When glucose is totally oxidized to CO2 and H2O, how many ATP molecules are made by oxidative phosphorylation out of a maximum yield of how many ATP molecules?

Answers

Answer: 26 out of 30.

Explanation:

Out of 30 ATP molecules, 26 are produced from maximum oxidative phosphorylation production. Two more come from glycolysis and two more are from the citric acid cycle.

To power other cellular processes, ATP captures and releases chemical energy obtained from the breakdown of food molecules.

You are eating dinner with your familiy one night. Your little brother (Who is a disgusting monster ) asked if you likes "seafood?" When you said yes, He proceeded to show you his chewed up, or "See Food". Did a chemical reaction take place, yes or no? What evidence or lack of evidence do you have to support your answer?

Answers

Answer:

yes eating the food involves both physical and chemical changes. The chewing of food is a physical change, while the mixing of saliva with food triggers chemical reactions

Explanation:

Once the food mixes with the saliva in our mouth, chemical reactions start taking place in the food, leading to its breakdown and changes in its chemical composition. An evidence of the chemical changes is the taste that we feel when we eat something sweet or sour etc.

What of these should Hailey include in her list?

Synthetic polymers are biodegradable.
Synthetic polymers are not flexible.
Synthetic polymers are recycled cheaply.
Synthetic polymers are inexpensive to produce.

Answers

Answer:

Hailey should add, they are inexpensive to produce.

Explanation:

Reason being why they are inexpensive to produce, is due to them being chemical based and easy to product in the factory setting. Which makes them extremely cheap to make.

Reason being why the others are wrong, synthetic polymers are not biodegradable as they are made in a factory with oils. Synthetic polymers are not flexible due to them being used for harder products. Synthetic polymers are not recycled cheaply as they are made with chemicals which makes it very hard to recycle.

bigger size elements have low ionization energy and high shielding effect .justify the statement

Answers

Bigger size elements have low ionization energy and high shielding effect because:

Shielding effect:This effect describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. The more electron shells there are, the greater the shielding effect experienced by the outermost electrons.When shielding effect decreases the attraction force exerted by the nucleus increases on valence electrons.As a result, atoms will be larger.

determine the number of charged particles in nucleus of calcium atom then deduce the number of electrons
NUCLEAR CHARGE (20+)
ATOMIC MASS (40 amu)
given the relative charge of a proton =1+\ m1nucleon=1amu

Answers

Answer:

detail is given below.

Explanation:

The charged particles of nucleus are protons while neutrons are neutral having no charge.

We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus.

Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.

Symbol of proton= P⁺  

Symbol of neutron= n⁰  

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons.

one proton contribute 1 amu to the total weight. There are 20 protons and 20 neutrons in Ca thus its atomic mass is 40 amu.

While the atomic number is 20.

Please if you don't know don't answer​

Answers

Answer:

Mass = 50kg, a = 20m/sec^2

F = MA

F = 50 * 20

F = 1000N

F = MA

650 = M * 10

M = 650/10 = 65kg

The phenomenon of weightlessness occurs when there is no force of support on your body. when your body is effectively in free fall, accelerating downward at the acceleration of gravity, then you are not being supported.

F = Gm1m2/distance^2

F = 6.6726* 10 ^-11 * 70 * 5.98 * 10^24/(6.38 * 10^6)^2

AB + energy→ A +B

23.
The general equation shown is a reaction that is an

a. exothermic decomposition
b. endothermic decomposition
c. endothermic synthesis
d. exothermic synthesis

Answers

Answer:

b. endothermic decomposition

Explanation:

Decomposition reaction:

It is the reaction in which one reactant is break down into two or more product.

AB → A + B

Synthesis reaction:

It is the reaction in which two or more simple substance react to give one or more complex product.

A + B      →      AB

Endothermic reactions:

The type of reactions in which energy is absorbed are called endothermic reactions.

In this type of reaction energy needed to break the bond are higher than the energy released during bond formation.

For example:

C +  H₂O  + 131 kj/mol  →  CO  + H₂

Thus, in given reaction energy is added and AB compound is decomposed to give A and B so this reaction is endothermic decomposition.

Answers

Equally importantly, photosynthesis is the source of oxygen and also removes carbon dioxide from our atmosphere. Oxygen is required for cellular respiration, the process by which food is broken down into energy.

Without photosynthesis there would be no oxygen in the earth's atmosphere and we wouldn't be here!

According to Le Chatelier's principle, what happens to the equilibrium constant (K) when the concentration of the reactants is doubled? The value of the equilibrium constant (K) is doubled. The value of the equilibrium constant (K) is halved. The value of the equilibrium constant (K) remains the same. The value of the equilibrium constant (K) changes unpredictably.

Answers

Answer:

The value of the equilibrium constant (K) remains the same.

Explanation:

A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.

At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.

Answers

Answer:

0.105 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\[/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{6.34 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.105315...[/tex]

We have the final answer as

0.105 moles

What is the similarity between teeth and eggshells?

Answers

Explanation:

Because they share a similar composition, similar chemicals affect their structures in positive or negative ways. For example, fluoride – a staple in many dental practices – strengthens both enamel and eggshells and helps protect them from acids. Acids weaken and break down both substances. Scientists find this particularly concerning given that the ocean is growing increasingly acidic. They fear this may weaken the eggs of some marine species and harm their chance of survival. Most dentists recommend limiting aggressively acidic foods and beverages such as soft drinks.

Eggshells have a similar chemical composition to our tooth enamel, making them react similarly with other chemicals. This can help us understand what stains tooth enamel. When we brush an eggshell with fluoridated toothpaste, it strengthens the shell and protects it from acid, just like it does for our tooth enamel.
