Acids and Bases
An acid is a substance that produces this in aqueous solution.
What are positive hydrogen ions?
This kind of reaction feels warm or hot to the touch.
What is an exothermic reaction?
This is a measure of how much solute is in a given amount of solvent
What is concentration?
This is the average speed of particles in a substance.
What is temperature?
A form of an element with the same number of protons but a different number of neutrons is called this.
What is an isotope?
A base is a substance that produces this in aqueous solution.
What are negative hydroxide ions?
This kind of reaction turns cold.
What is an endothermic reaction?
Increasing the concentration causes a reaction to happen (faster/slower)
What is faster?
This is the energy of the motion of ALL the particles in a substance.
What is thermal energy?
What is an alpha particle?
pH 12
This type of reaction has the following general equation:
Reactants + Energy --> Products
What is an endothermic reaction?
Lowering the temperature of a reaction will cause it to happen (faster/slower)
What is slower?
This material transfers thermal energy and electricity very well.
What is a conductor?
This type of particle is an electron that is not orbiting a nucleus.
What is a beta particle?
What is 0-7?
This type of reaction has the following general equation:
Reactants --> Products + Energy
What is an exothermic reaction
This is the energy required to start a reaction.
What is activation energy?
This material transfers thermal energy and electricity very poorly.
What is an insulator?
Beta particles are released by this subatomic particle, and it turns into this.
What is a neutron, and what is a proton?
A neutralization reaction forms these two substances.
What is water and salt?
Name the two types of energy that change in an endo and exothermic reaction
What are chemical and thermal energy?
A catalyst, such as an enzyme, causes a reaction to happen more quickly by doing this.
What is lower the activation energy?
Which of the following contains more thermal energy: a boiling kettle or a large iceberg?
What is an iceberg?
What are 7 protons and 7 neutrons? (fun fact: this is nitrogen)
