What are the products of the following reactions? (A trace amount of acid is present in each case.)
A. cyclopentanone + ethylamine
B. cyclopentanone + diethylamine
C. acetophenone + hexylamine
D. acetophenone + cyclohexylamine
Answers
Carbonyl compounds are organic compounds that contain a carbonyl group (C=O). These include the ketones and aldehydes. Ketones are those that have two alkyl groups attached to the carbonyl carbon while aldehydes are those that contain an alkyl group and a hydrogen atom. These compounds can undergo addition reactions with primary and secondary amines which results in the formation of imines and enamines.
The products of the given reactions are shown in the completed equations given attachment.
Reactions A, C and D results in the formation of an imine since ethylamine, hexylamine and cyclohexylamine are all primary amines. Reaction B, on the other hand, produces an enamine since diethylamine is a secondary amine.

how many moles of water is 5.02 x 10 18 molecules of water
Answers
Answer:
8.334×10^-6 moles
Explanation:
a mole is 6.023×10^23
5.02×10^18 ÷ 6.023×10^23=8.33×10^-6
so there are 8.33×10^-6 moles of water in 5.02x10^18 molecules of water
The number of moles of water in which 5.02 × 10¹⁸ molecules of water is present is 8.33 × 10⁻⁶.
What is moles?
Moles is a unit which is used to tells about the quantity of any substance, in one moles of any substance 6.023 × 10²³ number of atoms of that substances are present.
In 1 mole of water = 6.023 × 10²³ number of molecules of water is present
So, number of 5.02 × 10¹⁸ molecules of water present in how many moles will be calculated as:
Required moles = 5.02 × 10¹⁸ / 6.023 × 10²³ = 8.33 × 10⁻⁶
Hence, required moles is 8.33 × 10⁻⁶.

Calculate the volume of 150kg of chlorine gas at room temperature and pressure. The volume of one mole of gas at room temperature and pressure is 24.0dm^3. Relative formula mass (Mr): Cl2=71
Answers
Answer:
Given mass 150 kg= 150000 gram
molar mass 71 gram
number of moles = given mass/molar mass
= 2112.76 moles
1 mole = 24 Dm³
2112.76 mole =24×2112.76= 50706.24 Dm³
The volume of the mole of gas at room temperature and pressure is 50,704.08dm³
We need to first calculate the number of moles of Chlorine gas (Cl₂)
Number of moles = Mass/Molar mass
Given the following parameters
The molar mass of Cl₂ = 71g/mol
Mass of chlorine gas = 150kg = 150,000g
Get the number of moles
[tex]n=\frac{150,000}{71}\\n=2,112.67moles\\[/tex]
Given that volume of 1 mole at STP = 24.0dm³
2112.67 moles = x
Get the volume of the chlorine gas at STP.
Volume of Cl₂ at STP = 24 × 2112.67
Volume of Cl₂ at STP = 50,704.08dm³
Hence the volume of the mole of gas at room temperature and pressure is 50,704.08dm³

