5. Para la siguiente reacción: KClO3 (s) KCl(s) + O2

Si se descomponen 500 gramos de una muestra impura de clorato de potasio y se recogen 100 litros de O2 medidos bajo condiciones normales de presión y temperatura. Determine la pureza de la muestra.

Answers

Answer:

72.95%

Explanation:

Para resolver esta pregunta, debemos hallar las moles tóricas que se producirían en la reacción asumiendo que los 500g son únicamente de clorato de potasio haciendo uso de la reacción balanceada:

2KClO₃(s) → 2KCl(s) + 3O₂(g)

Donde dos moles de clorato de potasio producen tres moles de oxígeno.

Después de hallar las moles teóricas de oxígeno debemos hallar las moles producidas usando PV = nRT. La pureza SERÁ:

Moles producidas / moles Teóricas * 100

Moles clorato -Masa molar: 122.55g/mol-:

500g KClO₃ * (1mol / 122.55g) = 4.08 moles KClO₃

Moles O₂ teóricas:

4.08 moles KClO₃ * (3 moles O₂ / 2 moles KClO₃) = 6.12 moles

Moles producidas:

PV / RT = n

Donde P = 1atm a STP

V es volumen = 100L

R es constante de los gases = 0.082atmL/molK

T =273.15K a STP

Reemplazando:

1atm*100L / 0.082atmL/molK*273.15K = 4.46 moles

La pureza de la muestra es:

4.46 moles / 6.12 moles * 100 = 72.95%

What would happen to Earth's temperature if the energy absorbed from the sun (solar radiation) was less than the emitted (thermal) energy leaving the Earth?

Answers

Answer:

The Earth would become cooler until it probably attains a new equilibrium between absorbed solar energy and emitted solar energy.

Explanation:

The earth's energy balance refers to the balance between the energy absorbed from the sun (solar radiation) and the emitted (thermal) energy leaving the Earth. This balance ensures that the earth's surface temperature remains fairly constant.

When energy from the sun reaches the earth, it is absorbed and used by various features of the earth which uses it for their energy needs. Eventually, any excess radiant energy is sent back or emitted from the earth back into space such that the balance between absorbed and emitted energy is maintained.

However, if there is an imbalance whereby more energy is emitted than is absorbed, this would result in the earth losing more heat than it receives. This would result in the earth becoming more significantly colder until it probably attains a new equilibrium between absorbed solar energy and emitted solar energy.

Which of these statements describes a physical property of hydrogen? Group of answer choices it is found in acids. it is less dense than oxygen gas. it reacts with oxygen to form water. it is highly flammable.

Answers

Answer:

it is less dense than oxygen gas.

Explanation:

Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.

Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.

In Chemistry, the properties of a chemical element that can be observed and measured without changing its chemical nature is known as a physical property. It includes density, color, freezing point, opacity, smell, melting point, viscosity, etc.

Hence, the statement which describes a physical property of hydrogen is that it is less dense (density) than oxygen gas.

Which statement below accurately describes the atoms of a specific element?An antimony, Sb, atom contains 122 protons inside the nucleus and 51 neutrons outside the nucleus.A manganese, Mn, atom contains 55 electrons outside the nucleus and 25 neutrons inside the nucleus.A chlorine, Cl, atom contains 35 electrons and 27 protons inside the nucleus.An arsenic, As, atom contains 33 protons inside the nucleus and 33 electrons outside the nucleus.

Answers

Answer: An arsenic, As, atom contains 33 protons inside the nucleus and 33 electrons outside the nucleus.

Explanation:

The protons are positively charged, electrons are negatively charged and neutrons has no charge (neutral).  The protons and neutrons are present inside the nucleus and the electrons are located outside the nucleus.

Antimony (Sb) has an atomic number of 51 and thus contains 51 electrons and 51 protons. It has a mass number of 121 and thus conatins 70 neutrons.

Manganese (Mn) has an atomic number of 25 and thus contains 25 electrons and 25 protons.

Chlorine (Cl) has an atomic number of 17 and thus contains 17 electrons and 17 protons.

Arsenic (As) has an atomic number of 33 and thus contains 33 electrons and 33 protons.

