There are two factors that tell you if a change can occur spontaneously. 1) if the change gives off heat energy when it occurs or absorbs heat energy when it occurs. 2) if the change results in particles becoming more disordered. Lower energies are more stable than higher energies. Everything tends to become more disorganized […]Read more "4.7 enthalpy chem talk"
Substances that dissolve in water that can conduct electricity are called electrolytes. This is why electrolyte water can restore energy in a person and is healthy for you as an alternative to extremely sugary drinks like gatorade. For a solution to conduct electricity there are two things that need to happen, 1) There must be […]Read more "4.6 chem talk"
A mole is a counting word used to count large amounts of small objects such as atoms and molecules. It is like a person using a dozen to count donuts. To find a mass of a compound you have to take the molar masses of every atom in the compound and add it up to […]Read more "4.3 chem talk"
Polarity comes from uneven partial charge distribution from atoms in a compound. It is the weakest intermolecular force, this happens when electrons occupy positions that make the atoms form temporary dipoles. C7H16 BRead more "5.2 chem talk Checking Up questions 1, 2, and 3 and Chem to Go question 4"
In a solid particles are unable to move around with barely any freedom because their attraction to each other is very strong, this force is called an intermolecular force. These forces are electrical forces because they are related to the number and position of electrons. To break these bonds solids can be heated until the […]Read more "Chem talk chapter 5 section 2"
In organic chemistry atoms can bond with each other without outside help. This can create large and super complex things. Isomers are compounds with the same formula but different structures. This means that multiple carbon atoms that are exactly the same can form different things, instead of forming the same thing every time. Lewis dot […]Read more "Chapter 7 section 8 chem talk"
It means it occurs out of nowhere (no cause) If the change gives off heat energy, and if the change results in particles becoming more disordered. If the system releases heat energy to the surroundings or absorbs energy. From the system. Powdered iron and more surface area. It provides a lower energy alternative pathway for […]Read more "Chem checking up 4.6"
Majority of the metals on the periodic table are metals. Metals conduct electricity, while some do a much better job than others metals are still known to all conduct electricity. Since most metals can withstand high temperatures they are used to make buildings and large construction projects. Most of these metals though do not occur […]Read more "4.4 Chem talk"
Out of the thousands and thousands of reactions that occur in the world majority of them occur in water or aqueous solutions. There are some rules that can help you predict the products of precipitation. An ionic compound is soluble if a large amount of it dissolves in water. The amount that represents the “large […]Read more "3.6 Chem talk"
Valence electrons and the octet rule: The chemical reactivity that we saw happen during our experiments was because of the valence electrons in the metals we experimented with. The valence electrons exist on the outermost part of the atom, when we did these experiments the metals lost their valence electrons to other materials. The best way […]Read more "3.3 Chem Talk"
