Anaerobic respiration results in the production of 2 ATP molecules.

Anaerobic respiration is the use of electron acceptors other than molecular oxygen in respiration. Despite the fact that oxygen is not the ultimate electron acceptor, the process employs a respiratory electron transport chain. When there is insufficient oxygen for some species to respire, they still require energy to survive. Due to a lack of oxygen, they respire in the absence of oxygen to create the energy they require, which is known as anaerobic respiration. While most aerobic respiration (with oxygen) occurs in the cell's mitochondria, anaerobic respiration (without oxygen) occurs in the cytoplasm.

A) Sodium is the element that will produce a new compound when added to a beaker containing an aqueous solution of copper (II) sulfate ().

When sodium is added to an aqueous solution of copper (II) sulfate, a new compound is formed.

This reaction is known as a displacement reaction and occurs when the sodium ions take the place of the copper ions in the solution.

As the sodium ions bond with the sulfate ions, they form sodium sulfate and free copper ions, which can then be extracted from the solution. This reaction is a great example of how chemical reactions can produce new compounds and materials.

This chemical reaction illustrates how certain substances can interact to create new substances with different properties.

Answer:

Answer:

hope this helps

Explanation:

hydrogen gas

An acid will react with a metal to form a salt and hydrogen gas. The general word equation for the reaction between an acid and a metal is as follows: acid + metal → salt + hydrogen.

Answer:

your answer is B, your graph is constant from there, therefore the pattern is uniform (orderely).

The pressure exerted by a 200 lb man wearing size 10 shoes, if the area of each shoe in contact with the floor is 20 square inches is about 5.77 Pa.

Pressure is the force exerted by unit area. Hence, as the force applied increases, pressure increases.

To calculate the pressure exerted by the man, we need to use the formula:

Pressure = Force / Area

where the force is the weight of the man, and the area is the total area of both shoes in contact with the floor.

First, we need to convert the weight of the man from pounds (lb) to Newtons (N), since the SI unit of force is the Newton. We can do this using the conversion factor:

1 lb = 4.44822 N

So, the weight of the man in Newtons is:

200 lb x (4.44822 N/lb) = 896.44 N

Next, we need to calculate the total area of both shoes in contact with the floor. Since the man is wearing size 10 shoes, we can estimate the area of each shoe to be:

Area per shoe = πr^2 = π(5 in)^2 = 78.54 in^2

So, the total area of both shoes in contact with the floor is:

Total area = 2 x 78.54 in² = 157.08 in²

Now we can calculate the pressure exerted by the man:

Pressure = Force / Area = 896.44 N / 157.08 in²

We need to convert the units of area from square inches (in²) to square meters (m²), since the SI unit of pressure is the Pascal (Pa) and 1 Pa = 1 N/m²:

Pressure = (896.44 N / 157.08 in^2) x (1 m^2 / 1550 in^2) = 5.77 Pa

Therefore, the pressure exerted by the man is approximately 5.77 Pa.

Answer:

52,000 kJ

Explanation:

The combustion reaction is the following:

2 C₂H₆(g) + 7 O₂(g) → 4CO₂(g) + 6H₂O(l)  ΔHm= –3120 kJ

From the chemical reaction and the value of ΔH we can see that 2 moles of ethane gas (C₂H₆(g)) release 3120 kJ of heat energy. So, we have the conversion factor: 3120 kJ/2 moles C₂H₆.

To calculate how many kJ are released from the combustion of 1 kg of ethane, we have to first convert the mass to moles by using the molecular weight (MW) of ethane (C₂H₆):

MW(C₂H₆) = (12 g/mol x 2 C) + (1 g/mol x 6 H) = 30 g/mol

mass = 1 kg x 1000 g/1 kg = 1000 g

moles of C₂H₆= mass/MW = 1000 g/(30 g/mol) = 33.3 mol C₂H₆

Finally, we multiply the conversion factor by the number of moles of C₂H₆ in 1 kg:

heat energy released = 33.3 mol C₂H₆ x 3120 kJ/2 moles C₂H₆ = 52,000 kJ

Therefore, 51,000 kJ are released when 1 kg of ethane is burned.

