Answer:

Unbalanced= Fe + H2SO4 Fe2(SO4)3 + H2

Balanced with same coefficients in the same order= 2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2

Explanation:

Balancing a chemical equation means having the same number of atoms of an element on the reactant side as on the product side in accordance to the law of conservation of mass. To do this, coefficients (number behind the element) are used.

In this question,the below balanced equation was given

2CO2 + 3H20 ---> C2H6O + 3O2

Four other unbalanced equations were also given to be balanced and see which will have the same coefficients in the same order as the template equation. Let's start balancing each equation.

1. FeCl3 + NH4OH ---> Fe(OH)3 + NH4Cl (unbalanced)

Atoms of nitrogen, hydrogen, oxygen and Chlorine are unequal in both sides. Hence, we have

FeCl3 + 3NH4OH ---> Fe(OH)3 + 3NH4Cl (balanced)

2. CH4 + O2 ---> CO2 + H2O (unbalanced)

Atoms of hydrogen and oxygen are unequal in both sides. We have;

CH4 + 2O2 ---> CO2 + 2H2O (balanced)

3. Fe + H2SO4 ---> Fe2(SO4)3 + H2 (unbalanced)

Atoms of iron, sulphur, and oxygen are unequal in both sides. Hence,

2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2 (balanced)

4. PCl5 + H2O ---> HCl + H3PO4 (unbalanced)

Atoms of chlorine, hydrogen, and oxygen are unequal in both sides. Hence,

PCl5 + 4H2O ---> 5HCl + H3PO4 (balanced).

From the above balanced equations, it can be observed that; 2Fe + 3H2SO4 ---> Fe2(SO4)3 + 3H2 has the same coefficients in the same order as 2CO2 + 3H20 ---> C2H6O + 3O2

That is, coefficient 2---- 3 ---- 1 ----- 3.

Taking into accoun the law of conservation of matter, the reaction 2 Fe + 3 H₂SO₄ → Fe₂(SO4)₃ + 3 H₂ has the same coefficients in the same order as 2 CO₂ + 3 H₂O → C₂H₆O + 3 O₂

In first place, you have the balanced equation:

2 CO₂ + 3 H₂O → C₂H₆O + 3 O₂

The coefficients of the balanced reaction in order are: 2 -3- 1- 3

The law of conservation of matter states that since no atom can be created or destroyed in a chemical reaction, the number of atoms that are present in the reagents has to be equal to the number of atoms present in the products.

Considering the law of conservation of matter, you must balance the chemical equation.

For that, you must first look at the subscripts next to each atom to find the number of atoms in the equation. If the same atom appears in more than one molecule, you must add its amounts

On the other side the coefficients located in front of each molecule indicate the amount of each compound for the reaction. This coefficient can be modified to balance the equation, just as you should never alter the subscripts.

By multiplying the coefficient mentioned by the subscript, you get the amount of each element present in the reaction.

Considering what was expressed above and the reactions given, the following balanced reactions are obtained:

The coefficients of each balanced reaction in order are:

Finally, the reaction 2 Fe + 3 H₂SO₄ → Fe₂(SO4)₃ + 3 H₂ has the same coefficients in the same order as 2 CO₂ + 3 H₂O → C₂H₆O + 3 O₂

Air pollution is one of the most serious threats facing national parks, harming visitors’ health, clouding scenic views and altering our climate. The air pollution affecting national parks — and the rest of the country — results from the burning of fossil fuels by power plants, oil and gas development, vehicles, agriculture, industrial emissions, and other sources. NPCA works to make sure our nation’s air laws are strong, to hold polluters and government accountable to those laws, and ultimately, to reduce the air pollution that harms our parks, climate and communities.

The Clean Air Act – which has helped improve air quality throughout the nation and the National Park System – is now under consistent threat as the Environmental Protection Agency works to roll back regulations, attack the use of science and offer polluters loopholes. NPCA advocates to defend and strengthen the clean air laws that protect park skies. We speak out for science and guard against policies driven only by politics and private industry.

