Answer:

This question is incomplete

Explanation:

Experimentally, when trying to determine the concentration of an unknown sample of CuSO₄ with known absorbance, a standard curve is used. The standard curve is a scattered plot/graph in which known concentrations and there respective/corresponding absorbance are plotted on a "X and Y axis" graph (scattered plot). The absorbance is represented on the y-axis while the concentration is represented on the x-axis.

Once this known values are plotted on the standard curve, an unknown value (either absorbance or concentration) can be extrapolated from the curve. What is missing from the question is data required for the standard curve.

This question shows the absorbance of the CuSO₄ has been determined (most likely using spectrophotometer), the concentration could have been extrapolated from a standard curve.

An example of a standard curve is provided in the attachment for guidance.

OLEGan [10]

<u>Answer</u>: Large collection of stars, gas, and dust held together by gravity.

<u>Explanation:</u>

  • In simple words a galaxy is a collection of a large number of stars, however, to be more precise <em>a galaxy is a gravity-bound collection of stars, dust, gas, dark matter and stellar remnants. </em>
  • There are different types of galaxies found in various shapes and size, some of the most common shapes being elliptical, irregular and spiral.
  • An example is the milky way galaxy that contains our solar system.