A fossil that has 6.25% of its carbon atoms is still unstable.

Carbon-14 dating is a method of determining the age of organic material. Measures the amount of carbon-14 (a radioactive isotope of carbon) present in the sample. The half-life of carbon-14 is 5,730 years. This means that after 5,730 years, half of the carbon-14 atoms in the sample have decayed to nitrogen.

If 6.25% of the fossil carbon atoms are unstable, this means that 93.75% of the carbon-14 atoms in the sample have already decayed. To determine the age of a fossil, the following formula can be used:

Age = (half-life x ln(1-(fraction of decayed carbon-14/100))) / ln(2)

Age = ( 5,730 x ln(1 - (93.75/100))) / ln(2)

age = 11,460 years old

c. A fossil in which 75% of the atoms are STABLE.

If 75% of the fossil atoms are STABLE, this means that 25% of the carbon-14 atoms in the sample have decayed. The same formula as above can be used to determine the fossil age. 75 )) / ln(2)

Age = 23,120 years

Please note that these are approximate values, as the actual age of the fossils may be affected by various factors such as contamination, preservation, and measurement error.

It is false that the broad bands or regions located around the nucleus where the electrons are found are called energy rings.

The nucleus is the centre of an atom. Protons and neutrons are particles that make up the nucleus. Shells of electrons rotate around the nucleus. The atom is made up of a small nucleus surrounded by electrons that move. The nucleus includes protons, with a positive charge equivalent to the negative charge of an electron. Neutrons, which have almost the same mass but still no charge as protons, may also be found in the nucleus.

The nuclear powerful force extends long enough from each baryon to bind protons and neutrons together while repelling the repelling electrical force between positively charged protons. The nuclear force acting has a relatively narrow range and practically vanishes just beyond the nucleus's border.

The net ionic equation for the reaction between aqueous sodium fluoride and hydrochloric acid is B. Na+ (aq) + F- (aq) + H+ (aq) + Cl- (aq) → Na+ (aq) + Cl- (aq) + HF (aq)

This is the net ionic equation for the reaction between aqueous sodium fluoride and hydrochloric acid. The balanced equation for this reaction is NaF (aq) + HCl (aq) → NaCl (aq) +HF (aq).

The net ionic equation is derived by canceling out the spectator ions, which are ions that don't participate in the chemical reaction. In this case, Na+ and Cl- are spectator ions, which means that they don't participate in the reaction and are present in the same form on both sides of the equation. Therefore, they are cancelled out, leaving the net ionic equation Na+ (aq) + F- (aq) + H+ (aq) + Cl- (aq) → Na+ (aq) + Cl- (aq) + HF (aq).

108°C is the final temperature of the water after absorption of 1680 Joules of heat energy.

Temperature is a physical quantity used to measure the average kinetic energy of molecules in matter. This is measured with a thermometer or other device that measures the average kinetic energy of the molecules within the substance. The terms Celsius (°C), Fahrenheit (°F), or Kelvin are commonly used to describe temperature (K). Temperature can affect the physical state of matter.

By rearranging the equation gives:

ΔT = q/mc

Plugging in the given values,

ΔT = 1680/ (80.0 g × 4.184 J/g·C)

= 98°C.

Since the initial temperature was 10°C, the final temperature is:

ΔT = T₂ - T₁

98°C = T₂ - 10

Intermolecular force are the force that keep the particles of a substance binded together. Gaseous molecule easily diffuse in air , since the intermolecular attraction is very less in them.

In solid state molecules are densely packed and difficult to move apart. In liquid state , particles have some space to move and in gases molecules are far apart due to less intermolecular force.

As the gas molecules in air absorbs heat energy, they overcome all the intermolecular forces and will spread out in the air. Thus, they rises above over a temperature gradient.
