Cupric oxide (CuO) and cuprous oxide (Cu2O) are the names of two oxides of copper.

Both Cupric oxide (CuO) and cuprous oxide are different from one another because of the presence of number of copper atom. In one compound, copper is bonded with oxygen in 1:1 form whereas in the other compound, the copper is bonded with 2:1 form.

So we can conclude that Cupric oxide (CuO) and cuprous oxide (Cu2O) are the names of two oxides of copper.

Taking into account definition of percent yield, the percent yield for the reaction is 100%.

In first place, the balanced reaction is:

2 FeBr₃ + 3 Na₂S → Fе₂S₃ + 6 NaBr

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

The following rule of three can be applied: if by reaction stoichiometry 2 moles of FeBr₃ form 6 moles of NaBr, 2.36 moles of FeBr₃ form how many moles of NaBr?

[tex]moles of NaBr=\frac{2.36 moles of FeBr_{3}x6 moles of NaBr }{2 moles of FeBr_{3}}[/tex]

moles of NaBr= 7.08 moles

Then, 7.08 moles of NaBr can be produced from 2.36 moles of FeBr₃.

The percent yield is the ratio of the actual return to the theoretical return expressed as a percentage.

The percent yield is calculated as the experimental yield divided by the theoretical yield multiplied by 100%:

[tex]percent yield=\frac{actual yield}{theorical yield}x100[/tex]

where the theoretical yield is the amount of product acquired through the complete conversion of all reagents in the final product, that is, it is the maximum amount of product that could be formed from the given amounts of reagents.

In this case, being the molar mass of NaBr 102.9 g/mole, you know:

Replacing in the definition of percent yields:

[tex]percent yield=\frac{728.532 grams}{728.532 grams}x100[/tex]

Solving:

percent yield= 100%

Finally, the percent yield for the reaction is 100%.

Yes, an electron cause an electromagnetic wave to vibrate.

One of the waves is propagated by simultaneous periodic variations of electric and magnetic field intensity and that includes radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Electromagnetic waves are produced when something vibrates—an electric charge that moves back and forth.

When an electric charge vibrates, the electric field around it changes. Because the electric charge is in motion, it also has a magnetic field around it.

This magnetic field also changes as the charge vibrates.

Therefore, an electron causes an electromagnetic wave to vibrate.

They're going to fall apart.

A system's entropy cannot decrease unless heat is being lost from it. This indicates that entropy cannot decrease in a closed system (i.e., nothing enters or leaves, and that means nothing at all), so it must either remain constant or rise. Entropy can decrease, rise, or stay constant in an open system when movement between the system and its surroundings is conceivable. Both of these outcomes leave open the option of a constant state.

Entropy:-

The quantity of atom-alignment combinations that can exist in a system is known as entropy. The quantity of energy that cannot be used for work can also be calculated from an object's entropy.

1.5 moles of [tex]O_{2}[/tex] gas

Reaction of Al with [tex]O_{2}[/tex] to form [tex]Al_{2} O_{3}[/tex] is given below...

2 Al + 1.5 [tex]O_{2}[/tex] → [tex]Al_{2} O_{3}[/tex]

Here, 2 moles of Aluminum reacts with 1.5 moles of [tex]O_{2}[/tex]

atomic weight of aluminum = 27 g / mole

so, 1 mole of aluminum contains 27 g

then how many moles are there if it has 54 g in it.

moles of aluminum in 54 g = 54/27 = 2 moles

As per the equation mentioned above,

2 moles of aluminum reacts with 1.5 moles of [tex]O_{2}[/tex].

Answer:

4 NH₃ (g) + 3 O₂ (g) ----> 2 N₂ (g) + 6 H₂O (g) + energy

Explanation:

The unbalanced equation:

NH₃ (g) + O₂ (g) ----> N₂ (g) + H₂O (g) + energy

Reactants: 1 nitrogen, 3 hydrogen, 2 oxygen

Products: 2 nitrogen, 2 hydrogen, 1 oxygen

The sort-of balanced equation

2 NH₃ (g) + 1/2 O₂ (g) ----> N₂ (g) + 3 H₂O (g) + energy

I first started by balancing the nitrogens. This then lead me to balance the hydrogens. When I went to balance the oxygens, only a 1/2 coefficient would work. However, 1/2 coefficients are technically incorrect. To get rid of this coefficient, you need to multiply each coefficient by 2.

The balanced equation:

4 NH₃ (g) + 3 O₂ (g) ----> 2 N₂ (g) + 6 H₂O (g) + energy

Reactants: 4 nitrogen, 12 hydrogen, 6 oxygen

Products: 4 nitrogen, 12 hydrogen, 6 oxygen

Now, all of the elements are equal on both sides and there are no 1/2 coefficients. These are the smallest whole-number coefficients because some of the numbers cannot be further simplified (3).

The H₂ gas are needed 0.157moles to fill the bag .

For solving this problem  we use the ideal gas equation. It is also called the general gas equation . This equation use for a hypothetical ideal gas. . It has several limitations. It was first stated by Benoit Paul Emile Clapeyron in 1834 . The ideal gas law is  written by an empirical form:

                                  PV = n R T

where-

            P = Pressure

            V = volume

            T = Temperature

            n =  The amount of substance

            R =  Ideal gas constant

Now we have the values of these terms as-

             P = 1 atm , V = 3.79L ,  T = 293K

 and     R = 0.0826 L/atm

For getting moles of hydrogen we can use the values of variables in ideal gas equation as -

                     P V = n R T

Now              (1 atm) × ( 3.79L ) = n ×  ( 0.0826 L/atm)  × ( 293K)

                                            n = (1 × 3.79) ÷ (0.0826 x 293)

                                              =  0.157 moles

So that the 0.157moles of H₂ gas are needed for fill the bag .

Number 2 represents this process on the hydrologic cycle diagram. Therefore, the correct option is option B.

One of the most significant natural processes is the hydrologic cycle, which we may often take for granted. This process causes the water in the entire earth to change forms, locations, or accessibility.

Water transitions between three distinct forms during this cycle, to put it simply. It can be found in many states of liquid, gas, or solid, including ice, steam, and water. Water will frequently transition between these three states throughout the cycle: freezing into ice, melting into water, evaporating becoming water vapor, but finally condensing back into water. Number 2 represents this process on the hydrologic cycle diagram.

Therefore, the correct option is option B.
