Determine the identity of the daughter nuclide from the positron emission of 6832ge. determine the identity of the daughter nucl

RideAnS [48]

Answer:- The daughter nuclide is Gallium with atomic number 31 and mass number 68.

Explanations:- Positron emission is also known as beta plus decay. In this type of radioactive decay in which a proton changes into neutron and a positron and electron neutrino are released.

As the proton changes into neutron, mass number remains same but the atomic number decreases by one unit.

The given element is Ge with atomic number 32 and mass number 68. Mass number decreases by one unit means the atomic number of the daughter nuclide would be 31 and it is Gallium.

The equation could be written as:

$_3_2Ge^6^8\rightarrow _3_1Ga^6^8+e^++v_e$

Predict the precipitate that will be formed in the following reaction:<br> NaF(aq) + AgNO3(aq) →

netineya [11]

The precipitate that will be formed : AgF

<h3>Further explanation</h3>

One indication of the double displacement reaction is the precipitation reaction

Solubility Rules:

• 1. soluble compound

All compounds of Li +, Na +, K +, Rb +, Cs +, and NH4 +

All compounds of NO₃⁻ and C₂H₃O₂⁻

Compounds of Cl−, Br−, I− except Ag⁺, Hg₂²⁺, Pb²⁺

Compounds of SO₄²⁻ except for Hg₂²⁺, Pb²⁺, Sr²⁺, Ba²⁺

• 2. insoluble compounds

Compounds of CO₃²⁻ and PO₄³⁻ except for Compounds of Li +, Na +, K +, Rb +, Cs +, and NH₄ +

Compounds of OH− except Compounds of Li +, Na +, K +, Rb +, Cs +, NH₄⁺, Sr²⁺, and Ba²⁺

Reaction

NaF(aq) + AgNO₃(aq) →NaNO₃(aq)+ AgF(s)

From the solubility rules above, it has been shown that the salts of the Ag⁺ cations are insoluble salts
