34 g of O2 are reacted with excess Cs, causing a production of 199 g of Cs2O. What is the percent yield of this
reaction?
2 Cs + O2 ---> Cs2O

Answers

Answer:

33.23 %

Explanation:

4 Cs + O₂ → 2Cs₂O

First we convert 34 g of O₂ into moles, using its molar mass:

34 g O₂ ÷ 32 g/mol = 1.0625 mol O₂

Then we convert O₂ moles into Cs₂O moles, using the stoichiometric coefficients of the balanced reaction:

1.0625 mol O₂ * [tex]\frac{2molCs_2O}{1molO_2}[/tex] = 2.125 mol Cs₂O

Now we convert 2.125 moles of Cs₂O into grams, using its molar mass:

2.125 mol Cs₂O * 281.81 g/mol = 598.85 g Cs₂O

598.85 g is the theoretical yield. Finally we proceed to calculate the percent yield:

199 / 598.85 * 100% = 33.23 %

Answer:

1. Temperature,  the average kinetic energy of particles, indicates how warm something is. Thermal energy, or the overall kinetic energy of the particles, indicates how a substance or material will transmit heat or chill something else.

2. A thermal expansion is a matter to change in volume in response to a change in temperature.

3. Heat is the form of energy that is transferred between systems or objects with different temperatures.

4. Air temperature near or over bodies of water is much different from that over land due to differences in the way water and land heat and cool. Properties that affect water temperature are transparency, ability to circulate, and specific heat.

5. Radiation is the transfer of heat energy through space by electromagnetic radiation.

6.  Radiation is natural and found everywhere, it comes from outer space, the air we breathe, and the earth we tread.

7. When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. The fluid above a hot surface expands, becomes less dense, and rises.

8. Convection currents in the Earth occur in the mantle

9. The fire's heat causes molecules in the pan to vibrate faster, making it hotter. These vibrating molecules collide with their neighboring molecules, making them also vibrate faster.

10. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface. Conduction directly affects air temperature only a few centimeters into the atmosphere.

Which factor contributes the most to the rates of diffusion and effusion between two gases in a mixture?
a)The size of the particles.
b)The molar mass of the particles.
c)The interactions between the particles.
d)The relative volume of the particles to each other.

Answers

Answer:

b)The molar mass of the particles.

Explanation:

The rate of effusion of a gas is inversely proportional to the square root of its molar mass (Graham's law), a relationship that closely approximates the rate of diffusion. As a result, light gases tend to diffuse and effuse much more rapidly than heavier gases.

Write a balanced nuclear equation for the beta decay of 234/90Th

Answers

The balanced nuclear equation for the beta decay of 234/90Th can be represented as follows: ^234/90Th --> ^234/91Pa + e^0/-1β

In this equation, the nucleus of thorium-234 (234/90Th) undergoes beta decay. During beta decay, a neutron within the nucleus is converted into a proton, resulting in the emission of an electron (beta particle). As a result, the thorium-234 nucleus is transformed into protactinium-234 (234/91Pa) by gaining one proton.

The beta particle emitted during the decay process is represented as e^0/-1β, where the superscript 0 denotes that the electron has no charge (neutral), and the subscript -1 indicates that the electron carries a negative charge of -1.

It is important to note that in a nuclear equation, the total atomic mass and atomic number on both sides of the equation must be equal to maintain a balanced equation and conserve mass and charge.

Calculate the number of molecules found in 35 g of Sodium Hydroxide?

Answers

Answer:

5.27*10^23 (rounded to 3 significant figures)

Explanation:

The amount of molecules in one mole of anything is equal to Avogadro's number: 6.022×10^23

To find the number of moles of NaOH in 35 grams of it, do 35 divided by the molar mass (39.997): 35/39.997=0.87506562 moles of NaOH

To find the number of molecules, multiply the moles of NaOH by Avogadro's number: 0.87506562×(6.022×10^23)=5.26964522*10^23

Answer:

5.27x10²³ molecules

Explanation:

In order to solve this problem we first convert 35 g of Sodium Hydroxide (NaOH) into moles, using its molar mass:

35 g ÷ 40 g/mol = 0.875 mol

Finally we convert 0.875 moles into number of molecules, using Avogadro's number:

0.875 mol * 6.023x10²³ molecules/mol = 5.27x10²³ molecules

Calculate the volume that will be occupied by
240 mL of hydrogen, measured at 360 mm Hg, when
the pressure is changed to 1080 mm Hg.

