A tank consists of a gaseous mixture of 3.83 g of triselenium diiodide, 2.62 g of ammonium telluride, and 1.82 g of iridium (i) sulfate. What is the partial pressure in atm of ammonium telluride if the total pressure in the tank is 2.795 atm?

Answers

Answer: The partial pressure in atm of ammonium telluride is 1.48 atm

Explanation:

According to Raoult's law, the partail pressure of a component at a given temperature is equal to the mole fraction of that component multiplied by the total pressure

[tex]p_A=x\times p_{total}[/tex]  

where, x = mole fraction

[tex]p_A[/tex] = partial pressure of A

[tex]p_{total}[/tex] = total pressure  

[tex]x_{\text {ammonium telluride}}=\frac{\text {moles of ammonium telluride}}{\text {total moles}}[/tex],  

[tex]x_{\text {ammonium telluride}}=\frac{\frac{2.62g}{164g/mol}}{\frac{2.62g}{164g/mol}+\frac{3.83g}{333g/mol}+\frac{1.82g}{673g/mol}}=0.53[/tex]

[tex]p_{\text {ammonium telluride}}=0.53\times 2.795atm=1.481atm[/tex]

Thus the partial pressure in atm of ammonium telluride is 1.48 atm

How many grams of NaCl is needed to make 750mL of a 2.4 M NaCl solution?

Answers

Answer:

Molarity of the solution = 3.000 M

Volume of the solution = 250.0 mL = 0.25 L

moles in 250.0 mL = molarity x volume of the solution

                             = 3.000 M x 0.25 L

                             = 0.75 mol

Hence, 0.75 mol of NaCl is needed to prepare 250.0 mL of 3.000 M NaCl solution.

Moles (mol) = mass (g) / molar mass (g/mol)

Moles of NaCl in 250.0 mL = 0.75 mol

Molar mass of NaCl           = 58.44 g/mol

Mass of NaCl in 250.0 mL = Moles x Molar mass

                                         = 0.75 mol x 58.44 g/mol

                                         = 43.83 g

Hence, 43.83 g of NaCl is needed to prepare 250.0 mL of 3.000 M solution.

What are the units for the measurements of radioactive element activity?

Answers

Answer:

Bq

Explanation:

The number of decays per second, or activity, from a sample of radioactive nuclei is measured in becquerel (Bq), after Henri Becquerel. One decay per second equals one becquerel.

The radioactive decay has been measured as decay per second by becquerel (Bq).

Radioactive decay has been given as the loss of energy by the nucleus. The release of energy has been in the form of radiation. The varying energy radiations have been termed alpha decay, beta decay, gamma decay.

The decay has been performed by unstable nuclei with the emission of multiple particles. The decay unit has been given by Henri Becquerel. The unit has been the determination of the decay performed per second and has been given by becquerel (Bq).

Thus, the unit for the measurement of radioactive decay has been becquerel (Bq).

extremely hot.When a student went to open the car doo , he burned his finger. What two forms of energy were responsible for the student burning his fingers

Answers

Answer:

radiation and conduction

Explanation:

During a warm summer day, a car became extremely hot. When a student went to open the car door, he burned his fingers. What two forms of energy were responsible for the student burning his fingers?

Solution:

Heat is the transfer of energy from a warmer object to a cooler object. For heat transfer to occur, there have to be a difference in temperature between two objects.  

Heat can be transferred in three ways: by conduction, by convection, and by radiation.

Conduction is the transfer of thermal energy between bodies through direct contact. Convection is the transfer of thermal energy through the movement of heat in a liquid or gas. Radiation is the transfer of thermal energy through thermal emission by electromagnetic waves.

During a warm summer day, The sun makes the car to become hot through energy transfer from the sun to the car. When the student touch the car, there is heat transfer as a result of conduction.

9.32 L of pentane reacts with 36.4 L of oxygen. how many liters of carbon dioxide are formed?

Answers

Answer:

22.75 L CO2

Explanation:

Balance the Equation

C5H12  +  O2 ==>   CO2 + H2O        Balance the Carbons

C5H12  +  O2 ==>   5CO2 + H2O     Now balance the Hydrogens

C5H12  +  O2 ==>   5CO2 + 6H2O   Now count up the oxygens on the right.

5*O2 + 6O ==> 10 O + 6 O ===> 16 Oxygens.

You have 2 on the left. You have to multiply the oxygens by 8

C5H12  +  8O2 ==>   5CO2 + 6 H2O

The equation is now balanced.

Now find out how much oxygen is needed to burn 9.32 L of Pentane

1 Liter Pentane / 8 Liters Oxygen = 9.32 L Pentane / x     Cross multiply

x = 8 * 9.32

x = 74.56

Read this next sentence very carefully. You need 74.56 Liters of oxygen to burn all the pentane you have. There's not that much there. You only have 36.4 Liters of Oxygen. Some of the pentane won't get burned. Consequently there will be a shortage of CO2 as well.

Find out the number of Liters of Pentane that will be burned up.

1 / x =  8 / 36.4               Cross multiply

8x = 36.4                        Divide by 8

8x/8 = 36.4/8

x = 4.55 Liters of Pentane will be  used up.

Find the number of Liters of CO2

For every Liter of Pentane, 5 Liters of CO2 will be produced.

1/5 = 4.55/x                      Cross Multiply

x = 5 * 4.55

x = 22.75

¿Cuántos gramos de dicloruro de manganeso se obtienen cuando reaccionan 7,5 g de ácido clorhídrico? MnO2 + 4 HCl = Mn Cl2 + Cl2 + 2 H2O *

Answers

Answer:

6.6 g

Explanation:

La ecuación de la reacción es;

MnO2 + 4 HCl -------> MnCl2 + Cl2 + 2H2O

Número de moles de HCl que reaccionan = 7.5g / 36.5 g / mol = 0.21 moles

Dado que;

4 moles de HCl producen 1 mol de MnCl2

0,21 moles de HCl producen 0,21 * 1/4 = 0,0525 moles de MnCl2.

Masa de MnCl2 = 125,844 g / mol * 0,0525 moles = 6.6 g
