Answer:
Hey mate, here is your answer. Hope it helps you.
Explanation:
The balanced equation is 2Na+2H2O———-> 2NaOH +H2.
the energy gained by proteins and carbohydrates differs from the energy gained by fats.
proteins and carbohydrates both give 4 kcal per gram
fats give 9 kcal per gram
mass of proteins - 2 g
energy given by proteins - 2 g x 4 kcal/g = 8 cal
mass of carbohydrates - 20 g
energy given by carbohydrates - 20 g x 4 kcal/g = 80 cal
mass of fat - 1 g
energy given by fat - 1 g x 9 kcal/g = 9 cal
total energy = 8 + 80 + 9 = 97 kcal
energy = 97 kcal
That would be either, nuclear power or wind power, depending on what the teacher is looking for...
6.337 X 10^-7. To get this, divide the atoms by Avogadro's number, them multiply my the molar mass of Ni.
