Are exothermic reactions decomposition reactions or are they synthesis reactions
Synthesis reactions are generally characterized by being
exothermic. Decomposition reactions are usually endothermic.
What do thermal insulators have
Thermal insulators have insulating capabilities. This means that
they do not have any aspect that allows them to conduct thermal
energy.
Solid metals undergo greater thermal expansion than liquids do
Swamp coolers are effective because
the water's latent heat of vaporization is being pulled from the
air, the water pulls heat from the room to undergo a phase
change.
True or false The concentration of an acid or base refers to how completely it dissociates in water
The of an acid and a base is determined by how completely they dissociate in water
The _____________ of an acid and a base is determined by how
completely they dissociate in water.
strength
Sodium hydroxide is a common what
Sodium hydroxide, also known as lye or NaOH, is a common base.
NaOH is a strong base, and thus fully dissociates in aqueous
solution.
What amount of acid or base dissolved in water called
Which one of the following is a common acid soap aspirin antacid and washing soda
Which one is an example of an indicator litmus paper electricity high concentration or presence of H- ions in solution
Which of the following is an example of redox reaction-
Redox reaction is chemical reactions. This happens when atoms
oxidation state changes.
Which one of the following is an example of a strong acid
Hydrochloric acid -APEX;)
Changing subscripts is one of the steps of balancing a chemical equation.
A base is a substance that forms hydroxide ions in a water solution.
On a very hot summer day, railroad tracks can buckle, causing train delays and derailments. Select the best reason below for the buckling
The metal undergoes thermal expansion.
