Answer to Question #153868 in General Chemistry for Sabrina Ahmed

Question

Calculate the change in temperature for both trials. Determine the average temperature change.  Construct a graph from the data obtained (curve/line of best fit). Proper graph format should include a title, and labeled axes with units). Please use a graphing program such as excel, google sheets, or Graphmatica.

information given:

Initial temperature: 20 degrees celsius (1 I)  Final temperature: 26.81 degrees celsius

the first solution,Ba(OH)2 . volume-50.0 mL and molarity- 1.000 M.

HCl(aq) volume-50.00 mL and molarity-1.000 M.

Answer 1

Change in temperature for both trails is

$\Delta$ T = 26.81⁰C - 20⁰C

$\Delta$ T = 6.81⁰C

In the above question you have mentioned the same details for both Ba(OH)₂ and HCl

Volume 50.0ml and molarity = 1.000M

So the graph is a line
