im making a book of chemistry standards for school and im having difficulty drawing a model/explain what a few of them mean. Here are the ones i dont know:
1d.) Students know how to use the periodic table to determine the number of electrons available for bonding
2a.) Students know atoms combined to form molecules by sharing electrons to form covalent or metallic bonds or by exchanging electrons to form ionic bonds.
2b.) Students know chemical bonds between atoms in molecules such as H2,CH4,NH3,H2CCH2,N2 and Cl2 and many large biological molecules are covalent.
2c.)Students know salt crystals, such as NaCl, are repeating patterns of positive and negative ions held together by electrostatic attraction.
3e.) Students know how to calculate the masses of reactants and products in a chemical reaction from the mass of one of the reactants or products and relevant atomic masses.
4a.) Students know the random motion of molecules and their collisions with a surface the observable pressure on that surface.
4b.) Students know the random motion of molecules explains the diffusion of gasses.
4c.) Students know how to apply the gas laws to relations betweenthe pressure, temperature and volume of any mixutre of ideal gases.
5c.) Students know strong acids and bases fully dissociate and weak acids and bases partially dissoctiate.
6b.) Students know how to describe the dissolving process at the molecular level by using the concepts of random molecular motion.
6c.) Students know temperature, pressure and surface area affect the dissolving process
6d.) Students know how to calculate the concentration of a solute in terms of grams per liter, molarity, parts per million and precent composition.
7b.) Students know chemical processes can either release (exothermic) or absorb (endothermic) themal energy.
7c.) Students know energy is released when a meterial condenses or freezes and is absorbed when a material evaporates or melts.
7d.) Students know how to solve problems involving heat flow and temperature changes, using known values or specific heat and latent heat of phase change.
I KNOW ITS A LOT BUT I WOULD APPRECIATE IF YOU HELP ME!
IF THERE ARE ANY SITES WITH EXAMPLES OR HELPS EXPLAIN PLEASE GIVE THEM TO ME!
THANK YOU!!!!!!!!!!!!
