Answer:

Ok so the first step is glycolysis(which involves 10 different 'steps') which is conducted in the cytosol, so this is where  glucose breaks down  into two molecules of pyruvate.

The breakdown of glucose releases energy which changes ADP to ATP and NAD+ to  NADH.

The second step is commonly known as the Krebs Cycle or Citric Acid Cycle(involves 11 steps). This is where pyruvate is broken down into 3CO2.

The breakdown of pyruvate releases energy which changes ADP to ATP,  NAD+ to NADH and FAD+ to FADH2  

The third step is known as oxidative phosphorylation, this is where energy from NADH and FADH2  is used to generate a H+ gradient, which changes ADP to ATP.

Answer:

Glycolysis, Citric Acid Cycle, and the Electron Transport Chain  

Explanation:

Cellular respiration is the process in which cells break down glucose and release the stored energy to make ATP.

Step 1 — Glycolysis

Glycolysis is the conversion of glucose — a C₆ molecule — into two C₃ (pyruvate) fragments.

Step 1a. The linking reaction — pyruvate oxidation  

In preparation for the second step, each pyruvate ion loses a carbon atom as CO₂ and forms a two-carbon acetyl group.

The acetyl group is transferred to Coenzyme A to produce acetyl CoA.

Step 2 — the Citric Acid Cycle (CAC)

The acetyl CoA enters the CAC.

In various redox reactions, the C atoms in the acetyl group are oxidized to CO₂.

The electrons are passed to energy-storing molecules like NADH and FADH₂.

3. Step 3 — the Electron Transport Chain (ETC)

The NADH and FADH₂ pass their electrons to the Electron Transport Chain

In a series of redox reactions, the electrons reduce oxygen to water.

The energy released converts ADP to ATP (oxidative phosphorylation)

The whole purpose of respiration is to oxidize glucose to CO₂ and water and use the energy produced to form ATP.

One molecule of glucose produces 2 ATP in glycolysis, 2 in the CAC, and 34 in the ETC.

THE SPECIFIC HEAT OF IRON IS 0.714 J/g °C

Explanation:

Heat  absorbed = 1000 J

Mass of the piece of iron = 14 g

Temeperature changes = ( 125-25)°C= 100°C

specific heat of iron = unknown

To find the specific heat of iron in the question use the formula of heat

Heat = mass * specific heat * temperature change

Specific heat = Heat / mass * temperature change

Specific heat = 1000 / 14 * 100

Specific heat = 1000 / 1400

Specific heat = 0.714 J/g °C

So therefore, the specific heat of iron is 0.714 J/g °C

Answer:

the correct answers is "neutralize"

Explanation:

When an acid is related to a base or also called an alkali and they reach a pH of 7, this acid will be neutralized or it will be canceled as the question says.

This happens so it reaches an equilibrium between both compounds, where the solution medium where these two compounds are is NEITHER ACID NOR BASIC, that is why it is called NEUTRAL medium.

Whenever you read that the pH of a solution is balanced, a neutralized acid, or a ph7 it means that the solution is NEUTRAL.

Gases, liquids and solids are all made up of atoms, molecules, and/or ions, but the way the particles inside them differ.

In a gas, the molecules are spread wide apart and moves freely at high speeds

In a liquid, the more closer to each other and will vibrate or slip past each other

In a solid, the molecules are tightly packed, making no room for each other and harder to move. These molecules vibrate and jiggle but, don't move

Answer:

0.25moles

Explanation:

There are 1000[tex]cm^{3}[/tex] for 1[tex]dm^{3}[/tex]

Therefore in 1000[tex]cm^{3}[/tex] of 0.5 mol/[tex]dm^{3}[/tex] solution has = 0.5 moles

Therefore 500[tex]cm^{3}[/tex] contains = 0.5/1000 x 500 = 0.25moles

The number of moles of sulfuric acid in 0.5 mol/dm³ solution is equal to 0.25 mol.

The concentration of the solution can be determined as the number of moles of a solute in per unit volume of a solution is known as molarity or molar concentration.

The Molarity of the solution is calculated in the following formula:

Molarity (M) = Moles (n)/Volume of the Solution (in L)

Now if we have to find the number of moles of solute in the solution, the formula becomes:

Number of moles of solute (n) = Molarity (M) × Volume of the Solution

Given, the concentration of the sulfuric acid solution = 0.5 mol/dm³

The volume of the solution, V = 500 cm³

As we know, 1 dm³ = 10³ cm³, the volume of solution = 0.5 dm³

The number of moles of the sulfuric acid = M × V

= 0.5 × 0.5 = 0.25 mol

Therefore, 0.25 moles of sulfuric acid in 500cm3 of a 0.5mol/dm³ solution of sulfuric acid.

