1. Iyada oo ku saleysan isla'egta soo socota ee falgalka isku-dhafka , go'aami tamarta laga soo saaro falgalka isku-dhafka!
Solution
Cufnaanta falgalka iyo badeecada:
Cufka falgalka ( m reactant ) = 1.0078 amu + 1.0078 amu = 2.0156 amu
Cufka badeecada ( m product ) = 2.01410 amu + 0.00055 amu = 2.01465 amu
Lumitaanka cufka falcelinta:
Δm = m falgalayaal - alaabada m
Δm = 2.01560 amu - 2.01465 amu
Δm = 0.00095 amu
Lumitaanka cufka falcelinta waa 0.00095 amu.
1 amu = 931 MeV. 0.00095 amu = 0.00095 x 931 MeV = 0.88445 MeV.
amu = cutub cuf atomi ah
MeV = megaelectron-volt (cutub tamar)
2. Iyada oo ku saleysan isle'egta soo socota ee falgalka isku-dhafka, go'aami tamarta laga soo saaro falgalka isku-dhafka!
Xalka:
Cufnaanta falgalka iyo badeecada:
Cufka falgalka ( m reactant ) = 2.014 amu + 3.016 amu = 5.03 amu
Cufka badeecada ( m badeecad ) = 4.0026 ammo + 1.0084 ammo = 5.011 ammo
Lumitaanka cufka falcelinta:
Δm = m falgalayaal - alaabada m
Δm = 5.03 amu - 5.011 amu
Δm = 0.019 amu
Lumitaanka cufka falcelinta waa 0.019 am.
1 amu = 931 MeV. 0.019 amu = 0.019 x 931 MeV = 17.689 MeV = 17.69 MeV.
3. Iyada oo ku saleysan isle'egta soo socota ee falgalka isku-dhafka, go'aami tamarta laga soo saaro falgalka isku-dhafka!
Xalka:
Cufnaanta falgalka iyo badeecada:
Cufka falgalka ( m reactant ) = 13.0033 amu + 2.0141 amu = 15.0174 amu
Cufka badeecada (m product ) = 14.0030 amu + 1.0078 amu = 15.0108 amu
Lumitaanka cufka falcelinta:
Δm = m falgalayaal - alaabada m
Δm = 15.0174 amu - 15.0108 amu
Δm = 0.0066 amu
Lumitaanka cufka falcelinta waa 0.0066 am.
1 amu = 931 MeV. 0.0066 amu = 0.0066 x 931 MeV = 6.1446 MeV.
4. Iyada oo ku saleysan isle'egta soo socota ee falgalka isku-dhafka, go'aami tamarta laga soo saaro falgalka isku-dhafka.
Xalka:
Cufnaanta falgalka iyo badeecada:
Cufka falgalka ( m reactant ) = 4 ( 1.0078 amu ) = 4.0312 amu
Cufka badeecada ( m product ) = 4.0026 amu + 0.0005 amu = 4.0031 amu
Lumitaanka cufka falcelinta:
Δm = m falgalayaal - alaabada m
Δm = 4.0312 amu - 4.0031 amu
Δm = 0.0281 amu
Lumitaanka cufka falcelinta waa 0.0281 amu.
1 amu = 931 MeV. 0.0281 amu = 0.0281 x 931 MeV = 26.1611 MeV.
