Answer:
Explanation:
Hello there!
In this case, since we have a problem about volume-pressure relationship, the idea here is to use the Boyle's law to calculate the final volume as shown below:
Then, we plug in the initial and final pressures and the initial volume to obtain:
Regards!
A digital thermometer has less errors in reading temperatures because it displays the actual reading rather than approximating it in a liquid-based thermometer. Also, digital thermometer are advantageous to use in extreme temperature conditions because they can withstand in these type of conditions.
Answer:
57.1 kilo Joules of heat would be released.
Explanation:
ΔH°=-57.1kJ/mol
Molarity of HCl = 2.00 M
Molarity of NaOH = 1.00 M
According to reaction , 1 M of HCl reacts with 1 M of NaOH. Then 2.00 M of HCl will react with:
of NaOH
But according to question we only have 1.00 M NaOH .So, this means that NaOH is limiting reagent and HCl is an excessive reagent.
Heat evolved will depend upon concentration of NaOH solution :
Heat evolved when 1.00 M of NaOH reacts =
Negative sign means that heat is released during the reaction.
57.1 kilo Joules of heat would be released.
