Since you have a

mole ratio between glucose and water, you can determine how much water you would get by

⋅

1 mole glucose

180.0 g

⋅

6 moles of water

1 mole glucose

⋅

18.0 g

1 mole water

=

7.20

g

This represents your theoretical yield. If the percent yield is 100%, the actual yield will be equal to the theoretical yield. However, after you do the experiment you discover that only 6.50 g of water were produced.

Since less than what was calculated was actually produced, it means that the reaction's percent yield must be smaller than 100%. This is confirmed by

% yield

=

6.50 g

7.20 g

⋅

100

You can backtrack from here and find out how much glucose reacted

65.0 g of water

18.0 g

⋅

1 mole glucose

So not all the glucose reacted, which means that oxygen was not sufficient for the reaction - it acted as a limiting reagent.

Answer:

Lead may disrupt the functioning of mitochondria in the developing brain. Because the mitochondria are important for energy production within a neuron, a change in their function may damage the cell. Lead may also affect brain function by interfering with neurotransmitter release and synapse formation.

The theoretical yield can be calculated using the formula: Theoretical Yield (in grams) = (number of moles of limiting reactant) x (molar mass of product)

The theoretical yield of a reaction is the maximum amount of product that can be obtained from a given amount of reactants, assuming 100% efficiency. To calculate the theoretical yield, the balanced chemical equation for the reaction must be known. Then, the number of moles of reactant consumed by one mole of product can be determined from the stoichiometry of the reaction.

The limiting reactant is the reactant that is completely consumed before the other reactants, and it determines the maximum amount of product that can be produced. It is important to note that the theoretical yield is just a prediction and that the actual yield obtained in a reaction may be lower due to various factors such as incomplete reactions, loss of product, or impurities. The theoretical yield provides a benchmark for determining the efficiency of a reaction.

Aldehydes that contain at least one alpha hydrogen atom can undergo Aldol condensation and Cannizzaro reaction.

As per the question given,  

In Aldol condensation, two aldehyde or ketone molecules react in the presence of a base to form a beta-hydroxy carbonyl compound. The reaction involves the removal of a water molecule from the alpha-carbon and carbonyl group of two aldehydes or ketones. This reaction produces Aldol, which can undergo dehydration to form an alpha-beta-unsaturated carbonyl compound.

On the other hand, in the Cannizzaro reaction, an aldehyde molecule undergoes self-oxidation and reduction in the presence of a strong base to give an alcohol and a carboxylic acid. The reaction involves the loss of a hydrogen atom from the aldehyde, which gets reduced to an alcohol, and the reduction of the other aldehyde molecule to a carboxylic acid.

Therefore, aldehydes containing at least one alpha hydrogen atom can undergo Aldol condensation and Cannizzaro reaction.

Explain the advantages of subdividing science into many different areas. Advantages-It allows scientists to delve into a specific topic easier, so that they can go deeper.

hope it helps

Answer:

Science is a vast subject. Scientists have classified it into different areas/branches so that they do not get their concepts mixed or overlapped. We can think of all the sub-branches as different topics studied under one main subject, science. We just divide the main subject so that we can study each of the topic clearly and individually. Science is such a vast subject that most of its sub branches are not even related to each other or interlinked, like computer science and biology. If we did not have subdivisions in science, can you imagine a person studying biology, computer science, chemistry, physics, phycology etc all at the same time, simultaneously? Of course not! That's why, in order to get a clear understanding of each topic, we divide science into different areas.

Answer:

Its Neon

Explanation:

Why ? Because Neon is the fastest it can go to 435 m/s and thats one of the fastest element there.

Helium would have the fastest rate of diffusion. Therefore, option (C) is correct.

Graham’s law states that the rate of diffusion of a gas is inversely proportional to the square root of the molecular weight of that gas.

According to Graham’s Law, molecules of gas with lower molecular mass at constant pressure and temperature will diffuse faster than the higher molecular mass molecules. This formula is commonly utilized to compare the rates of diffusion of two different gases at the same pressures and temperatures.

\(\frac{Rate_1}{Rate_2} =\sqrt{\frac{M_2}{M_1} }\)

Where M₁ is the molar mass of gas 1 while M₂ is the molar mass of gas 2.

The atomic mass of He, Ne, Ar, and Ke is 4, 20, 40, and 83 g/mol. The helium gas has the lowest atomic mass so it has the highest rate of diffusion while Krypton has the lowest rate of diffusion.

The pH of acidic wastewater is 3.2, indicating a high concentration of hydrogen ions and a low concentration of hydroxide ions. This suggests that the wastewater is highly acidic.

