Answer:
2. Write balanced nuclear equations for the following situations. For each, be sure to show the parent element, the daughter element, and any particles emitted. For each element, use notation that includes atomic mass and atomic number. (12 points)
a. Actinium-225 decays by alpha decay. (3 points)
225 - 4 = 221, 89 - 2 = 87,
" 225/89 Ac = 221/87 Fr + 4/2 a "
b. Helium-6 decays by beta decay. (3 points)
neutron= 4-1=3 proton= 2+1=3
" 6/2 He = 6/3 Li + 0/-1 β "
c. Barium-141 and krypton-92 are produced by the bombardment of uranium-235 with a neutron. Complete the reaction:(3 points)
235/92 Ur + 1/0 n = 141/56 Ba + 92/36 Kr ?
d. Deuterium and tritium fuse to form helium-4. (3 points)
2/1 H + 3/1H = 4/2 He + 1/0 n
Explanation:
a p e x, and btw the deuterium and tritium are isotopes of hydrogen, your welcome :)
Answer:
V₂ = 290.3 cm³
Explanation:
Given data:
Initial pressure = 882 KPa
Initial volume = 312 cm³
Final pressure = 948 KPa
Final volume = ?
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
882 KPa× 312 cm³ = 948 KPa × V₂
V₂ = 882 KPa× 312 cm³/ 948 KPa
V₂ = 290.3 cm³

Answer:
The symbol for an atom can be written to show its mass number at the top, and its atomic number at the bottom. To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.
