Which isotope completes this nuclear reaction?

Chemistry
1 answer:
deff fn [24]2 years ago
5 0

Answer:

¹³₆C

Explanation:

The given nuclear reaction is:

          ¹⁰₅B + ₂⁴He → ᵃₙX + ₁¹H

In balancing nuclear reaction equation, the mass number which are the superscript and atomic number, the subscript on both sides of the equation must be the same.

For the mass number:

                  10 + 4 = a + 1

                  14 = a + 1

                    a = 13

For the atomic number:

             5 + 2 = n + 1

                7 = n + 1

                  n = 6

Note: n is the same as z from the equation

        therefore our atom is ¹³₆X which is an isotope of carbon, ¹³₆C

An exhaled air bubble underwater at 290.
Vinil7 [7]

The answer for the following problem is mentioned below.

  • <u><em>Therefore the final volume of the gas is 52.7 ml.</em></u>

Explanation:

Given:

Initial pressure (P_{1}) = 290 kPa

Final pressure (P_{2}) = 104 kPa

Initial volume (V_{1}) = 18.9 ml

To find:

Final volume (V_{2})

We know;

From the ideal gas equation;

    P × V = n × R × T

where;

P represents the pressure of the gas

V represents the volume of gas

n represents the no of the moles

R represents the universal gas constant

T represents the temperature of the gas

So;

   P × V = constant

   P ∝ \frac{1}{V}

From the above equation;

              \frac{P_{1} }{P_{2} }  = \frac{V_{2} }{V_{1} }

P_{1} represents the initial pressure of the gas

P_{2} represents the final pressure of the gas

V_{1} represents the initial volume of the gas

V_{2} represents the final volume of the gas

Substituting the values of the above equation;

                    \frac{290}{104} = \frac{V_{2} }{18.9}

             V_{2} = 52.7 ml

<u><em>Therefore the final volume of the gas is 52.7 ml.</em></u>
