The statements which best describe beta decay are: option 1, 2 and 4.
<h3>What is a beta particle?</h3>
A beta particle can be defined as an isotope which typically undergoes radioactive decay through the emission of a radiation with a -1 charge.
Based on scientific information and records from radioactivity, we can infer that the statements which best describe beta decay are:
- During beta decay, an atom of proton becomes a neutron and a positron.
- During beta decay, an atom of neutron becomes a proton and an electron.
- Beta decay releases energy.

#SPJ4
Answer:
0.09425
Explanation:
The reactant is in solid phase and therefore has zero partial pressure.
The products have the same mole ratio (1:1) and will have the same partial pressure = 1/2 × 0.614 atm = 0.307 atm
Kp = (NH3)(H2S) = 0.09425

Answer:
0.18 moles
Explanation:
Applying,
PV = nRT................... Equation 1
Where P = pressure, V = volume, n = number of moles, R = molar gas constant, T = temperature.
make n the subject of the equation
n = PV/RT............... Equation 2
Given: V = 5.3 L, T = 22 °C = (22+272) K = 295 K, P = 632 mmHg = (0.00131579×632) = 0.8316 atm, R = 0.083 L.atm/K.mol
Substitute these values into equation 2
n = (0.8316×5.3)/(0.083×295)
n = 0.18 moles
, we need to supply it
