Identify the missing species in each nuclear equation. Replace the question marks with the appropriate integer or symbol. Be410⟶
astraxan [27]

Answer:

1.  ¹⁰₄Be ---> ¹⁰₅B + ⁰₋₁β

2. ³⁴₁₄Be ---> ³⁴₁₅P + ⁰₋₁β

3. ¹⁹²₇₈Pt -----> ¹⁹⁰₇₆Os + ⁴₂α

4.  ²⁸₁₂Mg ---> ²⁸₁₃Al + ⁰₋₁β

Explanation:

1. In the first equation, Beryllium-10 isotope undergoes beta-decay, emitting a beta-particle to form boron-10 isotope. The balanced nuclear equation is given below:

¹⁰₄Be ---> ¹⁰₅B + ⁰₋₁β

2. In this reaction, silicon-34 isotope undergoes beta-decay, emitting a beta-particle to form phosphorus-34 isotope. The balanced nuclear equation is given below:

³⁴₁₄Be ---> ³⁴₁₅P + ⁰₋₁β

3. In this equation, platinum-192 isotope undergoes alpha-particle decay emitting an alpha-particle to form osmium-190 isotope. The balanced nuclear equation is given below:

¹⁹²₇₈Pt -----> ¹⁹⁰₇₆Os + ⁴₂α

4. In this equation, magnesium-28 isotope undergoes beta-decay, emitting a beta-particle to form aluminum-28 isotope. The balanced nuclear equation is given below:

²⁸₁₂Mg ---> ²⁸₁₃Al + ⁰₋₁β

This is the net ionic equation for the complete neutralization of a generic diprotic acid with sodium hydroxide: H2A (aq) + 2 Na
kupik [55]

Answer:

c. 2 OH⁻(aq) + 2 H⁺(aq) ⇒ 2 H₂O(l)

Explanation:

Step 1: Write the molecular equation

The molecular equation includes all the molecular species.

H₂A(aq) + 2 NaOH(aq) ⇒ Na₂A(aq) + 2 H₂O(l)

Step 2: Write the complete ionic equation

The complete ionic equation includes all the ions and the molecular species.

2 H⁺(aq) + A²⁻(aq) + 2 Na⁺(aq) + 2 OH⁻(aq) ⇒ 2 Na⁺(aq) + A²⁻(aq) + 2 H₂O(l)

Step 3: Write the net ionic equation

The net ionic equation includes only the ions that participate in the reaction and the molecular species.

2 OH⁻(aq) + 2 H⁺(aq) ⇒ 2 H₂O(l)
