Answer:
Delta H per mole =55733.3J
Explanation:
volume of solution = 40ml +40ml =80ml
Mass of solution = 80g (since the density is the same as pure water (1.00 g/mL)
Temperature rise = (27-25)oc =2oc.
Heat liberated (Q) = -McT
= 80* 4.18* 2= -668.8J
Number of moles of NaOH in solution = 0.3x 40/1000 =0.012 mole.
Number of moles of HBr in solution =0.3x 40/1000 =0.012 mole.
When 0.012 mole of NaOH reacts with 0.012 mole of HBr, -668.8J was liberated.
Hence. 1 mole of NaOH reacts with 1mole HBr to liberate. =-668.8/0.012 =55733.3J
Answer:
Ununennium.
Explanation:
Ununennium, also known as <em>eka-francium</em> or <em>element 119</em>, is the hypothetical chemical element with symbol <em>Uue</em> <em>and atomic number 119. </em> It's Mass number is [315] (predicted), as we as it is existing on the periodic table hence its symbol: <em>Uue</em>
