According to <em>Prosen and Rossini, 1945</em>,
the standard heat of combustion of isooctane is -5461.3 kJ/mol. The negative sign is just to depict that there was a release of energy. Thus, to
produce 100 kJ energy,
100 kJ ÷ 5461.3 kJ/mol isooctane = 0.0183 moles isooctane.
0.0183 moles of isooctane must be burned.
I hope I was able to answer your question <span>J</span>
MgBr2 is the chemical formula for magnesium bromide
Answer:
Approximately 22.37 days, will it take for the water to be safe to drink.
Explanation:
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration
k is rate constant
Given that:- k = 0.27 (day)⁻¹
= 0.63 mg/L
mg/L
Applying in the above equation as:-
<u>Approximately 22.37 days, will it take for the water to be safe to drink.</u>
I believe the correct answer from the choices listed above is the first option. There are about 840 candies present on all vans present. We calculate it by multiplying the number of total passengers by the number of candies each passenger is carrying. Hope this answers the question.
Explanation:
There are 6.022x1023 molecules in 1 mole of SO3 (Avogadro's number) so in 0.25 moles, there are (0.25)(6.022x1023) molecules in the 0.25 moles of SO3. or 1.506x1023 molecules per 0.25 moles of SO3.
There is one atom of sulfur in each molecule of SO3. So there are 1.506x1023 atoms of sulfur in 0.25 moles of SO3.
