Answer: kJ
Explanation:
The thermochemical equation for decomposition of ammonium nitrate is:
Given mass= 50.0 kg = (1kg=1000g)
According to stoichiometry:
1 mole of gives = 82.1 kJ of heat
Thus of
give =
kJ of heat
Thus kJ of heat is evolved from the decomposition of 50.0 kg of ammonium nitrate.
The addition of hydrogen carbonate to bromothymol blue turns the solution blue. Thus, option B is correct.
The balanced equation for the dissociation of bromothymol blue is:
The color of dissociated form is yellow and undissociated form is blue.
<h3>What is the final color of solution?</h3>The addition of hydrogen carbonate results in the dissociated ions as:
The dissociation results in the increased hydrogen ion concentration. The undissociated form in the reaction mixture increases.
Thus, the color of the solution will turn blue. Hence, option B is correct.