Using acidic wastewater for irrigation can have several risks. Firstly, it can negatively affect the pH balance of the soil, making it less suitable for crop growth. Additionally, the high concentration of hydrogen ions in acidic wastewater can lead to toxicity in plants, potentially damaging their roots and inhibiting their overall growth. Moreover, if the runoff from the wastewater fills a drinking basin for livestock, it can be harmful to their health, as animals are sensitive to the quality of the water they consume.

To reduce pests on the farmer's site without the use of pesticides, an alternative sustainable farming practice can be employed. Integrated Pest Management (IPM) techniques can be implemented, which focus on prevention, monitoring, and control of pests through biological, cultural, and physical methods. This includes practices such as crop rotation, habitat manipulation, companion planting, and the use of beneficial insects. By implementing IPM, the farmer can reduce pests effectively while minimizing the risks associated with the use of pesticides and harmful wastewater.

Explanation:

Small molecules make up water. There are three of them: two hydrogen atoms and one oxygen atom. Hydrogen bonding is a force that holds water molecules together. It is the cause of water's extraordinary abilities.

Our bodies require water for the following reasons:

1. It soothes joints:  In the spine's disks and in joints, cartilage contains about 80% water. Over time, dehydration can reduce the joints' ability to absorb damage, which can result in joint pain.

2.It produces mucous and saliva: Saliva helps in digestion and keeps the eyes, nose, and lips moist. Wear and tear are prevented in this way. Furthermore, drinking water maintains the mouth healthy. When substituted for sweetened beverages, it can also stop tooth decay.

3. It delivers oxygen throughout the body: Blood transports oxygen to various parts of the body and contains more than 90% water.

4. It protects delicate areas of the spinal cord and brain with padding: Brain anatomy and function can be impacted by dehydration. Additionally, it contributes to the synthesis of neurotransmitters and hormones. Long-term dehydration can cause issues with reasoning and thinking.

5. It controls the body's temperature: Perspiration is the result of the middle-layers of the skin's stored water being released when the body becomes hot. Evaporation causes the body to cool. in a sport. Some scientists claim that: Source of reality When the body doesn't have enough water, it can't handle heat stress as well, and it stores more heat. Lots of water consumption may help to reduce physical stress if heat stress occurs when exercising. Yet additional research is needed to fully understand these effects.

6. Water is necessary for the digestive system: The bowel need water to operate properly. Dehydration can lead to constipation, excessive stomach acid, and digestive problems. The likelihood of stomach ulcers and heartburn has increased as a result.

7. It keeps blood pressure stable: Lack of water can cause blood to become thicker. Enough water may reduce the likelihood of vasopressin release, which reduces the risk of high blood pressure, by keeping our cells and organs hydrated.

8. Water prevents kidney damage: The kidneys are in charge of body fluid. Water deficiency may result in kidney stones and other problems. Water is required by the bowel for proper operation. Dehydration can cause digestive problems such as constipation, excessive stomach acid, and more. As a result, it is now more probable to have heartburn and stomach ulcers.

The approximate amount of water used in the reaction is 1000 g. Student B is correct.

From the equation of the reaction, the mole ratio of the H2 produced and the H2O separated is 1:1.

mole of H2 produced = mass/molar mass

                                        = 112/2

                                           = 56 moles

This means that 56 moles of H2O was also separated.

Mass of 56 moles of H2O = 56 x 18

                                           = 1,008 g

Also from the equation of the reaction, the mole ratio of O2 produced to water separated is 1:2.

Mole of O2 produced = 888/32

                                       = 27.75 moles

Equivalent mole of H2O = 27.75 x 2

                                        = 55.5 moles

Mass of 55.5 moles of H2O = 55.5 x 18

                                               = 999 g

Thus, the approximate amount of water used in the reaction must have been 1000 g. Student B is correct.

(9) The following statement about Polymer Crystallinity is incorrect : c) Crystallinity is reduced for polymers that are chemically simple and that have regular and symmetrical chain structures ; 10 ) b)  The density of crystalline polymer > Density of amorphous polymer.

9) Polymers have two types of molecular structures: amorphous and crystalline. Amorphous polymers lack an ordered molecular structure and, therefore, a distinct melting point, whereas crystalline polymers have ordered molecular structures and can melt at a specific temperature. In addition to being entirely amorphous, polymers may also exhibit varying degrees of crystallinity.

A polymer with greater crystallinity, for example, has more organized regions in which the chains of molecules are tightly packed together. The degree of crystallinity of a semicrystalline polymer is determined by its density. In the polymer, the crystalline regions are more dense than the amorphous regions, resulting in a correlation between crystallinity and density.

(10) The density of crystalline polymer > Density of amorphous polymer. This is because in the polymer, the crystalline regions are more dense than the amorphous regions. Because the crystalline polymer has a more ordered molecular structure and a greater degree of crystallinity than the amorphous polymer, the density of the crystalline polymer is higher.
