Explanation :
Physical property : It is defined as a change in which the identity of substance does not change.
Physical change : It is defined as something observed while keeping the identity of the substance the same.
Homogeneous mixture : It is defined as something made up of at least two different substances and is usually very difficult to separate. Even distribution of particles.
Heterogeneous mixture : It is defined as something made up of at least two different substances and easily separated by physical means. Unequal distribution of particles.
Chemical property : It is defined as something observed by changing the identity of a substance.
Compound : It is defined as a pure substance made up of at leat two different elements.
Matter : It is defined as anything that has matter and takes up space.
Chemical change : it s defined as a change that creates a new substance or compound.
Extensive property : It is defined as a property that change with the amount of matter present.
Mass : It is defined as the amount of matter contained in an object.
Volume : It is defined as the amount of space a substance takes up.
Intensive property : It is defined as a property that does not change with the amount of matter present.
Answer:
A. Atoms randomly crashing into each other
E. The force of one object pushing against the force of another object.
Explanation:
Forces can be classified into two categories based upon the the mode of transfer or application:
1. Contact forces
2. Non-contact forces
Contact forces are the ones which require the physical contact of the matter to get transferred and tend to create the affect. Whereas non-contact forces have the field property which transfers the affect of force from one point to another without any physical contact of the matter or the medium.
- Atoms crashing onto each other have some mass and velocity which upon collision impacts the other atoms exerts a contact force.
- The interaction between the charged particles due to their charges is always due to the electric field be it electron or proton, be it within an atom or out of an atom.
- The force between any two objects pushing or pulling each other is also possible only due to contact.
Answer:
It's about mass of 40.1⋅g

I hope this helps you out. Have a nice day!
A) Compounds because its the other word of the formation of new substances!
Molarity is the molar concentration of the chemical species of the solute dissolved in the solvent. The molarity of the solution when diluted is 0.0257 M.
<h3>What is the relation between molarity and dilution?</h3>
The molar concentration or the molarity of the solution is inversely proportional to the dilution. An increased dilution will decrease the molarity of the solution.
The molarity is given by:
Also, it can be shown as:
Given,
= 0.513 M
= 25 mL
= ?
= 500 mL
Substitute value in the equation as:
Therefore, 0.0257 M is the molarity after dilution.
