Question

1. draw a venn diagram comparing physical and chemical properties. on each side of the venn diagram list examples of that property. in the middle, write a sentence that explains how the two are similar to one another.
2. you take a piece of copper metal and place it in a 100ml graduated cylinder that is filled with 45ml of water but raises to 50ml of water. what is the volume of the copper? later you used up the copper in a chemical reaction. however, after doing this, you realize that you forgot to take the mass of the copper. to salvage your experimental data, use your periodic table to identify the density of copper. then use that density and the volume to calculate the estimated mass of copper that you used. circle both answers to the bolded questions.

volume of copper 5ml
mass of copper 44.8g

1. what is one aspect of the reading that you feel expert about. prove with an explanation.

what is one aspect of the reading that you do not feel comfortable with. explain in detail what it is and how you think you can improve on the topic.

Explanation:

Step1: Calculate volume of copper

The volume of the copper is found by the displacement method. The initial volume of water is 45 ml and the final volume is 50 ml. So the volume of copper $V$ is the difference in water - levels.
$V=50 - 45=5$ ml

Step2: Find density of copper

From the periodic - table, the density of copper $
ho = 8.96$ g/ml.

Step3: Calculate mass of copper

We use the density formula $
ho=\frac{m}{V}$, and solve for mass $m$. Rearranging the formula gives $m =
ho\times V$. Substituting $
ho = 8.96$ g/ml and $V = 5$ ml, we get $m=8.96\times5 = 44.8$ g.

Answer:

Volume of copper: 5 ml
Mass of copper: 44.8 g