What pressure would be required to take 100.0 ml of a gas at 103.0 kPa and squish it down to 2.00 ml

Answers

Answer:

5150 kPa

Explanation:

Given that,

Initial volume, V₁ = 100 mL

Initial pressure, P₁ = 103 kPa

Final volume, V₂ = 2 mL

We need to find the new pressure of the gas. The relation between the pressure and the volume of gas is given by :

[tex]P_1V_1=P_2V_2\\\\P_2=\dfrac{P_1V_1}{V_2}\\\\P_2=\dfrac{103\times 100}{2}\\\\P_2=5150\ kPa[/tex]

So, the new pressure is 5150 kPa.

Work out the empirical formula of a compound that contains 35% of nitrogen , 5% of hydrogen and 60% of oxygen.

Answers

Answer:

[tex]H_5N_5O_6[/tex]

Explanation:

Hello there!

In this case, for the determination of empirical formulas, it is firstly necessary to assume the given percentages of the constituent atoms as the masses so we can compute their moles in the formula:

[tex]n_N=\frac{35gN}{14.01g/mol} =2.5molN\\\\n_H=\frac{5g}{1.01 g/mol}=5molH\\\\n_O=\frac{60g}{16 g/mol} =3molO[/tex]

Thus, we need to divide the resulting moles, by the fewest ones (those of nitrogen) in order to determine the coefficients in the formula:

[tex]N:\frac{2.5}{2.5}=1\\\\H:\frac{5}{2.5}=2\\\\O:\frac{3}{2.5} =1.2[/tex]

However, we need to turn all these numbers, whole numbers, so we multiply by 5 to get:

[tex]H_5N_5O_6[/tex]

in what two ways do minerals form​

Answers

Answer:

Minerals can form in three primary ways being precipitation, crystallization from a magma and solid- state transformation by chemical reactions (metamorphism). Mineral Precipitation is when a mineral is formed by crystallization from a solution. Examples include quartz, halite (table salt), calcite, and gypsum.

Answer:

When magma cools slowly, deep below the surface, it has time to form large crystals in regular patterns. The second way that minerals form is through solutions. (A solution is when one substance is dissolved uniformly in a liquid.) When elements and compounds leave the solution, they can crystalize.

This unit discusses in detail the role of catalysts to lower the activation energy of reactions. The term catalyst appears in nonscientific discussions to refer to something that provokes or speeds significant change or action. Consider this example from the 2006 Associated Press article "Chernobyl cover-up a catalyst for glasnost":

"For the Soviet Union, Chernobyl was a catalyst that forced the government into an unprecedented show of openness that paved the way for reforms leading to the Soviet collapse"

Discuss how this scientific term has made its way into common usage. Does the term catalyst carry the same meaning in regular usage? How is it used differently in a scientific context compared to a nonscientific contexte​

Answers

Answer:

It can be brought into regular conversation easily I feel it means to "provoke" or "speeds significant change or action" I can see someone saying that in a conversation, "chlorine acts as a catalyst promoting the breakdown of ozone".

I would say it would take the same meaning depending on how you say it and when and what the context of what you're saying it in. 

For scientists, it means to change quickly. For someone who says it in a conversation may be saying to stop provoking someone.

Explanation:

An electron has an acceleration of 2.33*10² [tex]\frac{m}{sec^{2} }[/tex]

To be able to express in units [tex]\frac{m}{min^{2} }[/tex], you must carry out the conversion taking into account that 1 [tex]\frac{m}{sec^{2} }[/tex]= 3600 [tex]\frac{m}{min^{2} }[/tex].

[tex]\frac{m}{min^{2} }=\frac{2.33*10^{2} \frac{m}{sec^{2} }*3600\frac{m}{min^{2} }}{1\frac{m}{sec^{2} }}[/tex]

[tex]\frac{m}{min^{2} }=838800[/tex]

click on the picture of the flowers until their colors correspond to the punnett square above. HELP PLZ!

Answers

Answer:

You will need to have a red flower in the top left, a pink flower in the top right and bottom left, and a white flower in the bottom right.

Explanation:

This flower appears to express color through codominance, which means that both genes express themselves. "R" is the dominant gene for red, and "r" is the recessive gene for white. When a flower has RR genotype, the phenotype will be a red flower. When a flower has an Rr genotype, the red and white genes will both be expressed and the phenotype will be pink. When a flower has an rr genotype, it lacks the red gene and will therefore be only white.
