Ammonia, NH3, undergoes reaction with oxygen to form nitrogen and water. When 7.00 x 1022 molecules of ammonia react with 6.00 x 1022 molecules of oxygen, what mass of nitrogen results (grams)

Answers

Amount of nitrogen produced = 1.624 g

To calculate the moles, we use the equation:    

4NH3(g) + 3 O2 (g) ---> 2 N2 (g) + 6 H2O (g)                           ....(1)

For ammonia:

Putting values in above equation, we get:

Moles of ammonia = 7.00 x 1022 / 6.023 * 10 ^23 = 0.116 mol

Moles of oxygen = 6.00 x 1022 / 6.023 * 10 ^23 = 0.099 mol

For the reaction:

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

By Stoichiometry of the reaction,

4 moles of ammonia combine with 3 moles of Oxygen

Thus 0.116 moles of ammonia will combine with= 3/4 * 0.116 = 0.087 of oxygen

Thus ammonia is the limiting reagent as it limits the formation of product.

4 moles of ammonia produces 2 moles of nitrogen

0.132 moles of ammonia will produce=2/4 * 0.116 = 0.058 of nitrogen

Molar mass of nitrogen =  28 g/mol

Amount of nitrogen produced=

No of moles * molar mass = 0.058 * 282 = 1.624 g

Lead(II) oxide from an ore can be reduced to elemental lead by heating in a furnace with carbon. Calculate the expected yield of lead if 50.0 kg of lead oxide is heated with 50.0 kg of carbon.

Answers

Find the expected yield of lead:

The expected yield of lead if 50.0 kg of lead oxide is heated with 50.0 kg of carbon is 46 kg

Calculation:

First and foremost, we must correctly write the equation of reaction in order to answer this issue. This is what it is:

PbO(s) + C(s) → Pb(l) + CO (g)

We continue from here. The limiting reactant should be found, however finding out how many moles of each reactant are present is the only way to do so.

The number of moles is calculated using the formula: the mass of each reactant divided by the molar mass of each reactant.

Mass of PbO is 50kg = 50000g

Molar mass of PBO = 223.20g/mol

The number of moles is thus 50000/223.2 = 224 moles

For carbon, mass is also 50kg = 50000g

Molar mass is 12g/mol

Number of moles of carbon = 50000/12 = 4166.6 moles

We can observe from the number of moles that there are more moles of carbon than PbO. This indicates that the limiting reagent is PbO.

So, in order to determine percentage yield, we employ it.

Since we have a mole ratio of 1 to 1, the number of moles of lead created is equal to the number of moles of lead oxide, which is 224.

The molar mass of lead = 207.20 g/mol

The mass of lead formed = moles of lead x molar mass of lead

The mass of lead formed = 207.20 x 224 =  46,412.8 g = 46 kg

Hence, the expected yield is 46 kg.

What way did political policies act as a centrifugal force in the Soviet Union during the late 1980s ?

In the late 1980s, the economic and social situation in the Soviet Union was tense. The socialist economy was on the verge of collapse, the war in Afghanistan was an assured defeat, and the quality of life for Soviet citizens was appalling.

Due to these situations, the Soviet leader Mikhail Gorbachev decided to carry out a series of economic and political reforms, known as Perestroika and Glasnost, aimed at liberalizing the economy from a pure socialist model to a mixed model, and granting greater rights and civil liberties to the citizens.This led to numerous mobilizations and demonstrations, which further weakened the already weak Soviet political apparatus and made possible the emergence of regionalist nationalisms in the former Soviet nations, especially those subjugated to the power of Russia.

The percentage composition of an organic acid is found to be 39.9% C, 6.7% H, and 53.4% O. The molar mass for the compound is 60.0g/mol. What is the molecular formula

Answers

Answer:

C₂H₄O₂

Explanation:

To find the molecular formula of the organic acid, you need to (1) determine the mass of each element (from the given percents), then (2) convert grams of each element to moles (via atomic masses), then (3) find the empirical formula, and then (4) find the molecular formula.

(Step 1)

39.9% C -----> 39.9 g C

6.7% H -----> 6.7 g H

53.4% O -----> 53.4 g O

(Step 2)

Atomic Mass (C): 12.011 g/mol

Atomic Mass (H): 1.008 g/mol

Atomic Mass (O): 15.988 g/mol

39.9 grams C             1 mole
----------------------  x  ----------------------  = 3.32 moles C
                                12.011 grams

6.7 grams H              1 mole
--------------------  x  ---------------------  =  6.65 moles H
                              1.008 grams

53.4 grams O              1 mole
----------------------  x  ----------------------  =  3.34 moles O
                                15.998 grams

(Step 3)

The empirical formula is made up of the lowest possible amount of each element in the molecule. These amounts can be found by dividing the molar value of each element by the smallest molar value. In this case, the smallest molar value is 3.32 moles C. The calculated values make up the subscripts in the empirical formula.

3.32 moles C / 3.32  =  1 mole C

6.65 moles H / 3.32  =  2 moles H

3.34 moles O / 3.32  =  1 mole O

Empirical Formula: CH₂O

(Step 4)

To find the molecular formula, you first need to determine the molar mass of the empirical formula. Once you have this value, you need to determine how much you need to scale the formula up by. In this case, the molar mass of the empirical formula is half of the molar mass of the molecular formula. Therefore, you need to multiply the amount of each element in the molecule by 2.

Molar Mass (CH₂O): 12.011 g/mol + 2(1.008 g/mol) + 15.998 g/mol

Molar Mass (CH₂O): 30.025 g/mol

30.025 g/mol x 2 = 60.05 g/mol

CH₂O x 2 = C₂H₄O₂

Molecular weight and configurational stability of poly [(fluorophenyl) acetylene]s prepared with metathesis and insertion catalysts

Answers

A detailed article on formation of poly [(fluorophenyl) acetylene]s prepared with metathesis and insertion catalysts has been given below.

What is Molecular weight and configurational stability of poly [(fluorophenyl) acetylene]s?By polymerizing (2-fluorophenyl)acetylene, (3-fluorophenyl)acetylene, and (4-fluorophenyl)acetylene with catalysts [Rh(1,5-cyclooctadiene) OCH3]2, high-cis PFPhAs and tungsten(VI) oxychloride/tetraphenyltin, respectively, PFPhAs have been created.Size exclusion chromatography, 1H-NMR, and UV-vis methods were used to investigate the molecular weight and configurational stability of both PFPhAs series under varied circumstances at room temperature.The rate of degradation was independent of the F-position on the Ph ring for all samples while they were in the solid state and exposed to the environment. For high-cis polymers compared to their cis/trans counterparts, the rate of breakdown in the tetrahydrofuran solution increased by up to three orders of magnitude. In an aerated tetrahydrofuran solution, there was considerable cis-to-trans isomerization along with the degradation of high-cis PFPhAs.The F-position on the Ph ring showed the similar dependence on the rate of degradation and isomerization. It was proposed that cis-to-trans isomerization, which increases the amount of unpaired electrons on the main chains, hastened the degradation of high-cis PFPhAs in solution. The ortho-substituted isomers shown increased stability compared to the meta- and para-substituted isomers in both the high-cis and cis/trans series of polymers.
