Radioactive decay or disintegration is a process through which unstable nuclei form q more stable nuclei by the release of elementary particles like alpha particles, beta, protons, neutrons etc along with the release of energy.
In the given examples:
a) N-13 will get converted in to carbon, C-12 along with the release of a proton as shown below:
₇N¹³ → ₆C¹² + ₁H¹
b) N-15 will get converted in to boron B-11 along with the release of an alpha particle
₇N¹⁵ → ₅B¹¹ + ₂He⁴
False; Because when 2 substances are mixed another substance is created.
C. Unbalanced describes the forces acting on the car
Answer:
15.98 L
Explanation:
First, you need to find T1, T2, V1 and V2.
T1 = 25 C = 298.15 K (25C + 273.15K)
T2 = 100 C = 373.15 K (100C + 273.15K)
V1 = 20. L
V2 = ? (we are trying to find)
Next, rearrange to fit the formula
V2 = V1 x T1 / T2
Next, fill in with our numbers
V2 = 20. L x 298.15 K / 373.15 K
Do the math and you should get...
15.98 L
