Answer:

312g O₂ son necesarios, se producen 264g CO₂ y 135g H₂O

Explanation:

La combustión de butano para producir CO₂ y H₂O ocurre así:

C₄H₁₀ + 13/2O₂ → 4CO₂ + 5H₂O

Donde 1 mol de butano reacciona con 13 moles de oxígeno para producir 4 moles de dióxido de carbono y 5 moles de agua.

Para resolver este problema debemos convertir la masa de butano a moles y, usando la reacción balanceada, obtener cuánto se necesita de oxígeno y cuánto se produciría de dióxido de carbono y agua:

Moles butano -Masa molar: 58.12g/mol-:

87.0g * (1mol / 58.12g) = 1.50 moles

Moles y masa de oxígeno necesarias para la reacción -Masa molar: 32g/mol-:

1.50 moles C₄H₁₀ * (13/2 moles O₂ / 1 mol C₄H₁₀) = 9.75 moles * (32g/mol) =

312g O₂ son necesarios

Moles y masa de dióxido de carbono producidas -Masa molar: 44.01g/mol-:

1.50 moles C₄H₁₀ * (4 moles CO₂ / 1 mol C₄H₁₀) = 6 moles * (44.01g/mol) =

264g CO₂ se producen

Moles y masa de agua producidas -Masa molar: 18.015g/mol-:

1.50 moles C₄H₁₀ * (5 moles H₂O / 1 mol C₄H₁₀) = 7.5 moles * (18.015g/mol) =

135g H₂O se producen

Explanation:

There are three valence electrons in a boron atom.

In boron trifluoride, the central boron atom did not achieve an octet with eight valence electrons. Rather, that boron atom would be electron deficient with only six valence electrons.

Each of the three fluoride atoms would have shared one valence electron with that boron atom, with a total of three boron-fluorine single bonds. On the other hand, all three of the valence electrons of that boron atom would be involved in bonding. Hence, there would be no extra valence electrons to act as lone pairs on that boron atom.

Hence, the central boron atom would have three electron domains (one for each boron-fluorine bond) with none of the electron domains coming from lone pairs. By the VSEPR theory, the geometry of the molecule would be trigonal planar. All four atoms in this molecule would be in the same plane.

There are five valence electrons in a nitrogen atom.

In ammonia, the central nitrogen atom is indeed able to achieve an octet (with eight valence electrons in total.) Three of the five valence electrons of nitrogen would form a total of three hydrogen-nitrogen bonds. The other two valence electrons would form a lone pair.

Hence the central nitrogen atom would have four electron domains (one for each of the three hydrogen-nitrogen bond, and one for the lone pair.) Hence, by the VSEPR theory, the geometry of this molecule would be trigonal pyramidal.

Answer:

Neutral atoms of each element contain an equal number of protons and electrons. The number of protons determines an element's atomic number and is used to distinguish one element from another. ... Together, the number of protons and the number of neutrons determine an element's mass number.

Answer:

50 moles of many mango seeds = 2.107.10²⁴ mango

Further explanation

A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12

While the number of moles can also be obtained by dividing the mass (in grams) with the molar mass of element or molecule

With  Avogadro's number

N = number of gas particles

No = Avogadro number (6.02.10²³)

n = number of moles

n= N/No

3.50 moles of many mango seeds are comparable to

N mango seeds= 3.5 x 6.02.10²³

N mango seeds=2.107 x 10²⁴..

Answer:

4.5 moles

Explanation:

One mole is equal to 6.022 x 10^23 atoms

2.71 x 10^24 atoms * 1 mol/ 6.022 x 10^23 atoms = 4.5 moles

Answer:

6.27 X 10^26 atoms

Explanation:

Write down the formula:

number of moles = mass/Ar    (Ar is atomic mass)

Ar of carbon = 12

mass = 12.5kg or 12500g

Substitue these values into the formula:

number of moles = 12,500g / 12 = 3125/3 or 1041.6

Convert this to atoms:

1 mole = 6.022 X 10^23 atoms

So, 1041.6 moles = 6.27 X 10^26 atoms

Answer:The hydrogen bond is responsible for many of the anomalous physical and chemical properties of compounds of N, O, and F. In particular, intermolecular hydrogen bonding is responsible for the high boiling point of water (100 °C) compared to the other group 16 hydrides that have much weakerhydrogen bonds

Hydrogen bonding is primarily responsible for the high ______ of water.

Answer:

Biopolymers are natural polymers produced by the cells of living organisms. Biopolymers consist of monomeric units that are covalently bonded to form larger molecules. There are three main classes of biopolymers, classified according to the monomers used and the structure of the biopolymer formed: polynucleotides, polypeptides, and polysaccharides.

Answer:

1. 1 mole of NaCl.

2. 1 mole of H₂O.

Explanation:

The balanced equation for the reaction is given below:

HCl + NaOH —> NaCl + H₂O

From the balanced equation above,

1 mole of HCl reacted with 1 mole of NaOH to produce 1 mole of NaCl and 1 mole of H₂O.

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above, we can see that 1 mole of HCl reacted completely with 1 mole of NaOH. Therefore, HCl is the limiting reactant and NaOH is the excess reactant since we have 3.6 moles of NaOH.

1. Determination of the amount of NaCl produced from the reaction.

NOTE: The limiting reactant is used to determine the maximum amount produced since all of it is consumed in the reaction.

The limiting reactant is HCl and the amount of NaCl produced can be obtained as follow:

From the balanced equation above, we can see that 1 mole of HCl reacted to 1 mole of NaCl.

Thus, 1 mole of NaCl was produced.

2. Determination of the amount of H₂O produced from the reaction.

From the balanced equation above, it is evident that 1 mole of HCl reacted to produce 1 mole of H₂O.

Thus, 1 mole of H₂O was produced.

Explanation:

Answer:less than

Explanation:

If we had 79.3 grams of Xe, we would expect a volume that is less than obtained with neon. So, the correct option is (C).

Density is defined as the mass per unit volume of a substance. The most commonly used symbol for density is ρ, although the Latin letter d can also be used. Density is defined as mass divided by volume:

[tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]

where ρ is density,

m is mass, and

V is volume.

The mass contained per unit volume of an object is known as density. where the SI unit of density is kilogram per cubic meter [tex](kg/m^3).[/tex] Density is inversely proportional to volume, so the density of Xenon is [tex]5.894 kg/m^3[/tex] while the density of neon is 0.89994 kg/m³. So, if density is more than volume will be less and vice versa. In this case, density of Xenon is more as compare to neon so, the volume of neon will be more.

Thus, if we had 79.3 grams of Xe, we would expect a volume that is less than obtained with neon. So, the correct option is (C).
