Consider the nuclear equation below. 222/66Rn-->218/?Po+4/2He Which is the missing value that will balance the equation? 84 8
erastovalidia [21]
<h3>Answer:</h3>

84

<h3>Explanation:</h3>
  • The nuclear equation shows the decay of Radon-222 by emitting an alpha particle to form polonium-218.
  • When a radioactive isotope undergoes alpha-decay, the mass number is decreased by 4 while the atomic number decreases by 2.
  • Therefore, the complete nuclear equation is;

²²²₈₆Rn → ²¹⁸₈₄Po + ⁴₂He

  • The atomic number of Radon-222 decreases from 86 to 84 while the mass number decreases from 222 to 218, forming polonium-218.

Consider the following reaction at equilibrium. What effect will decreasing the temperature have on the system? DH=+890kJCO2(g)+
AlladinOne [14]

Answer:

Option B. The reaction will shift to the left in the direction of the reactants.

Explanation:

The equation for the reaction is given below:

CO₂ + 2H₂O <=> CH₄ + O₂

Enthalpy change (ΔH) = +890 KJ

The reaction illustrated by the equation is endothermic reaction since the enthalpy change (ΔH) is positive.

Increasing the temperature of an endothermic reaction will shift the equilibrium position to the right and decrease the temperature will shift the equilibrium position to the left.

Therefore, decreasing the temperature of the system illustrated by the equation above, will shift the reaction to the left in the direction of the reactants.

Thus, option B gives the right answer to the question.
