What is the term for the dissolving medium in a solution? (1 point) A. solvent
B. solute
C. solvator
D. emulsifier
Answers
Answer : The correct option is, (A) solvent
Explanation :
Solvent : It is present in large amount. It is a type of substance in which the amount of solute is dissolved.
Solute : It is present in smaller amount. It is a substance that is dissolved in another substance.
Emulsifier : It is a molecule that has two ends, one is water loving end and another is oil loving end. That means it is a substance which stabilizes the emulsion.
Hence, the term for the dissolving medium in a solution is, solvent.
The term for the dissolving medium in a solution is "solvent." It is the component that can dissolve other substances (solute) to form a homogeneous mixture, known as a solution.
The term for the dissolving medium in a solution is "solvent." In a solution, a solvent is the component that exists in the larger quantity and has the ability to dissolve other substances, known as solutes. This process occurs due to the solvent's molecular structure, which allows it to interact with and surround the solute particles, breaking their intermolecular forces and dispersing them evenly throughout the solvent.
Solvents can be liquids (such as water in aqueous solutions), solids (as in solid-state solutions), or even gases (in gas-phase solutions). The choice of solvent depends on the specific application and the nature of the solute. For instance, in chemistry labs, common solvents include water, ethanol, acetone, and more, each chosen based on their compatibility with the substances being studied.
The ability of a solvent to dissolve a solute is influenced by various factors, including temperature, pressure, and the nature of the solute and solvent molecules. The dissolution process is often described in terms of solvation, where solvent molecules surround and stabilize solute particles through electrostatic interactions.
In summary, the solvent is a crucial component of a solution, responsible for dissolving and dispersing solute particles, leading to the formation of a homogeneous mixture. This concept is foundational in chemistry and plays a fundamental role in various scientific, industrial, and everyday applications.

b. Oxygen
c. Hydrogen
d. Nitrogen
Answers
Answer: The correct answer is Option d.
Explanation:
Dry air is composed of a mixture of gases like argon, oxygen, nitrogen, carbon dioxide and many other gases present in trace amount.
The percentage of these gases by volume in dry air is:
Carbon dioxide = 0.03%
Argon = 0.93%
Oxygen = 20.95%
Nitrogen = 78.09%
Hydrogen = Trace amounts
From the above percentage values, we can easily say that nitrogen has the highest percentage by volume in dry air. Hence, the correct option is d.

d. Materials that convert thermal energy into potential energy User: ______ is/are usually the best conductor/s.
a. Metals
c. Air
b. Water
d. Minerals
Answers
Superconductivity is a phenomenon characterized by zero electrical resistance at below critical temperatures. Metals are the best conductors because the molecules inside them are tightly packed, which allows electricity to travel efficiently.
Water is also a good conductor because of the ions and minerals in it. However, water itself is not a conductor of electricity.

Answer:
the same number of electrons in their outermost shells
Explanation:
On the periodic table, elements in the same column have the same number of electrons in their outermost shells (also known as valence electrons), and hence, are said to belong to the same group.
Similarly, elements on the same row in the periodic table have the same number of atomic orbitals and are said to belong to the same period.
The elements in each column have the same number of electrons in their outermost shells.
What is an element of a periodic table?
Elements are defined as the substances in chemistry that can not be broken down by any further chemical reaction.
Typical examples of elements include: oxygen, hydrogen,Helium, calcium, potassium, iron, Chlorine.
These elements are arranged in columns and the rows of the periodic table according to their atomic numbers.
The elements in each column have the same number of electrons in their outermost shells.
