A 10.0-liter flask contains 1.013 grams of oxygen and .572 grams of carbon dioxide at 180C. What are the partial pressures of oxygen and carbon dioxide? What is the total pressure? What is the mole fraction of oxygen in the mixture?

Answers

P tot = 0.1065 atm

The mole fraction of oxygen in the mixture : 0.709

Further explanation

Given

10 L flask

1.013 g O₂

572 g CO₂

T = 18 °C = 291 K

Required

P O₂ and P CO₂

Solution

Dalton Law's of partila pressure

P tot = P₁ + P₂ + ..Pₙ

From ideal gas Law :

[tex]\tt P_{O_2}=\dfrac{\dfrac{1.013}{32}\times 0.082\times 291 }{10}\\\\P_{O_2}=0.0755~atm[/tex]

[tex]\tt P_{CO_2}=\dfrac{\dfrac{0.572}{44}\times 0.082\times 291}{10}\\\\P_{CO_2}=0.031~atm[/tex]

P tot = P O₂ + P CO₂

P tot = 0.0755 + 0.031

P tot = 0.1065 atm

The mole fraction of  O₂ :

[tex]\tt P_{O_2}=X_{O_2}\times P_{tot}\\\\X_{O_2}=\dfrac{P_{O_2}}{P_{tot}}\\\\X_{O_2}=\dfrac{0.0755~atm}{0.1065~atm}\\\\X_{O_2}=0.709[/tex]

The only way to see the far side of the moon is

Answers

The side of the Moon we do not see from Earth gets just as much sunlight on it as the side we do see. In truth, the only dark side of the Moon is the side that is pointed away from the Sun at any given time.The moon's mysterious far side is so much different than its near side, which we see in the night sky, and now scientists think they know why. ... In fact, observations have shown that only about 1% of the moon's far side is covered with maria, or craters caused by volcanic activity on the moon.

Answer:

Only one side of the spherical Moon is ever visible from Earth it wasn't until 1959 when the Soviet Spacecraft Luna 3 orbited the Moon and sent pictures home that human beings were able to see the "far side" of the Moon for the first time. A phenomenon called tidal locking is responsible for the consistent view

4. A cake recipe calls for 0.080 moles of baking soda (NAHCO3).What mass should the chef measure out?

5. The chemical formula for rust is Fe203. If the total mass of rust on a 1967 Chevy corvette is 190 kg, how many moles is that?

Answers

Answer:

1. 0.0033 moles of water.

2. 270g of water

3. 12.8g NaCl

4. 6.72g NaHCO3

5. 1190moles Fe2O3

Explanation:

To convert moles to grams or vice versa we require tu use molar mass of the substance as follows:

1. Molar mass water: 18g/mol

0.060g * (1mol / 18g) = 0.0033 moles of water

2. Molar mass water: 18g/mol

15 moles H₂O * (18g / 1mol) = 270g of water

3. We can assume all sea salt is NaCl -Molar mass: 58.44g/mol-

750g NaCl * (1mol / 58.44g) = 12.8g of NaCl

4. Molar mass NaHCO₃: 84g/mol:

0.080mol * (84g/mol) = 6.72g NaHCO3

5. Molar mass Fe2O3: 159.69g/mol:

190kg = 190000g * (1mol / 159.69g) = 1190moles Fe2O3

List four greenhouse gases in the atmosphere. For each gas, describe its prevalence in the atmosphere, its natural sources, its human-induced sources, and how its concentration in the atmosphere might be changing.

Answers

Answer: Carbon Dioxide, Methane, Nitrous Oxide and Fuorinated Gases

Explanation:Carbon dioxide (CO2): Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials, and also as a result of certain chemical reactions (e.g., manufacture of cement). Carbon dioxide is removed from the atmosphere (or "sequestered") when it is absorbed by plants as part of the biological carbon cycle.

Methane (CH4): Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from livestock and other agricultural practices and by the decay of organic waste in municipal solid waste landfills.

Nitrous oxide (N2O): Nitrous oxide is emitted during agricultural and industrial activities, combustion of fossil fuels and solid waste, as well as during treatment of wastewater.

Fluorinated gases: Hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride are synthetic, powerful greenhouse gases that are emitted from a variety of industrial processes. Fluorinated gases are sometimes used as substitutes for stratospheric ozone-depleting substances (e.g., chlorofluorocarbons, hydrochlorofluorocarbons, and halons). These gases are typically emitted in smaller quantities, but because they are potent greenhouse gases, they are sometimes referred to as High Global Warming Potential gases ("High GWP gases").

Answers

Answer: [tex]Pb(NO_3)_2(aq)+2NH_4Cl(aq)\rightarrow PbCl_2(s)+2NH_4NO_3(aq)[/tex] .

The insoluble product is lead (II) chloride.

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

A double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.

What property of water makes it a good choice to use to cool down hot
material quickly ?

Answers

Answer:

Because of its high heat capacity, water can minimize changes in temperature. For instance, the specific heat capacity of water is about five times greater than that of sand. The land cools faster than the sea once the sun goes down, and the slow-cooling water can release heat to nearby land during the night.

Answers

Doing this because I know I'm kickass at Chemistry.

One source would be human emissions. As humans, we use a lot of machines (like power plants) that produce large amounts of carbon dioxide into the atmosphere. The ocean also produces a lot of carbon dioxide via the evaporation cycle. Polluted waters eventually will go into the atmosphere. Volcanoes, even when not erupted, emit a lot of carbon dioxide as well. Dormant underground magma releases carbon dioxide through the Earth's pores, and even when a volcano erupts, it produces carbon dioxide as well.

What is balancing of a reaction?

Balancing of a reaction is done according to the "Law of conservation of mass" and balancing helps in solving stoichiometry questions correctly as if we will not balance the reaction then the quantitative results in a particular question doesn't come correctly.

Balancing of a reaction helps in mole concept as well and it is one of the laws of chemical reactions as well.

Some examples of balanced chemical reactions are-

2Mg(s) + O₂(g) ⟶ 2MgO(g)

Ca(OH)₂ + H₃PO₄ → Ca₃(PO₄)₂ + H₂O

Therefore, Among the following equations the one that represents the balanced equation for the reaction of iron and oxygen is a.

Speeding up a chemical reaction

Required

Factors used to speed up reactions

Solution

There are several factors that influence reaction kinetics :  

1. Concentration  

2. Surface area  

3. Temperature  

4. Catalyst  

5. Pressure  

6. Stirring  

Temperature is related to the kinetic energy of the particles. Heat is absorbed causes the particles of matter to move faster so that the reaction can take place faster

The enlarged surface area of the reactants causes more particles to react with other particles.
