6 13.A new home had a wooden floor put down in cool weather. As the weather became
warmer, the floor started to buckle, rising up in the middle of the floor. The floor was
fixed by trimming the edges of the floor so that there was a space between the flooring
and the wall. Choose the response that best explains why this helped to make the floor
flat again.
A. The particles in the floor decrease in thermal energy in warm weather, decreasing
the kinetic energy of its particles and making it expand. Trimming it gave it room to
expand
B. The particles in the floor increase in thermal energy in warm weather, increasing the
kinetic energy of its particles and making it expand. Trimming it gave it room to
expand.
C. The particles in the floor decrease in thermal energy in warm weather, decreasing
the kinetic energy of its particles and making it contract. Trimming it gave it room to
contract.
D. The particles in the floor increase in thermal energy in warm weather, increasing the
kinetic energy of its particles and making it contract. Trimming it gave it room to
contract.

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
