Explanation:
Percentage composition tells you the percentage of each element present in a compound or molecule. This allows you to work out the number of atoms of each element present in the molecule. Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound. Percent composition is important because it allows us to determine the percentage of each element that makes up a specific compound.
Answer:
It tells you what the substance is made of.
Explanation:
well ... there are sm common things between solutions and colloids
solutions even and fully mixed together and so are colloids
when we let solutions and colloids settle down both of them do not have boundaries ... the particles of colloids and solutions do not settle down
Both are liquids. Both will pass through filters without seperation.
You can see through a solution, as the ions of the solute are dissolved. A colloid is a suspension of insoluble ultra microscopic particles or large molecules in water or other liquid, kept in suspension by Brownian motion.

Explanation:
The kinetic molecular theory can be used to explain each of the experimentally determined gas laws. The pressure of a gas results from collisions between the gas particles and the walls of the container. Each time a gas particle hits the wall, it exerts a force on the wall. In the kinetic theory of gases, gas molecules move around in the most random way colliding and bumping into each other and then bouncing off in the opposite direction.
The molecules exert no intermolecular forces on each other and they have no potential energy associated with them in their motion.
Thus the energy is wholly kinetic.
The concept of pressure is explained in kinetic theory as a consequence of kinetic energy of gases. Let me explain it.
Consider an ideal gas (the ones with which kinetic theory is concerned) in a closed container.
Due to the troublesome motion of the gas molecules, they will collide with each other, some of them shall collide with the container walls and then bounce back and this process continues.
Adjusting the proportions of substances in an alloy can significantly alter its physical and chemical properties, including hardness, boiling point, physical strength, and resistance to corrosion. These changes can cause phenomena such as rusting or shifting in acidity.
Changing the proportions of substances in an alloy impacts its properties. For instance, changing the ratios of iron, carbon, nickel, and other elements in steel, an alloy, can affect its physical strength and resistance to corrosion. It's crucial to understand that in any alloy, the relative compositions of different elements produce the character of the alloy. For example, in steel, altering the amount of carbon can change the hardness and tensile strength of the final product.
It's also important to know about the law of multiple proportions in chemistry. This law states that when two elements react to form more than one compound, a fixed mass of one element will react with masses of the other element in a ratio of small whole numbers. In alloy formation, these proportions of mass can significantly affect the properties of the resulting alloy.
Physical and chemical properties, such as hardness and boiling point, can be altered by changing the proportions in an alloy. These shifts can lead to both physical or chemical changes, such as melting, freezing, rusting, or even changes in flammability and acidity.

(2) CH3OCH3 (4) CH3CH2CH3
The Correct answer is CH3COOH
The explanation:
when the electrolyte is: A substance that dissociates into ions in solution and acquires the capacity to conduct electricity.
- Electrolyte is actually a compound that dissolves easily in water and creates a solution that becomes a good conductor of electricity.
- The existence of free ions is the reason why the solution becomes a good conductor of electricity.
-The compounds that release small number of free ions on dissolving in water are called weak electrolytes
-and those that release large number of ions are strong electrolyte.
acetic acid partially dissociates in water to form two ions, H+ and CH3COO- , therefore making it a weak electrolyte
