Answer:

1.68 atm (if temperature is constant)

Explanation:

p1 * v1 = p2 * v2

1 * 2.85 = p2 * 1.70

2.85 / 1.70 = p2

p2 = 1.6764

There are so many gas laws like Charles's law, Avogadro’s law and many more, out of which Boyle's law is one of the most important law among all gas laws. The pressure is required to compress the balloon to a volume of 1.70L is  1.6764 atm.

According to Boyle's law pressure is inversely proportional to volume at constant Temperature. It is applicable only on the ideal gases. Since temperature is constant here, we can apply this law.

Mathematically

P₁V₁=P₂V ₂

P₁= initial pressure of balloon =1.0atm

V₁= initial volume balloon =2.85L

P₂=final pressure balloon =?

V ₂=final volume balloon =1.70L

Putting all values

1 × 2.85 = P₂×1.70

2.85÷ 1.70 = P₂

P₂ = 1.6764 atm

Therefore, the pressure is required to compress the balloon to a volume of 1.70L is 1.6764 atm.

Answer:

C4H9

Explanation:

If H = 15.88%

Then C = 100.00 – 15.88 = 84.12

Divide each % value by respective atomic mass

H = 15.88/1 = 15.88

C = 84.12/12 = 7.01

Divide through by smaller value

H = 15.88/7.01 = 2.26

C = 7.01/7.01 = 1

Remove fraction , multiply by 4

H = 9

C = 4

Empirical formula = C4H9

The hydrocarbon could be ( C4H9)2 = C8H18 = octane.

The volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide is 0.15L

The reaction of sulphuric acid and sodium hydroxide is expressed as:

[tex]2NaOH + H_2SO_4 ==> Na_2SO_4 + 2H_2O[/tex]

Determine the moles of NaOH present

Molar mass of NaOH = 23 + 16 + 1 = 40g/mole

Given that mass of NaOH is 75.0g

Mole of NaOH = 75/40  = 1.875moles

Determine the number of moles [tex]H_2SO_4[/tex] needed to react with 1.875 moles NaOH

Moles of [tex]H_2SO_4[/tex] = [tex]\frac{1.875}{2} = 0.9375moles of H_2SO_4[/tex]

Recall that volume = Molar mass * number of moles

Volume of [tex]H_2SO_4[/tex] =  0.160 * 0.9375

Volume of  [tex]H_2SO_4[/tex] = 0.15L

Hence the volume of 0.160 M sulfuric acid necessary to react completely with 75.0 g sodium hydroxide is 0.15L

Answer:

In the previous section, we discussed the relationship between the bulk mass of a substance and the number of atoms or molecules it contains (moles). Given the chemical formula of the substance, we were able to determine the amount of the substance (moles) from its mass, and vice versa. But what if the chemical formula of a substance is unknown? In this section, we will explore how to apply these very same principles in order to derive the chemical formulas of unknown substances from experimental mass measurements.

Explanation:

tally. The results of these measurements permit the calculation of the compound’s percent composition, defined as the percentage by mass of each element in the compound. For example, consider a gaseous compound composed solely of carbon and hydrogen. The percent composition of this compound could be represented as follows:

\displaystyle \%\text{H}=\frac{\text{mass H}}{\text{mass compound}}\times 100\%%H=

mass compound

If analysis of a 10.0-g sample of this gas showed it to contain 2.5 g H and 7.5 g C, the percent composition would be calculated to be 25% H and 75% C:

\displaystyle \%\text{H}=\frac{2.5\text{g H}}{10.0\text{g compound}}\times 100\%=25\%%H=

10.0g compound

iii) Malate dehydrogenase in the cytoplasm oxidizes malate to oxaloacetate.

iv) Phosphoenolpyruvate carboxykinase decarboxylates and phosphorylates oxaloacetate.forming phosphoenolpyruvate.  

Explanation:

Gluconeogenesis is the synthesis of glucose from non - carbohydrate compounds. The substrates for gluconeogenesis are lactate, pyruvate, amino acids, propionate and glycerol.

Gluconeogenesis occurs only in cytosol but the precursor is produced in mitochondria. In the conversion of pyruvte to phosphoenolpyruvate occur in mitochondria and cytosol.

