Answer:
The answer to your question is Aluminum
Explanation:
Number of clues
1.- If this element has 3 rings in its Bohr model, we are looking for and element located in the third period of the periodic table.
For example Sodium, Magnesium, Aluminum, Silicate, Phosphorus, Sulfur, Chlorine and, Argon.
2.- It makes three bonds to become stable, then we are looking for and element located in the third group like
Boron, Aluminum, Gallium, Indium, etc
Conclusion
The element that has both characteristics is Aluminum
Answer:
a.
ZnS(s) + O2(g) → ZnO(s) + SO2(g)
b.
HCl (aq) + Ba(OH)2(aq) → BaCl2(aq) + H2O
The two angles would be both 41 degrees.
x in this case would be 14 degrees.
<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:
The answer is D, reactant.
