CHEM.9.A

Previous Next
The student is expected to interpret, write, and balance chemical equations, including synthesis, decomposition, single replacement, double replacement, and combustion reaction using the law of conservation of mass;

A student expectation is directly related to the knowledge and skills statement, is more specific about how students demonstrate their learning, and always begins with a verb. Student expectations are further broken down into their component parts, often referred to as “breakouts.”

  • Overview
  • Alignments
Side-by-Side 

CHEM.9.A — Vertical Alignment

Vertical alignment shows student expectations in the same subject area at different grade levels that are related to or build upon one another.

S.8.6.E
investigate how mass is conserved in chemical reactions and relate conservation of mass to the rearrangement of atoms using chemical equations, including photosynthesis.
IPC.8.B
develop and use models to balance chemical equations and support the claim that atoms, and therefore mass, are conserved during a chemical reaction;
CHEM.9.A
interpret, write, and balance chemical equations, including synthesis, decomposition, single replacement, double replacement, and combustion reactions using the law of conservation of mass;

CHEM.9.A — Breakout of skills

Breakouts are the component parts that make up a student expectation. A breakout shows a distinct concept a student should know or a distinct skill that a student should be able to demonstrate.

The student is expected to
balance chemical equations including
combustion reactions using the law of conservation of mass
decomposition reactions using the law of conservation of mass
double replacement reactions using the law of conservation of mass
single replacement reactions using the law of conservation of mass
synthesis reactions using the law of conservation of mass
interpret chemical equations including
combustion reactions using the law of conservation of mass
decomposition reactions using the law of conservation of mass
double replacement reactions using the law of conservation of mass
single replacement reactions using the law of conservation of mass
synthesis reactions using the law of conservation of mass
write chemical equations including
combustion reactions using the law of conservation of mass
decomposition reactions using the law of conservation of mass
double replacement reactions using the law of conservation of mass
single replacement reactions using the law of conservation of mass
synthesis reactions using the law of conservation of mass
