6.349 g mass of anhydrous magnesium sulfate will remain.
<h3>What are moles?</h3>A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Molar mass MgSO₄.7 H₂O = 246.52 g/mol
0.0527 moles
Molar mass MgSO₄ = 120.4 g/mol
Mass of anhydrous magnesium sulfate :
( 0.0527 x 120.4 ) => 6.349 g

<u>Answer:</u>
<u>For A:</u> The equation is
<u>For B:</u> The equation is
<u>For C:</u> The equation is
<u>Explanation:</u>
Alpha decay process is the process in which nucleus of an atom disintegrates into two particles. The first one which is the alpha particle consists of two protons and two neutrons. This is also known as helium nucleus. The second particle is the daughter nuclei which is the original nucleus minus the alpha particle released.
Beta decay process is defined as the process the neutrons get converted into an electron and a proton. The released electron is known as the beta particle. In this process, the atomic number of the daughter nuclei gets increased by a factor of 1 but the mass number remains the same.
<u>For A:</u> Uranium-238 emits an alpha particle
The nuclear equation for this process follows:
<u>For B:</u> Plutonium-239 emits an alpha particle
The nuclear equation for this process follows:
<u>For C:</u> Thorium-239 emits a beta particle
The nuclear equation for this process follows:
