this case is 1 for both of them:

[tex]\begin{gathered} \frac{0.156mol}{1}=0.156mol \\ \frac{0.567mol}{1}=0.567mol \end{gathered}[/tex]

The least result will indicate the limiting reagent, which in this case is sulfuric acid. It means that its formula is H2SO4.

Basing our calculations in this reagent, we can find the maximum amount of calcium sulfate that is produced:

[tex]0.156molH_2SO_4\cdot\frac{1molCaSO_4}{1molH_2SO_4}=0.156molCaSO_4[/tex]

It means that the maximum amount of calcium sulfate that can be produced is 0.156 moles.

Given that

The number of moles of SeCl6 is 1.1 moles

Firstly, write a balanced equation of the reaction

[tex]\text{ SeCl}_6\text{ }\rightarrow\text{ Se + 3Cl}_2[/tex]

In the reaction above, 1 mole SeCl6 gives 3 moles Cl2

Let x be the number of moles of Cl2

[tex]\begin{gathered} \text{ 1 mole SeCl}_6\text{ }\rightarrow\text{ 3 moles Cl}_2 \\ \text{ 1.1 mole SeCl}_6\text{ }\rightarrow\text{ x moles Cl}_2 \\ \text{ cross multiply} \\ \text{ 1 mole SeCl}_6\times\text{ x moles Cl}_2\text{ = 1.1 mole SeCl}_6\text{ }\times\text{ 3 moles Cl}_2 \\ \text{ Isolate x } \\ \text{ x = }\frac{1.1moles\cancel{SeCl_6}\times\text{ 3 moles Cl}_2}{1mole\cancel{SeCl_6}} \\ \\ \text{ x = 1.1 }\times\text{ 3} \\ \text{ x = 3.3 moles} \end{gathered}[/tex]

Therefore, there are 3.3 moles of Cl2 in 1.1 moles of SeCl6

The Law of Conservation of Mass can be state in different ways. Essentially, this law states that if we are on a closed system, no mass can be created nor dstroyed. In chemical terms, this means that in a chemical reaction the number of atoms of each element has to be the same in the reactants and the products.
