Answer:

The answer to your question is below

Explanation:

Alpha decay occurs when a radioactive atm emits an alpha particle (Helium atom).

a)      ²⁵⁶Ra      ⇒      ²⁵²₈₄ Po  +   ⁴₂He

b)     ²¹⁹Rn       ⇒      ²¹⁵₈₂Pb    +   ⁴₂He

c)      ²¹¹Po      ⇒      ²⁰⁷₈₀Hg    +   ⁴₂Hg

d)      ²¹⁰Pb     ⇒     ²⁰⁶₇₈Pt      +   ⁴₂Hg

e)      ²³⁸U      ⇒     ²³⁴₈₈U       +   ⁴₂Hg

A microwave can have a frequency of 3.8 X 1010Hz. How much energy does this microwave give off in joules?
Marina86 [1]

Answer:

2.52 x 10^{-23} J

Explanation:

The energy given off by the microwave can be determined by the application of Planck's energy formula:

E = hf

where: E is the required energy, h is Planck's constant (6.626 x 10^{-34}m^{2}Kg/s), and f is the frequency (3.8 x 10^{10} Hz).

So that;

E = 6.626 x 10^{-34} x 3.8 x 10^{10}

  = 2.51788 x 10^{-23}

Therefore, the energy released by the wave is 2.52 x 10^{-23} J.

Describe how to test your unknown salt mixture for the presence of<br>Na3PO4.12H2O.​
klemol [59]

Na3PO4*12H2O + BaCl2*2H2O = Ba3(PO4)2 + NaCl + H2O

add barium chloride to your Na3PO4.12H2O a white precipitate of Ba3(PO4)2 will be formed wrt salt(NaCl) and water(H20) if Na3PO4.12H2O. will be there.
