Positive ion with a radius smaller than the radius of the atom
Answer:
371km
Explanation:
the lower the more fuel there is
N=m(g)/m.wt
n=85/12(1)+16(2) =1.93 moles
K:
m=155g
M=39g/mol
n = 155g / 39g/mol ≈ 3,97mol
KNO₃:
m=122g
M=101g/mol
n = 122g/101g/mol = 1,21mol
2K + 10KNO₃ ⇒ 6K₂O + N₂
2mol : 10mol
3,97mol : 1,21mol
limiting reagent
KNO₃ is limiting reagent
