Answer:
X
Explanation:
Letter X is mitochondria. The mitochondria produces carbon dioxide, water, and ATP energy during cellular respiration.
It is impossible to divide an atom into smaller parts.
There are electrically neutral particles inside atoms.
Atoms contain small, negatively charged particles.
Answer: The correct statement is atoms contain small, negatively charged particles.
Explanation:
J.J.Thomson was a scientist which discovered electrons that are present in an atom.
He did an experiment and gave a model for this. The experiment conducted by him was Cathode Ray experiment and the model given by him was Plum pudding model.
From cathode ray, he showed that the cathode ray was composed of a negatively charged particles and named it as electrons. From plum pudding experiment, he said that the electrons are embedded in the atom. These particles carry negative charge and are very small as compared to the atom.
Hence, the correct statement is atoms contain small, negatively charged particles.
(2) It has a charge of +13 and is surrounded by a total of 13 electrons.
(3) It has a charge of –13 and is surrounded by a total of 10 electrons.
(4) It has a charge of –13 and is surrounded by a total of 13 electrons.
The nucleus of an aluminum atom has a charge of + 13 and is surrounded by a total of 13 electrons. Therefore, option (2) is correct.
Aluminum is a chemical element with atomic number 13 and the chemical symbol Al. Aluminum has 13 protons in its nucleus so it has +13 charge on its nucleus and thirteen electrons surrounding the nucleus of the aluminum.
Aluminum element has a low density and has a great affinity towards oxygen and forms a protective layer of oxide when exposed to air.
Aluminum is a post-transition metal placed in the p-block of the periodic table and forms compounds in the +3 oxidation state. The aluminum cation (Al³⁺) is polarizing in nature and forms metallic bonds to get its covalency in aluminum foil.
The atomic number of the aluminum atom is 13 therefore it has 13 electrons and 13 protons in its atom. The 13 electrons are present n the nucleus of an atom so the nucleus is positively charged.

Answer:
I will pick fusion over fission.
Explanation:
Fission and Fusion are nuclear processes in which atoms are altered to create energy.
By definition, fission is simply the division of one atom into two atoms while fusion is simply the combination of two lighter atoms to produce a bigger atom.
I will pick fusion over fission for the following reasons;
- Fusion reactions produces far greater amounts of energy than fission reactions normally produce.
- Fusion does not produce radioactive, toxic waste products that can damage the environment we live whereas fission does so.
Answer:
Yes, this reaction will be spontaneous.
Explanation:
A reaction is spontaneous if ΔG < 0.
The coupling of glycerol to glycerol-3-phospate with ATP gives:
glycerol + HPO₄²⁻ ⟶ glycerol-3-phosphate + H₂O ΔG = +9,2 kJ/mol
ATP + H₂O ⟶ ADP + HPO₄²⁻ ΔG = -30,5 kJ/mol
glycerol + ATP ⟶ ADP + glycerol-3-phosphate
ΔG = +9,2 kJ/mol - 30,5 kJ/mol = -21,3 kJ/mol
As ΔG<0, this reaction will be spontaneous
I hope it helps!
Answer;
Yes; this reaction be spontaneous if coupled with the hydrolysis of ATP.
Explanation;
The reaction converting glycerol to glycerol-3-phosphate (energetically unfavorable) can be coupled with the conversion of ATP to ADP (energetically favorable):
Glycerol + HPO42 ⟶glycerol-3-phosphate+H2O
ATP + H2O⟶ ADP + HPO42− + H+
The property best used when determining the strength of an ionic bond in a solid is:
LATTICE ENERGY
The lattice energy is the energy released during the deposition of gaseous ions of opposite charges. Deposition is the transformation of gas to solid.
Explanation:
The main types of solids are ionic, molecular, covalent, and hard. Ionic solids consist of absolutely and negatively energized ions held concurrently by electrostatic forces; the power of the bonding is indicated in the lattice energy. Ionic solids manage to have high melting points and are fairly hard. lattie energy is a stratagem of the energy received in the crystal lattice of a compound, similar to the energy that would be delivered if the element ions were produced together from infinity.

A. lattice energy
