Answer:
Beta decay is most common in elements with a high neutron to proton ratio. Gamma decay follows the form: In gamma emission, neither the atomic number or the mass number is changed. A high energy gamma ray is given off when the parent isotope falls into a lower energy state.

<u>Satelites</u> are a type of space technology utilizes the electromagnetic spectrum to collect information.
Explanation:
Depending on the electromagnetic spectrum that the satellite is designed for, it can be utilized for a certain scientific function. The Hubble Telescope, for example, is designed to perceive the visible light spectrum of electromagnetic radiation to provide the beautiful pictures of space we see today. Some satellites that orbit teh earth are sensitive to infra-red radiation and are used to monitor earth’s atmospheric and ocean temperatures. Some satellites are designed for X-rays and gamma rays and are used to search for supernovae.
<u>Given:</u>
Concentration of NaClO = 0.037 M
ka (HClO) = 4.0*10⁻⁸
<u>To determine:</u>
The pH of the NaClO solution
<u>Explanation:</u>
The hydrolysis of the weak base can be represented by the ICE table shown below-
ClO- + H2O ↔ HClO + OH-
Initial 0.037M 0 0
Change -x +x +x
Equilibrium (0.037-x) x x
kb = kw/ka = [HClO][OH-]/[ClO-]
10⁻¹⁴/4*10⁻⁸ = x²/(0.037-x)
x = [OH-] = 9.62*10⁻⁵
p[OH-] = -log[OH-] = -log [9.62*10⁻⁵] = 4.02
pH = 14-p[OH-] = 14 - 4.02 = 9.98
Ans: pH of the solution is 9.98