These data are blank with the law of conservation of mass because the mass of reactants blank the mass of products. the mass of products.
Answers
Answer: The data are consistent with the law of conservation of mass because the mass of reactants equals the mass of products
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
Given: mass of sodium = 12.8 g
mass of chlorine = 19.6 g
mass of reactants = mass of sodium + mass of chlorine = 12.8 g + 19.6 g = 32.4 g
Mass of product = Mass of sodium chloride = 32.4 g
As mass of reactant = mass of products , Thus results are in accordance with the law of conservation of mass.
Identify one factor represented in the diagram that is used to classify the ten types of clouds
Answers
Stratus clouds are uniform grayish clouds that often cover the sky. Usually no precipitation falls from stratus clouds, but they may drizzle. When a thick fog “lifts,” the resulting clouds are low stratus. Nimbostratus clouds form a dark gray, “wet” looking cloudy layer associated with continuously falling rain or snow. They often produce light to moderate precipitation.
Middle clouds
Clouds with the prefix “alto” are middle-level clouds that have bases at 6,500 to 23,000 feet up. Altocumulus clouds are made of water droplets and appear as gray, puffy masses, sometimes rolled out in parallel waves or bands. These clouds on a warm, humid summer morning often mean thunderstorms by late afternoon. Altostratus clouds, gray or blue-gray, are made up of ice crystals and water droplets. They usually cover the sky. In thinner areas of them, the sun may be dimly visible as a round disk. Altostratus clouds often form ahead of storms that produce continuous precipitation.
High clouds
Cirrus clouds are thin, wispy clouds blown by high winds into long streamers. They are considered “high clouds,” forming at more than 20,000 feet. They usually move across the sky from west to east and generally mean fair to pleasant weather. Cirrostratus, thin, sheetlike clouds that often cover the sky, are so thin the sun and moon can be seen through them. Cirrocumulus clouds appear as small, rounded white puffs. Small ripples in the cirrocumulus sometimes resemble the scales of a fish, creating what is sometimes called a “mackerel sky.”
Vertical clouds
Cumulus clouds are puffy and can look like floating cotton. The base of each is often flat and may be only 330 feet above ground. The top has rounded towers. When the top resembles a cauliflower head, it is called “cumulus congestus.” These grow upward and if they continue to grow vertically can develop into a giant cumulonimbus, a thunderstorm cloud, with dark bases no more than 1,000 feet above ground and extending to more than 39,000 feet. Tremendous energy is released by condensation of water vapor in a cumulonimbus. Lightning, thunder and violent tornadoes are associated with them.

1. What pressure would be exerted by 46.0grams of hydrogen gas placed into a 3.00 L container at
25°C?
Answers
Answer:
187.34 atm
Explanation:
From the question,
PV = nRT.................. Equation 1
Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.
make P the subject of the equation
P = nRT/V.............. Equation 2
n = mass(m)/molar mass(m')
n = m/m'............... Equation 3
Substitute equation 3 into equation 2
P = (m/m')RT/V............ Equation 4
Given: m = 46 g, T = 25°C = (25+273) = 298 K, V = 3.00 L
Constant: m' = 2 g/mol, R = 0.082 atmL/K.mol
Substitute these values into equation 4
P = (46/2)(0.082×298)/3
P = (23×0.082×298)/3
P = 187.34 atm
El mercurio ha sido utilizado como elemento para medir la temperatura porque Es una mezcla. Al aumentar la temperatura se dilata con facilidad. Es un buen conductor del calor. Es un buen conductor de la electricidad.
Answers
Answer:
La respuesta correcta es: Al aumentar la temperatura se dilata con facilidad
Explanation:
El mercurio (Hg) es un elemento metálico que a temperatura ambiente es un líquido. Tiene la propiedad de dilatarse con facilidad al aumentar la temperatura, propiedad que ha sido utilizada en los termómetros de mercurio. En estos termómetros, el mercurio está dentro de un tubo de vidrio graduado con un bulbo para transmitir el calor. Al estar en contacto con un cuerpo más caliente (a mayor temperatura), el mercurio del interior del termómetro se dilata (expande su volumen) y asciende por el tubo indicando la temperatura correspondiente, graduada en el vidrio.
If 27.3g of C8H18 is combusted, according to the equation below, what mass of water is produced?
2C8H18 + 25O2 --> 16CO2 + 18 H2O,
molar masses: C8H18 = 114.3 g/mol O2 = 32.0 g/mol CO2 = 44.0 g/mol H2O = 18.0 g/mol
Answers
Answer:
38.7 g
Explanation:
2C₈H₁₈ + 25O₂ → 16CO₂ + 18 H₂OFirst we convert 27.3 grams of C₈H₁₈ into moles, using the given molar mass:
27.3 g C₈H₁₈ ÷ 114.3 g/mol = 0.239 mol C₈H₁₈Then we convert 0.239 moles of C₈H₁₈ into moles of H₂O, using the stoichiometric coefficients of the reaction:
0.239 mol C₈H₁₈ * [tex]\frac{18molH_2O}{2molC_8H_{18}}[/tex] = 2.151 mol H₂OFinally we convert 2.151 moles of H₂O into grams, using water's molar mass:
2.151 mol H₂O * 18.0 g/mol = 38.7 gWhich phrase best describes an individual organ?