Step -1:

Pyruvate carboxylase is a biotin dependent enzyme located in mitochondria. It converts pyruvate to oxlaoacetate and carbondioxide in the presence of ATP.Oxlaocetate synthesized in mitochondrial matrix has to be transported to cytosol for gluconeogenesis. Oxaloacetate is impermeble, cannot be sent out of mitochondria. So it has to be converted to malate.

Step -2:

Malate dehydrogenase in mitochondria converts oxaloacetate synthesized in mitochondrial matrix to malate. And then  it is transported to cytosol.

Step 3:

Malate dehydrogenase responsible for reversible reaction in cytosol converts malate to oxaloacetate.

Step -4

Phosphoenolpyruvate carboxy-kinase in cytosol converts oxaloacetate to PEP. The enzyme transfer high energy phosphate bond from GTP to oxaloacetate to from PEP and liberated carbondioxide.

Therefore, the steps of glycolysis converts phosphoenolpyruvate to pyruvate are as follows.

i) In thee mitochondrion, pyruvate carboxylase converts pyruvate to oxloacetate.

ii) Malate dehydrogenase in the mitochondrion reduces oxaloacete to to malate.

iii) Malate dehydrogenase in the cytoplasm oxidizes malate to oxaloacetate.

iv) Phosphoenolpyruvate carboxykinase decarboxylates and phosphorylates oxaloacetate.forming phosphoenolpyruvate.

Answer:

Towards the products

Explanation:

The equilibrium constant for the reaction is 14. The equilibrium will shift towards the product.

Equilibrium is defined as a condition in which the forward and backward reaction rates are identical. When all of the external forces acting on an object are balanced, the object is said to be in equilibrium in a reference coordinate system. This indicates that all external forces and moments acting on this item have a net effect of zero.

When sulfur dioxide SO2 concentration is increased, the Q value rises to 1.4.

Q = [ SO₃ ]² / [ SO₂ ]² [ O₂ ]

Q = 1.4

Where K

K = [ SO₃ ]² / [ SO₂ ]² [ O₂ ]

K = 14

Q will shift to the right to consume the extra SO2 and restore the equilibrium position since Q is less than K.

Thus, the equilibrium constant for the reaction is 14. The equilibrium will shift towards the product.

Answer:

Gas>Liquid>Solid

Explanation:

Entropy by definition is the degree of randomness in a system. If we look at the three states of matter: Solid, Liquid and Gas, we can see that the gas particles move freely and therefore, the degree of randomness is the highest.

As the reaction goes through phases, the phase that has the highest entropy is the gas state. This is further explained below. Option A is correct.

A thermodynamic number that represents the inability of a system's thermal energy to be converted into mechanical work, and is commonly understood as the system's degree of disorder.

In conclusion, we have that as the reaction goes through phases, the gaseous state has the highest entropy.

Explanation:

Fusion processes require fuel and a confined environment with sufficient temperature, pressure, and confinement time to create a plasma in which fusion can occur. The combination of these figures that results in a power-producing system is known as the Lawson criterion. In stars, the most common fuel is hydrogen, and gravity provides extremely long confinement times that reach the conditions needed for fusion energy production. Proposed fusion reactors generally use hydrogen isotopes such as deuterium and tritium (and especially a mixture of the two), which react more easily than hydrogen to allow them to reach the Lawson criterion requirements with less extreme conditions. Most designs aim to heat their fuel to around 100 million degrees, which presents a major challenge in producing a successful design.

As a source of power, nuclear fusion is expected to have many advantages over fission. These include reduced radioactivity in operation and little high-level nuclear waste, ample fuel supplies, and increased safety. However, the necessary combination of temperature, pressure, and duration has proven to be difficult to produce in a practical and economical manner. Research into fusion reactors began in the 1940s, but to date, no design has produced more fusion power output than the electrical power input.[1] A second issue that affects common reactions is managing neutrons that are released during the reaction, which over time degrade many common materials used within the reaction chamber.

Fusion researchers have investigated various confinement concepts. The early emphasis was on three main systems: z-pinch, stellarator, and magnetic mirror. The current leading designs are the tokamak and inertial confinement (ICF) by laser. Both designs are under research at very large scales, most notably the ITER tokamak in
