Answer:
1.31 X 10^ -10 joules per Fe 56 atom
Explanation:
The mass of a proton is 1.673 × 10-24 g. The mass of a neutron is 1.675 × 10-24 g. The mass of the nucleus of an 56Fe atom is 9.289 × 10-23 g. What is the nuclear binding energy (in J) for 56Fe? (c = 3.00 × 108 m/s)
some of the theoretical mass will be converted to binding energy
by Einstein's famous relativity equation
E = mc^2
where E is in joules, m is in Kgm. c is in m/sec
56Fe is element 26 so it has 26 protons and 56 -26 =30 neutrons
its theoretical nuclear mass is
(26 X 1.673 X 10^-24) + (30X1.675 X 10^-24) =
(43.498 X 10^-24) + (50.250 X 10^-24)=
93.748 X 10^24 gm
but its actual mass is 9.289 X 10^-23 g or
92.289 X 10^-24 g
the mas defect is the theoretical mass minus the actual
1.459 X 10^-24 gm =^
1.459 X 10^-27 Kgm
c = 3.00 X 10* m/s=
so joules of binding energy = (1.459 X 10^-27) X 9 X10^16)
1.31 X 10^ -10 joules per Fe 56 atom
Answer:
C₄H₁₀(g) + O₂(g) ⇒ CO₂(g) + H₂O(g)
2 C₄H₁₀(g) + 13 O₂(g) ⇒ 8 CO₂(g) + 10 H₂O(g)
Explanation:
Butane gas (C₄H₁₀) burns in oxygen gas to produce carbon dioxide gas and water vapor. The unbalanced equation is:
C₄H₁₀(g) + O₂(g) ⇒ CO₂(g) + H₂O(g)
First, we will balance carbon and hydrogen which are in just one compound on each side.
C₄H₁₀(g) + O₂(g) ⇒ 4 CO₂(g) + 5 H₂O(g)
Finally, we will balance the oxygen atoms.
C₄H₁₀(g) + 6.5 O₂(g) ⇒ 4 CO₂(g) + 5 H₂O(g)
In order to have integers, we will multiply everý compound by 2.
2 C₄H₁₀(g) + 13 O₂(g) ⇒ 8 CO₂(g) + 10 H₂O(g)
Answer: Anaphase—easy way to remember is thinking anaphase=apart
Explanation:
V=0 m/s, u=?, a = 9.8 m/s² and s = 0.8 m
u²=2×9.8×0.8=15.68
<span>u=3.959 ≈ 3.96 m/s