Answer:

ExpPolyploidy is the heritable condition of possessing more than two complete sets of chromosomes. Polyploids are common among plants, as well as among certain groups of fish and amphibians. For instance, some salamanders, frogs, and leeches are polyploids. Many of these polyploid organisms are fit and well-adapted to their environments. In fact, recent findings in genome research indicate that many species that are currently diploid, including humans, were derived from polyploid ancestors (Van de Peer & Meyer, 2005). These species that have experienced ancient genome duplications and then genome reduction are referred to as paleopolyploids. This article discusses the mechanisms underlying polyploidy, and both the advantages and disadvantages of having multiple sets of chromosomes.

Mechanisms of Polyploidy

This diagram shows several pathways by which diploid species can transition to polyploid species and polyploid species can transition to diploid species. Each species is represented by an oval containing two or more colored circles. Each colored circle represents a complete set of chromosomes.

Figure Detail

How does an organism become polyploid? Polyploids arise when a rare mitotic or meiotic catastrophe, such as nondisjunction, causes the formation of gametes that have a complete set of duplicate chromosomes. Diploid gametes are frequently formed in this way. When a diploid gamete fuses with a haploid gamete, a triploid zygote forms, although these triploids are generally unstable and can often be sterile. If a diploid gamete fuses with another diploid gamete, however, this gives rise to a tetraploid zygote, which is potentially stable. Many types of polyploids are found in nature, including tetraploids (four sets of chromosomes), hexaploids (six sets of chromosomes), and other chromosome-pair multiples

Explanation:

The molecules of a substance attract each other.

They are also in constant motion.

Their kinetic energy increases with the temperature.

1. Solids

If the temperature is low enough, the molecules will have little kinetic energy.

They will not be able to escape the attractions of their neighbours, so they will be fixed in place in a crystalline array.

All they can do is vibrate about their position in the array.

The substance will be a solid.

2. Liquids

If the temperature is higher, the molecules will have enough kinetic energy to slide past each other, but not enough to escape the attractions of nearby molecules.

The substance will be a liquid.

3. Gases

If the temperature is high enough, the molecules will have enough kinetic energy to escape from the surface and fly off into space.

The molecules will on average so far apart that they won't feel the attractions of others.

When they do collide, they will have energy to bounce off each other rather than stick together.

The substance will be a gas.

Answer:

El reactivo en exceso es hidrógeno

97.12g NH₃ son formados

Explanation:

Basados en la reacción:

N₂(g) + 3 H₂(g) → 2 NH₃(g)

El hidrógeno pasa de estado de oxidación 0 a estado de oxidación +1. Al perder un electrón se oxida y es el agente reductor.

El nitrógeno pasa de estado 0 estado -3. Al ganar 3 electrones se reduce y es el agente oxidante.

100g de N₂ son (Peso molecular: 28g/mol):

100g × (1mol / 28g) = 3.57 moles de N₂

Y 25g de H₂ son (Peso molecular: 2g/mol):

25g × (1mol / 2g) = 12.5 moles de H₂

Como 3 moles de hidrógeno reaccionan por mol de nitrógeno, las moles de nitrógeno que se necesitan para hacer reaccionar completamente 12.5 moles de hidrógeno son:

12.5 moles H₂× (1 mol N₂ / 3 moles H₂) = 4.17 moles de nitrógeno.

Como hay 3.57 moles de nitrógeno, el reactivo en exceso es hidrógeno.

Como el reactivo limitante es el nitrógeno y 1 mol de nitrógeno produce 2 moles de amoniaco, las moles de amoniaco son:

3.57 moles de N₂ × (2 moles NH₃ / 1 mol N₂) = 7.14 moles de NH₃

La masa producida idealmente es:

7.14 mol NH₃ ₓ (17g/mol) = 121.4 g de NH₃. Como la eficiencia del proceso es del 80%:

121.4 g NH₃ × 80% = 97.12g NH₃ son formados

Answer:

Excess reactant: H₂

Mass of produced ammonia,  97.1 g

Explanation:

Identify the reaction:

N₂ + 3H₂  → 2NH₃

We identify the reducing agent and the  oxidizing agent:

N₂ changed the oxidation state from 0 to -3. This is the reduction, so it is the  oxidizing agent. By the way the H₂ is the reducing agent.

We convert the mass to moles:

100 g / 28 g/mol = 3.57 moles of N₂

25 g / 2 g/mol = 12.5 moles of H₂

Ratio is 1:3. For 1 mol of nitrogen, we need 3 moles of hydrogen

Then, 3.57 moles of N₂ would need (3.57 . 3) / 1 = 10.7 moles

We have 12.5 moles of H₂, so the hydrogen is the excess reactant and the nitrogen is the limiting.

To produce ammonia, the reaction needs 1 mol of N₂, that can produce 2 moles of product

3.57 moles of N₂ will produce (3.57 . 2) / 1 = 7.14 moles of NH₃

As yield reaction is 80%, we will produce 7.14 mol . 0.80 = 5.71 moles

We convert the moles to mass: 5.71 mol . 17 g / 1mol = 97.1 g
