What does the nucleus of an atom include? - Answer-protons and neutrons The number of protons usually determines what? - Answer-the atomic number and charge of an atom Covalent bond - Answer-formed when atoms share electrons Ionic bond - Answer-formed when an atom transfers an electron to another atom Matter - Answer-refers to substances that have mass and occupy space (or volume), there are three states (solid, liquid, and gas) Conservation of matter - Answer-explains why chemica...

CHM2210L Midterm Exam Practice Questions and Answers 100% Pass Do all mixtures of two different organic compounds exhibit a broad melting point range? - ANSWER- No, eutectic mixtures(minimum mp for a mixture) melt with a sharp mp range. Do organic compounds that exhibit polymorphism have different melting points? - ANSWER-Yes, variations in the intermolecular attraction of different crystalline forms can cause polymorphs to have different but sharp mp What might you observe when an organi...

Matter Anything that has mass + volume divisions of matter pure substances and mixtures Pure Substance A sample of matter, either a single element or a single compound, that has definite chemical and physical properties EX: O, H, CL, ( elements ) Compounds: H20, NaCL definite properties: always the same Heterogenous mixtures are... mixtures that are not uniform throughout Oil and water - creating a distinct boundary Homogenous mixture example a mixture in which the composition is...

what are physical differences that elements or compounds may have solubility mp/bp particle size or mass what is the difference between a miscible liquid and an immiscible liquid -miscible mix well with another to form a homogenous solution immiscible liquids cannot mix to give single phase. eg. water and oil as oil floats on top of water What is decantation? -process to seperate mixtures by removing a liquid layer that is free of a solid or another liquid can be used to seperate mixtu...

CHEM120 Week 4 Concepts: The Ideal Gas Laws and Acid/Base Reactions- Download To Score An A+ PHYSICAL STATES OF MATTER In this section, we will discuss the Ideal Gas Laws. First, we will review the properties of solids, liquids, and gases. Second, we will discuss the kinetic-molecular theory of gases, which explains why they are so unique compared to other states of matter. Finally, we will discuss gas law equations, and practice using them to solve for different parameters. This unit has many s...
