They also believe that the chemical occurred in the ocean
As always, it is my pleasure to help students like you!
Answer:
NO
Explanation:
<u>It would be difficult to plot a line of best fit on the scattered graph of the activities of metal blocks as the activities would almost be the same horizontally on the graph</u> and an attempt to draw/determine an intercept will be almost impossible. The line of best fit is usually drawn to determine the relatedness/correlation of the variables.
Drawing intercept for the activities of the liquid is easier because a line of best fit can be easily placed between the clustered liquid activities on the scattered plot.
Argon has 8 valence electrons. It's atomic number is 18, therefore, in the first shell there are 2, the second has 8 and the third also has eight.
Hello!
the correct setup is shown at bottom of your question
we get
total moles*(1/102.0 g/mol)= total grams Al2O3
hope this helps. any questions please ask. thank you kindly