Answers

Answer:

80 mL

Explanation:

Step 1: Given data

Initial pressure of hydrogen (P₁): 360 mmHgInitial volume of hydrogen (V₁): 240 mLFinal pressure of hydrogen (P₂): 1080 mmHgFinal volume of hydrogen (V₂): ?

Step 2: Calculate the final volume of hydrogen

If we assume ideal behavior and constant temperature, we can calculate the final volume occupied by hydrogen using Boyle's law.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁/P₂

V₂ = 360 mmHg × 240 mL/1080 mmHg = 80 mL

A sample of O2 occupies 75 L at 1 atm. If the volume of the
sample doubles, what is the new pressure of Oz?

Answers

Answer:

the  new pressure of Oz is 0.5 atm

Explanation:

The computation of the new pressure of Oz is shown below:

Given that

Original pressure of O2 (P1) = 1 atm

And, the Original volume of oxygen O2 (V1) = 75L

Now

New pressure of O2 (P2) = ?

And, the New volume of O2 (V2) = 2V1  i.e

= (2 × 75L)

= 150L

Here we applied the Boyle's law formula  

P1V1 = P2V2

1 atm × 75L = P2 × 150L

75 atm × L = 150L ×P2

Now Divide both sides by 150L to get P2

75 atm × L ÷ 150L = 150L × P2 ÷ 150L

0.5 atm = P2

Hence, the  new pressure of Oz is 0.5 atm

Answers

The given question is incomplete. The complete question is:

Gallium (Ga, 69.723 g/mol) is a metalloid obtained from its salts during the smelting of ores of other elements, like Zinc. has broad applicability in the electronics industry. It is also used as a safe replacement for mercury in thermometers as it melts at 29.8 °C and has a heat of fusion of 5.59 kJ/mol. What is the entropy change of 22 g of gallium in J/K as it melts when placed on a surface at 29.8°C?

Answer: The entropy change of of gallium in as it melts when placed on a surface at  is 5.81 J/K

Explanation:

Latent heat of fusion is the amount of heat required to convert 1 mole of solid to liquid at atmospheric pressure.

Amount of heat required to melt 1 mole of Ga = 5.59 kJ

Mass of Ga given = 22 gram

Heat required to melt 69.723 g of Ga = 5.59 kJ

Thus Heat required to melt 22 g of Ga = [tex]\frac{5.59kJ}{69.723}\times 22=1.76kJ[/tex]

Temperature = [tex]29.8^0C=(273+29.8)kJ=302.8kJ[/tex]

Now entropy change = [tex]\frac{\text {heat of fusion}}{\text {temperature in K}}=\frac{1.76kJ}{302.8K}=0.00581kJ/mol=5.81J/K[/tex]

Thus the entropy change of of gallium in as it melts when placed on a surface at [tex]29.8^0C[/tex] is 5.81 J/K

At equilibrium at 700 K, there are 0.516 mol of H 2 present. At equilibrium, there are ________ mol of Br 2 present in the reaction vessel.

Answers

Answer: At equilibrium , there are 0.274 moles of [tex]Br_2[/tex]

Explanation:

Moles of  [tex]H_2[/tex] = 0.682 mole

Moles of  [tex]Br_2[/tex] = 0.440 mole

Volume of solution = 2.00 L

Initial concentration of [tex]H_2[/tex] = [tex]\frac{0.682}{2.00}=0.341 M[/tex]

Initial concentration of [tex]Br_2[/tex] =  [tex]\frac{0.440}{2.00}=0.220 M[/tex]

Equilibrium concentration of [tex]H_2[/tex] = [tex]\frac{0.516}{2.00}=0.258 M[/tex]

The given balanced equilibrium reaction is,

             [tex]H_2(g)+Br_2(g)\rightleftharpoons 2HBr(g)[/tex]

Initial conc.   0.341 M    0.220 M        0 M    

At eqm. conc.   (0.341-x) M   (0.220-x) M   (2x) M

Given : (0.341-x) M = 0.258 M

x= 0.083 M

Thus equilibrium concentartion of [tex]Br_2[/tex] = (0.220-0.083) M = 0.137 M

Thus moles of [tex]Br_2[/tex] at equilibrium = [tex]0.137M\times 2.00L=0.274mol[/tex]

At equilibrium , there are 0.274 moles of [tex]Br_2[/tex]
