Which of the following answer describes 2-hexene? *
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.
Write a balanced nuclear equation for the alpha decay of titanium-45.
Explanation:
20984Po→20582Pb+42α
4520Ca→4521Sc+0-1e+00ν
Explanation:
The alpha decay of polonum-209, which consists of the emission of an alpha particle, will leave behind the atom of a different element.
Notice that the identity of the element changes after the decay. This means that you're dealing with a nuclear transmutation, a process that converts an atom of a given element into an atom of a different element.
A chemical reaction done at STP conditions is supposed to produce 0.011 moles of CO2 gas. How many liters of gas will that be?
Answer:
V = 0.24 L.
Explanation:
Hello there!
In this case, it is possible to approach this problem by using the ideal gas equation defined by:
[tex]PV=nRT[/tex]
Whereas our unknown is V, volume, and we solve for it as follows:
[tex]V=\frac{nRT}{P}[/tex]
Then since the STP conditions are ate 273.15 K and 1 atm, the volume of 0.011 moles of CO2 gas turns out to be:
[tex]V=\frac{0.011mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}\\\\V=0.24L[/tex]

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.
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

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%.

= 3.01 × 10^24 atoms of vitamin D
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) =

Answer: The volume of stock solution needed is 62.5 mL
Explanation:
A solution consists of solute and solvent. A solute is defined as the component that is present in a smaller proportion while the solvent is defined as the component that is present in a larger proportion.
To calculate the volume of stock solution needed, the formula used is:
[tex]C_1V_1=C_2V_2[/tex] ....(1)
where,
[tex]C_1\text{ and }V_1[/tex] are the concentration and volume of stock solution.
[tex]C_2\text{ and }V_2[/tex] are the concentration and volume of diluted solution.
We are given:
[tex]C_1=3.00M\\V_1=?mL\\C_2=1.25M\\V_2=150mL[/tex]
Putting values in equation 1, we get:
[tex]3.00\times V_1=1.25\times 150\\\\V_1=\frac{1.25\times 150}{3.00}\\\\V_1=62.5mL[/tex]
Hence, the volume of stock solution needed is 62.5 mL

Sodium reacts with chlorine to form sodium chloride. Which statements describe what happens to the sodium atoms in this reaction? 1. Sodium atoms form positive ions. 2. Sodium atoms form negative ions. 3. Sodium atoms gain electrons. 4. Sodium atoms lose electrons a. 1 and 3 b. 1 and 4 c. 2 and 3 d. 2 and 4
Answer: The correct option is b) 1 and 4.
Explanation:
An ionic compound is formed when a complete transfer of electrons takes place from one element (usually metals) to another element (usually non-metals).
The element (metal) that loses electrons forms a positive ion which is known as cation while the element (non-metal) that gains electrons forms a negative ion which is known as an anion.
Sodium chloride is an ionic compound that is formed by the combination of sodium and chloride ions.
Sodium is the 11th element of periodic table having electronic configuration of [tex]1s^22s^22p^63s^1[/tex]
It will lose 1 electron to form a positive in having a chemical formula of [tex]Na^+[/tex]
Therefore, the statements that say, sodium atoms form positive ions and sodium atoms will lose electrons are correct.
Thus, the correct option is b) 1 and 4.

Answer:

Explanation:
The molarity of the HCl solution is 5M and the correct option is option C.
What is Molarity?Molarity is a unit of concentration measuring the number of moles of a solute per litre of solution.
Chemists primarily need the concentration of solutions to be expressed in a way that accounts for the number of particles that react according to a particular chemical equation. Since percentage measurements are based on either mass or volume, they are generally not useful for chemical reactions. A concentration unit based on moles is preferable.
Given,
Volume of NaOH = 50 ml
Concentration of NaOH = 1M
Volume of HCl = 10ml
Concentration of NaOH × Volume of NaOH = Concentration of HCl × Volume of HCl
1 × 50 = c × 10
Concentration of HCl = 5 M.
Therefore, the molarity of the HCl solution is 5M and the correct option is option C.
