You are working on an experiment that requires Iodine (I) to have a full outer shell. What element could you combine it with to get a full outer shell? A. Lithium (Li) B. Sulfur (S) C. Neon (Ne) D. Oxygen (O)

The percent yield of carbon dioxide will be 49.0 %.

First, let's look at the equation of the reaction:

\(2C_8H_1_8 + 25O_2 -- > 16CO_2 + 18H_2O\)

The mole ratio of octane to oxygen is 2:25.

Mole of 3.43 g octane = 3.43/114.23 = 0.03 mol

Mole of 19.1 g oxygen = 19.1/32 = 0.60 mol

Thus, octane is limiting.

Mole ratio of octane to carbon dioxide = 2:16.

Equivalent mole of carbon dioxide = 0.03 x 8 = 0.24 mol

Mass of 0.24 mol carbon dioxide = 0.24 x 44.01 = 10.5624 grams

Percent yield of carbon dioxide = 5.18/10.5624 = 49.0 %

Answer:

The Answer will be provided below, please pay attention in class next time so that you don't have to be in a hurry like you are in now.

Explanation: The correct option is:

Both fossil fuels and wind energy can be used to produce electricity. However, burning fossil fuels does pollute the atmosphere, while using Earth's wind does not. Both fossil fuels and wind energy contribute to climate change, but the use of fossil fuels is much more damaging to the environment than the use of wind power.

Fossil fuels are non-renewable sources of energy that are formed over millions of years by the decomposition of organic matter. They release harmful greenhouse gases when burned, contributing to climate change. In contrast, wind energy is a renewable source of energy that uses turbines to harvest the power of wind. Wind energy does not produce any emissions, making it an environmentally friendly alternative to fossil fuels. While wind turbines can have some impacts on wildlife and habitats, the impact is much less severe than the effects of fossil fuel extraction and burning.

Added Part: Fossil fuels are non-renewable sources of energy that are derived from the remains of plants and animals that died millions of years ago. These sources include coal, oil, and natural gas. Wind energy, on the other hand, is a renewable source of energy that is generated by the kinetic energy of wind.

Here are some comparisons between fossil fuels and wind energy:

Environmental Impact: Fossil fuels have a significant negative impact on the environment. Burning fossil fuels produces greenhouse gases that contribute to climate change. The extraction of fossil fuels also has negative impacts on the air, water, and soil. Wind energy, however, has a very small environmental footprint. Wind turbines do not produce any emissions and do not require any water to generate electricity.

Energy Availability: Fossil fuels are abundant and have been the primary source of energy for decades. On the other hand, wind energy is a relatively new source of energy and the technology is still developing. However, the availability of wind energy is significant, as wind is a renewable source that is constantly available.

Sustainability: Fossil fuels are non-renewable, which means they will eventually run out. As the demand for energy continues to increase, the availability of fossil fuels will decrease. Wind energy is a renewable source of energy that will never run out.

Here are some pros and cons of both fossil fuels and wind energy:

Fossil Fuels:

Pros:

Reliable source of energy

High energy density

Large global infrastructure

Cons:

Non-renewable source of energy

Significant environmental impact

Price instability

Wind Energy:

Pros:

Renewable source of energy

Small environmental footprint

Low operating costs

Cons:

High initial costs for building wind turbines

Wind is an inconsistent source of energy

Can create noise pollution for surrounding communities

Answer:

Mass =   253.4 g

Explanation:

Given data:

Mass of oxygen required = ?

Mass of hydrogen available = 32.0 g

Solution:

Chemical equation:

2H₂ + O₂     →       2H₂O

Number of moles of hydrogen:

Number of moles = mass/molar mass

Number of moles = 32.0 g/ 2.02 g/mol

Number of moles = 15.84 mol

Now we will compare the moles of hydrogen and oxygen:

                  H₂         :           O₂

                   2          :           1

              15.84        :         1/2×15.8 = 7.92 mol

Mass of oxygen required:

Mass = number of moles × molar mass

Mass = 7.92 mol × 32.00 g/mol

Mass =   253.4 g

Sickle cell anemia is a genetic blood disorder that affects shape and function of red blood cells.

Sickle cell anemia is a genetic blood disorder that affects the shape and function of red blood cells. Hemostasis refers to process of maintaining balance between clotting and bleeding and sickle cell anemia can disrupt this balance in several ways.

One of the main effects of sickle cell anemia on hemostasis is that it can cause Vaso-occlusion, which is blockage of small blood vessels by sickle cells. This can cause tissue damage, inflammation and pain, which in turn can trigger an overactive clotting response.

Sickle cell anemia is caused by mutations in HBB gene, which provides instructions for making protein called hemoglobin.

Sickle cell anemia is most commonly found in people of African descent, although it can also occur in people of Hispanic, Middle Eastern, and Mediterranean ancestry.

Diagnosis of sickle cell anemia involves blood test to look for the presence of sickle hemoglobin.

The perfect gas equation of state is a fundamental law in thermodynamics that describes the relationship between the pressure, volume, and temperature of a gas. It is given by the equation:

PV = nRT

where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, R is the universal gas constant, and T is the temperature of the gas in kelvin.

The perfect gas equation of state can be derived by combining three laws:

Boyle's law: This law states that the pressure of a gas is inversely proportional to its volume at a constant temperature. Mathematically, it can be expressed as:

P1V1 = P2V2

where P1 and V1 are the initial pressure and volume of the gas, and P2 and V2 are the final pressure and volume.

Charles's law: This law states that the volume of a gas is directly proportional to its absolute temperature at constant pressure. Mathematically, it can be expressed as:

V1/T1 = V2/T2

where V1 and T1 are the initial volume and temperature of the gas, and V2 and T2 are the final volume and temperature.

Avogadro's principle: This principle states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. Mathematically, it can be expressed as:

V1/n1 = V2/n2

By combining these three laws, we can derive the perfect gas equation of state. First, we can rearrange Boyle's law to express pressure in terms of volume:

P = P1V1/V

Next, we can substitute this expression for P into Charles's law:

V1/T1 = V2/T2

V1/T1 = V1(P1V1)/(T2V)

T2 = (P1V1T1)/(V)

Similarly, we can rearrange Avogadro's principle to express volume in terms of the number of moles:

V = nRT/P

Substituting this expression for V into the equation we obtained from Charles's law, we get:

T2 = (P1V1T1)/(n1R)

Finally, we can rearrange this equation to isolate the pressure term, which gives us the perfect gas equation of state:

PV = nRT

Thus, by combining Boyle's law, Charles's law, and Avogadro's principle, we can derive the perfect gas equation of state, which is a fundamental law in thermodynamics that describes the behavior of ideal gases.
