In order to model a chemical change in the laboratory, a student wants to select the appropriate measuring apparatus to record t

he reaction. Which apparatus could be used to detect that a chemical change occurred with a substance in a laboratory setting? Select ALL that apply.
A) The student could use a hand lens to see if the original substance had been crushed into smaller particles.
B) The student could perform an odor test to detect if a new smell emerges from the interaction of the substance in the lab.
C) The student could test whether gas was released during the interaction of the substance with another substance in the lab.
D) The student could use a spatula to determine if a precipitate/solid formed at the bottom of the beaker containing the substance. Eliminate E) The student could use a balance and a volumetric flask to determine the mass and volume of the substance in order to determine its density.

elena-s [515]

The large piece of jewelry  that has a mass of 132.6 g and when is submerged in a graduated cylinder that initially contains 48.6 ml water and the volume increases to 61.2 ml once the piece of jewelry is submerged, has a density of: 10.523 g/ml

To solve this problem the formulas and the procedures that we have to use  are:

  • v = v(f)-v(i)
  • d = m/v

Where:

  • d= density
  • m= mass
  • v= volume
  • v(f) = final volume
  • v(i) = initial volume

Information about the problem:

  • m = 132.6 g
  • v(i) = 48.6 ml
  • v(f) = 61.2 ml
  • v = ?
  • d =?

Applying the volume formula we get:

v = v(f)-v(i)

v = 61.2 ml - 48.6 ml

v = 12.6 ml

Applying the density  formula we get:

d = m/v

d = 132.6 g/12.6 ml

d = 10.523 g/ml

<h3>What is density?</h3>

It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.

What type of matter can be physically separated
Aneli [31]

Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components. A chemical substance is composed of one type of atom or molecule
