Answer:
<h3>The answer is 5.0 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 100 g
volume = 20 mL
So we have
We have the final answer as
<h3>5.0 g/mL</h3>
Hope this helps you
Answer:
0.900 V
Explanation:
Oxidation half cell;
2Al(s) -----> 2Al^3+(aq) + 6e
Reduction half equation;
3Zn^2+(aq) + 6e ----> 3Zn(s)
E°anode = -1.66V
E°cathode= -0.76 V
E°cell= E°cathode - E°anode
E°cell= -0.76-(-1.66)
E°cell= 0.900 V
Answer:
Electrically neutral atoms simply possess the same number of electrons as protons. This gives the objects a balance of both type of charge. There are <u>11 electrons</u> and 10 protons. This results in an imbalance of charge.
