What does PMS stand for in solubility rules?
PMS (Purple Mushrooms Stink): - P → Lead (Pb) - M → Mercury (Hg) - S → Silver (Ag)
chemistry solubility -
What ions are included in Castro Bear?
Castro Bear: - Ca²⁺ - Sr²⁺ - Ba²⁺
chemistry solubility -
What is the solubility status of carbonates, phosphates, chromates, and sulfides?
All are insoluble except for: - Group 1 - Ammonium (NH4+)
chemistry solubility -
Which hydroxides are soluble?
Hydroxides are insoluble except for: - Group 1 - Strontium (Sr²⁺) - Barium (Ba²⁺) - Ammonium (NH4+)
chemistry solubility -
Which sulfides are soluble?
Sulfides are insoluble except for: - Group 1 - Group 2 - Ammonium (NH4+)
chemistry solubility -
What is the solubility of cyanide?
Cyanide is only soluble with: - Group 1 - Calcium (Ca²⁺)
chemistry solubility -
What happens when PMS reacts with sulfate or group 17?
When PMS reacts with sulfate or group 17, it becomes insoluble.
chemistry solubility -
What happens when Castro Bear reacts with sulfates?
When Castro Bear reacts with sulfates, it becomes insoluble.
chemistry solubility -
What are the exceptions to the solubility rules for sulfates?
Sulfates are generally soluble except when reacting with: - PMS - Castro Bear
chemistry solubility -
What are the requirements for a successful chemical reaction?
- Molecules must collide
- Correct orientation of collision
- Sufficient activation energy
chemistry reactions -
What is the reaction formula for the given example?
AB + CD → AD + CB
chemistry reactions -
What happens when there is not enough activation energy?
Bonds do not break: 00 + 00 → 0000
chemistry activation_energy -
What happens when there is sufficient activation energy?
Bonds break: 00 + 00 → 800
chemistry activation_energy -
How does the activation energy for exothermic reactions compare to endothermic reactions?
Activation energy for exothermic is less than for endothermic.
chemistry energy -
What is the rate of reaction?
Rate at which reactants decrease or products increase.
chemistry kinetics -
What are the factors influencing the rate of reaction?
- Surface area
- Concentration
- Temperature
- Pressure (if gases)
chemistry factors -
What does the diagram show about potential energy vs reaction progress?
It illustrates exothermic and endothermic reactions with activation energy, reactants, products, and energy changes.
chemistry diagrams -
How does surface area affect the rate of reaction?
Increasing surface area leads to more collisions, increasing the rate of reaction.
chemistry reaction_rate -
What happens to the rate of reaction when concentration increases?
The rate of reaction increases with higher concentration.
chemistry reaction_rate -
How does temperature affect the rate of reaction?
Increasing temperature increases the rate of reaction.
chemistry reaction_rate -
What happens to the rate of reaction when temperature increases?
The rate of reaction increases due to more kinetic energy, leading to more collisions among molecules.
chemistry temperature -
How does pressure affect the rate of reaction for gases?
When pressure increases, the rate of reaction increases.
chemistry pressure -
What happens to volume when pressure increases?
When pressure increases, the volume decreases.
chemistry pressure -
What is the role of a catalyst in a chemical reaction?
A catalyst increases the rate of reaction by decreasing the activation energy.
chemistry catalyst -
What is shown in the image with two test tubes?
The first test tube shows no reaction; the second shows a reaction with bubbles and is labeled 'heat'.
chemistry reaction -
What is illustrated in the image with two beakers?
One beaker is heated, which increases the reaction rate.
