2NO(g) + 5H2(g) ⟶ 2NH3(g) + 2H2O(g)If 45.4 grams of NO and 12.1 grams of H2 react, what is the largest amount of ammonia that can be formed? The final answer should be reported to one place after the decimal point
Answer:
25.8g of NH3 can be formed
Explanation:
To solve this question we must convert the mass of each reactant to moles using molar mass. With the chemical equation we can find limiting reactant. The moles of limiting reactant are used yo find the moles of ammonia produced and its mass:
Moles NO -30.01g/mol-
45.4g * (1mol / 30.01g) = 1.51 moles
Moles H2 -Molar mass: 2.01g/mol-
12.1g * (1mol / 2.01g) = 6.02 moles
For a complete reaction of 6.02 moles of H2 are needed:
6.02mol H2 * (2mol NO / 5mol H2) = 2.41 moles NO are needed
As there are just 1.51 moles, NO is limiting reactant
Moles NH3:
1.51 moles NO * (2mol NH3 / 2mol NO) = 1.51 moles NH3
Mass NH3 -Molar mass: 17.031g/mol-
1.51 moles NH3 * (17.031g / mol) =
25.8g of NH3 can be formedanswer 3 & 4

O structure should have 5 carbon with double bond beginning on the 2nd carbon atom
O structure should have 6 carbon with triple bond beginning on the 2nd carbon atom
O structure should have 6 carbon with double bond beginning on the 2nd carbon atom
O structure should have 5 carbon with triple bond beginning on the 2nd carbon atom
Answer:
The answer for 2-hexene is that the structure should have 6 carbon with a double bond beginning on the 2nd carbon atom.
The answer for 1-pentyne is that the structure should have 5 carbon with triple bond beginning on the 1st carbon atom.
Explanation:
2-Hexene
The structural formula for 2-hexene will have 6 carbons because the nomenclature has a -hex prefix, which stands for 6 carbons.
The -ene suffix of the nomenclature means that the organic compound is an alkene. Alkenes are hydrocarbons that contain double covalent bond and have the suffix -ene.
The double bond is on the 2 carbon atom because the nomenclature states that the double bond will be on the 2 carbon atom.
1-Pentyne
The structure will have 5 carbons since the -pent prefix means 5 carbons.
The structure has a triple bond because the -yne suffix means that the structure is an alkyne. An alkyne is a hydrocarbon with triple covalent bonds.
Also, the position of the triple bond is known because the nomenclature of the alkyne states that the triple bond is on the 1st carbon.

Answer:
La pregunta no es clara, asi que voy a dar una breve descripicion de la termodinamica y alguno de los fenomenos que estudia
La termodinámica es la rama de la física que estudia los sistemas en equilibrio termodinámico (es decir, aquellos sistemas que no pueden sufrir un cambio espontáneo). Particularmente, la termodinámica estudia los procesos de flujo de calor (lo podemos ver en su nombre, dinámica del calor) y se relacionan estos cambios de energía con el trabajo que es posible obtener.
Entonces, por ejemplo, la termodinámica estudia como el hielo puede cambiar de fase (a medida que aumenta su temperatura) y convertirse en agua líquida.
La termodinámica también estudia como funcionan máquinas de calor, como motores de pistones, y el trabajo que estos son capaces de realizar.
Como ejemplo final, con la termodinámica podemos estudiar cosas tan complejas como equilibrio entre distintas fases (por ejemplo, el porqué podemos tener agua y hielo en equilibrio termodinámico, un ejemplo de esto son las superficies de ríos que se congelan mientras la parte inferior sigue siendo líquida)
Esos son, entre muchísimos otros, 3 posibles efectos que suceden a nuestro alrededor, y son estudiados por la termodinámica.

Answer:
Explanation:
Sulfur trioxide, ammonia gas, and water will react to form ammonium sulfate. Determine the percent yield when 3.78 g of ammonium sulfate forms from the reaction of 2.51 g of sulfur trioxide, 1.55 g of ammonia, and 0.804 g of water. Can you please show step by step on how you got the answer thanks!
-
First, the balanced equation:
1 SO3 + 2 NH3 + 1 H2O --> 1 (NH4)2SO4
Find the limiting reactant using molar masses and mole ratios
2.51 g SO3 (1 mol SO3 / 80.06 g SO3) (1 mol (NH4)2SO4 / 1 mol SO3) = 0.03135 mol (NH4)2SO4
1.55 g NH3 (1 mol NH3 / 17.04 g NH3) (1 mol (NH4)2SO4 / 2 mol NH3) = 0.04548 mol (NH4)2SO4
0.804 g H2O (1 mol H2O / 18.02 g H2O) (1 mol (NH4)2SO4 / 1 mol H2O) = 0.04462 mol (NH4)2SO4
Therefore, the limiting reactant is sulfur trioxide.
Now find the theoretical yield of (NH4)2SO4.
2.51 g SO3 (1 mol SO3 / 80.06 g SO3) (1 mol (NH4)2SO4 / 1 mol SO3) (132.16 g (NH4)2SO3 / 1 mol (NH4)2SO4) = 4.14 g (NH4)2SO4
Actual yield / Theoretical yield x 100% = Percent yield.
Therefore, percent yield = 91.3%