Picture park skies free of pollution. While this sadly isn’t the case today, NPCA strives to make sure that parks are on the right track and that air pollution harming parks is reduced. We do this by helping to secure strong state plans to limit haze-causing and climate-altering pollution, and by defending existing plans – in court, if necessary.

Clean air laws are meaningless if polluters and the government don’t follow them. NPCA vigilantly monitors for sources that violate their permits or when officials aren’t following through on the safeguards in place to protect parks. We also look for opportunities to collaborate and work in state, local or regional processes to prevent threats of new pollution and help reduce harmful emissions.

Athletes who train short distances and explosive moments of extreme metabolic anaerobiosis have a higher percentage of fast fibers in the muscular structure of skeletal muscles, that is, in the muscles that achieve and carry out locomotion.

Some researchers also argue that men have a predisposition to have more fast fibers than women, since these are predominantly slow fibers.

Rapid muscle fibers to the leg muscle, generating more powerful contractions with less presence of oxygen and greater lactic acidification in the metabolism of the energy currency.

Explanation:

Fast and slow fibers are two different types of fibers, these are usually trained according to the histology or physiology of each athlete.

Those with the highest amount of fast fibers will train and perform better in high-power physical activities, that is, for short distances with little demand for oxygen.

Answer:

negative feedback

Explanation:

When the temperature of the body falls below the normal level, the shivering and surface capillary vasoconstriction that occurs is an example of a negative feedback mechanism of maintaining homeostasis.

The negative feedback mechanism act to counter the process that causes the deviation away from the normal body temperature, the set point. The sensor/receptor which is the skin, in this case, sends information to the control center (part of the brain), the control switch then activates the process of vasoconstriction and muscle shivering to raise the body temperature in case of abnormally low temperature or vasoconstriction and heavy breathing in case of abnormally high temperature.

The entire process is an example of negative feedback in homeostasis.

The model above is an example of negative feedback.

In conclusion, the model above is an example of negative feedback.

The neutrophil is the first line of defense, it is called as PMN OR POLYMORPHONUCLEAR NEUTROPHIL, this cell is said to be the first line of defense for the first to reach the area of ​​infection or in the area of ​​trauma, this upon reaching that area (where it is attracted by defense chemomodulators) it recognizes the bacteria or the foreign body as an antigen, since these do not present the cellular histocompatibility complex of our organism, by recognizing it as an antigen, this cell can detect that it is not something typical of our body but something new that was inoculated, is how this phagocyte to the bacteria and induces its own programmed cell death.

In an injury or infection, the purulent collection is not only debris and pathogenic microorganisms, but they are dead cell bodies of PMNs that induce their own cell death with the battery inside to be able to inhibit its advance in our body, when this phenomenon passes the PMN it is called a peach.

Explanation:

In the event that no antibodies are present, it would not change much if it is the first time that the bacteria enters our body since the formation of antibodies by the lymphocyte cell line occurs as the last stage of immunity (neutrophils appear first, then the antigen presenting cells and finally the lymphocyte lineage in charge of making immunological memory with antibodies).

The PMN are guided more than anything by the humoral factor of the immune response, but the proinflammatory factor like cytokines or leukins, but not by the antibodies, that is why he wrote this process of bacterial assimilation in the response.

Answer:

A. Average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.

Explanation:

The graph in the attachment section portrays the average height of plants (cm) on the y-axis plotted against the concentration of sodium phoshate (mg/L) on the x-axis. Based on the observation of the result in the graph, an increase in the concentration of phosphate caused an increase in the average plant height (as depicted by the upward-sloping line).

However, the plant's average height didn't go beyond 35cm despite an increase in concentration of phosphate. This is because the plants has reached a maximum possible height i.e. a height climax. Hence, they cannot grow taller than 35cm no matter the amount of external nutrients (sodium phosphate) supplied.

Therefore, the noticeable trend that can be used to make a conclusion is that average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.
