What is the process that changes one set of chemicals into another set of chemicals?a. cohesion
b. hydrogen bonding
c. chemical reaction
d. dissolving
Answers
The process that changes one set of chemicals into another set of chemicals is called a chemical reaction. The correct answer is option c.
A chemical reaction is a process in which chemical bonds between atoms and molecules are broken and formed, resulting in the creation of new substances with distinct chemical properties.
In a chemical reaction, the reactants are the starting substances that react with each other, while the products are the new substances that are formed.
For example: When hydrogen gas reacts with oxygen gas in the presence of a spark or flame, a chemical reaction occurs that produces water as a product:
Therefore, a chemical reaction is the process of transforming one set of chemicals into another set of chemicals. Option c is the correct answer.

Cohesion would be the process that changes one set of chemicals into another set of chemicals, as the reactants bond to bring the product, aka product(s).

According to the nuclear fission and nuclear fusion reactions,energy from fusion cannot yet be converted to electricity.
What is nuclear fission and nuclear fusion?
There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Fusion results in a lot of energy. The sun uses fusion reactions to burn. So, if we were using fusion reactions, we would have little suns going off. Nuclear bombs often use a combination of fission and fusion reactions to maximize devastation. However, we do not currently have the ability to control or convert the energy produced by a fusion reaction.

Buffer capacity is defined as the capacity of a buffer to resist changes in pH upon addition of an acid or a base. The buffer capacity is high when the concentration of the acid and its conjugate base is high, and the pH of the solution is near the pKa value of the weak acid.
The greater the buffer capacity, the better it can resist pH changes upon addition of an acid or base. The buffer capacity of a solution is highest when the pH is near the pKa value of the weak acid.
A buffer is a solution that has the ability to resist changes in pH upon the addition of an acid or base. The buffer capacity is highest when the pH of the buffer is close to the pKa of the weak acid component in the buffer. Therefore, the buffer capacity is the highest when the pH is equal to the pKa value of the weak acid.
Therefore, the solution with the greatest buffer capacity is the one with the highest concentration of both the weak acid and its conjugate base, which can resist the changes in pH with the addition of an acid or base.

Answer:
Strength
Explanation:
Lattice energy is the energy needed to remove one mole of ionic substance to its gaseous ion.
The lattice energy is used to determine the strength of a substance.
- Lattice energy increases as the size of an ion decreases.
- It decreases as the ion size increases.
- This quantity is often determined using electrostatics method in the laboratory
- The lattice energy is used to break an ionic solid to form a gaseous compound.
Lattice energy is an estimate of the strength of the bond because lattice energy is a measure of the strength of the electrostatic forces holding ions together in an ionic compound's crystal lattice. So the correct option is D.
D. strength
Lattice energy is the energy required to completely separate one mole of an ionic compound into its individual gaseous ions. In other words, it measures the strength of the forces that hold the ions together in the crystal lattice. Lattice energy is typically expressed in energy units per mole, such as kilojoules per mole (kJ/mol).
Factors Influencing Lattice Energy:
1. Charge of Ions: Greater charge on ions leads to stronger attractions and higher lattice energy.
2. Ionic Radius: Smaller ionic radii lead to higher lattice energy. When ions are smaller, they can get closer to each other in the crystal lattice, resulting in stronger electrostatic attractions.
3. Distance between Ions: Lattice energy increases as the distance between ions decreases. Closer ions experience stronger attractions.
4. Electron Configuration: The arrangement of electrons affects the effective nuclear charge felt by the ions. Ions with more stable electron configurations (e.g., noble gas configurations) have higher lattice energies.
Lattice energy plays a crucial role in determining the stability and properties of ionic compounds. It influences properties such as melting and boiling points, hardness, solubility, and the overall stability of the compound. Compounds with higher lattice energies tend to have higher melting points and are less likely to dissociate into ions in solution.
Therefore, lattice energy is a measure of the strength of the electrostatic forces holding ions together in an ionic compound's crystal lattice. It's influenced by factors such as ion charges, ionic radii, and distance between ions.