Sulfur trioxide, ammonia gas, and water will react to form ammonium sulfate. Hence,the percent yield is 91.3%.
What is percent yield ?
The percentage yield displays the amount of product produced in relation to the maximum mass. The proportion of atoms in the reactants that go on to produce the intended product is determined by the reaction's atom economy.
The balanced chemical equation is as follows:
1 SO3 + 2 NH3 + 1 H2O ⇒ 1 (NH4)2SO4
Find the limiting reactant by using molar masses and mole ratios as follows:
2.51 g SO3 (1 mol SO3 / 80.06 g SO3) (1 mol (NH4)2SO4 / 1 mol SO3)
= 0.03135 mol (NH4)2SO4
1.55 g NH3 (1 mol NH3 / 17.04 g NH3) (1 mol (NH4)2SO4 / 2 mol NH3)
= 0.04548 mol (NH4)2SO4
0.804 g H2O (1 mol H2O / 18.02 g H2O) (1 mol (NH4)2SO4 / 1 mol H2O)
= 0.04462 mol (NH4)2SO4
Hence, the limiting reactant is sulfur trioxide.
Then, find the theoretical yield of (NH4)2SO4.
2.51 g SO3 (1 mol SO3 / 80.06 g SO3) (1 mol (NH4)2SO4 / 1 mol SO3) (132.16 g (NH4)2SO3 / 1 mol (NH4)2SO4)
= 4.14 g (NH4)2SO4
Actual yield / Theoretical yield x 100% = Percent yield.
percent yield = 91.3%
Thus, the percent yield is 91.3%.

13. +1
14. Cation
15. 5
16. 5
17. 2
18. Cation
Explanation:
Situation 1
The mass number = 35 = The sum of the protons and the neutrons in an atom
The number of protons = 17
The net charge = 1
3. The atomic number = The number of proton = 17
4. The number of neutrons = Mass number - Atomic number
∴ The number of neutrons = 35 - 17 = 18
5. Given that the net charge of the atom = +1, the number of electrons in the atom is 1 less than the number of protons
Therefore, the number of electrons = 11 - 1 = 10
6. Positively charged ions are called a cation
The atom is a positively charged and it is therefore it is a cation
Situation 2
The number of protons = 35
The number of neutrons = 46
The net charge = -1
7. The atomic number = The number of protons = 35
8. The mass number = The number of protons + The number of neutrons
∴ The mass number = 35 + 46 = 81
9. The number of electrons = The number of protons + 1
∴ The number of electrons = 35 + 1 = 36
10. The type of atom is an anion
Situation 3
Atomic number = 37
Mass number = 85
Number of electrons = 36
11. The number of protons = The atomic number = 37
12. The number of neutrons = The mass number - The atomic number
∴ The number of neutrons = 85 - 37 = 48
13. The net charge = The atomic number - The number of electrons
∴ The net charge = 37 - 36 = +1
14. Given that the net charge = +1, the type of atom is a cation
Situation 4
Mass number = 11
Number of neutrons = 6
Net charge = +3
15. The atomic number = The mass number - The number of neutrons
∴ The atomic number = 11 - 6 = 5
16. The number of protons = The atomic number = 5
17. Given that the net charge is +3, we have;
The number of electrons = The number of protons - The net charge
∴ The number of electrons = 5 - (+3) = 2
18. The type of atom with a net positive charge (+3) is a cation

If 12.3 g of Cu is deposited at the cathode of an electrolytic cell after 5.50 h, what was the current used?
Answer:
Current used = 1.90 A
Explanation:
The Faraday's first law of electrolysis states:
M = ZIt
where: M is the mass of the element deposited, Z is the electrochemical equivalence of the element, I is the amount of current required and t is the time taken.
From the given question, M = 12.3 g, t = 5.5 h (19800 s) and Z = 0.0003296 g/C.
So that,
12.3 = 0.0003296 x I x 19800
12.3 = 6.52608 I
I = [tex]\frac{12.3}{6.52608}[/tex]
= 1.88475
I = 1.90 A
The value of the current used used is 1.90 A
