Additional topics include atomic structure, bonding types, and periodic table trends, all aimed at enhancing foundational knowledge in chemistry.
Card 1
What does STP stand for in chemistry?
Standard Temperature and Pressure.
Card 2
What are heat variables for water used for?
Calculating needed energy for heat change.
Card 3
What are measurement prefixes used for?
For very small or large numbers.
Card 4
What do polyatomic ions act like?
They act like singular ions.
Card 5
How is solubility determined for a compound?
By checking if it contains listed ions with exceptions.
Card 6
What does a solubility table show?
Compounds' solubility based on temperature and water quantity.
Card 7
What determines if a liquid becomes a gas?
If pressure and temperature are above the liquid's line, it becomes a gas.
Card 8
What distinguishes endothermic and exothermic reactions?
Negative numbers are exothermic; positive numbers are endothermic.
Card 9
How is hydrogen unique among elements?
Hydrogen is not a metal but behaves like one.
Card 10
What ion is common in acids?
Acids have a hydrogen ion.
Card 11
What ion is common in bases?
Bases have a hydroxide (OH) ion.
Card 12
What do acid-base indicators do?
They change color based on pH range.
