Heres a list of questions

1. Define atom.

Atom is the smallest particle of a substance.

2. What are the subatomic particles found in an atom?

The subatomic particles found in an atom are electrons, protons, and neutrons.

3. Define charged particle.

Charged particle is a particle that has an electric charge.

4. Define electric charge.

Electric charge is the physical property of particles such as electrons and protons. Electric charge causes other particles to experience a force.

5. What are the charged particles found in an atom?

Electrons and protons are the charged particles found in an atom.

6. What are the different types of charged particles?

Charged particles are of two types: positive charges and negative charges.

7. What are the negatively charged particles in an atom?

Electrons are the negatively charged particles in an atom.

8. What are the positively charged particles in an atom?

Protons are the positively charged particles in an atom.

9. What is the mass of an electron?

The mass of an electron is 9.107 × 10-31 kilograms.

10. What is the mass of a proton?

The mass of a proton is 1.672 × 10-27kilograms.

11. Define atomic number.

The total number of protons in the nucleus of an atom is called atomic number.

12. Define neutron number.

The total number of neutrons in the nucleus of an atom is called neutron number.

13. Define mass number.

Mass number is the total number of protons and neutrons in the nucleus of an atom.

Mass number can be mathematically written as

A metabolic pathway that ___ (oxidizes or reduces) an energy-rich source to produce ATP from ADP. Electrons are transferred from

OlgaM077 [116]

Answer:

see explaination

Explanation:

1. A metabolic pathway that OXIDIZES an energy-rich source to produce ATP from ADP.

Oxidation reactions are exergonic and can be coupled to produce ATP from ADP + Pi

2. Electrons are transferred from electron DONORS to compounds with a STRONGER reduction potential.

Electrons are moved from compounds with low reduction potential to compounds with high reduction potential.

3. As electrons move through the electron transport chain, ETC, the energy in the electron is used to pump PROTONS across a membrane.

In respiration, protons are pumped from the mitochondrial matrix to the perimitochondrial space.

4. The pumping of these molecules against their concentration gradient is a form of FACILITATED transport.

Since protons are charged particles, they require a carrier protein for their transport. The movement of these molecules back into the cell (down their concentration gradient) releases energy which the cell couples to the formation of ATP.

6. The energy in PHOTON/LIGHT is absorbed by an electron in a photocenter. This energy is converted from light energy into chemical energy into kinetic energy as the energized electron is used in back to back REDOX reaction in the electron transport chain, ETC.

7. The ETC creates A PROTON GRADIENT which is used by the cell to power the formation of ATP.

8. In CYCLIC ELECTRON TRANSPORT, the electron returns to the photocenter.

9. In NON-CYCLIC photosynthesis the electron reduces NADP+ to form NADPH.

What are dipoles, and what is the difference between a natural dipole and an induced dipole?

Tasya [4]

Answer:

See explanation below.

Explanation:

Dipoles are molecules that have partial charges. It happens because of the difference in electronegativity of the elements. This property is the tendency that the atom has to take the electron to it, so, in the covalent bond, the shared pair of electrons is easily found at the more electronegativity atom, and so, it has a partial negative charge, and the other, a partial positive charge. This is a natural dipole.

If the difference of electronegativity is 0, or extremely close to 0, then the molecule is nonpolar, and so the molecule doesn't have partial charges. But, to be joined together and form the substance, the partial charge must be induced, so it's an induced dipole.

Explain how the Law of Conservation of Mass is demonstrated In photosynthesis and cellular Respiration chemical equations. (Less

Oksi-84 [34.3K]

Explanation:

According to the law of conservation of mass, In a chemical reaction, mass is neither created nor destroyed. In other words, the total mass for the reactants needs to equal the total mass of the products.
In photosynthesis the reactants are 6 carbon dioxide, 6 water and sunlight. The mass of these reactants adds to equal the mass of the products, which are 1 glucose and 6 oxygen.
Cellular respiration on the other hand uses glucose and oxygen gas to produce water, carbon dioxide, and a usable form of energy known as ATP.
Cellular respiration is the opposite of photosynthesis, such that the products of photosynthesis are the reactants of cellular respiration. Cellular respiration also obeys the law of conservation of mass.
