Lithium iodide has a lattice energy of −7.3×102kJ/mol and a heat of hydration of −793kJ/mol. Find the heat of solution for lithi
Anna007 [38]
Delta H of solution = -Lattice Energy + Hydration 
<span>Delta H of solution=- (-730)+(-793) </span>
<span>Delta H of solution= -63kJ/mol </span>

<span>Now we find moles of LiI: </span>
<span>10gLiI/133.85g=.075moles </span>
<span>multiply moles to the delta H of solution to cross cancel moles. .75moles x -64kJ/mol =4.7</span>

Consider the nuclear equation below. 222/66Rn--&gt;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.

Name one of the new products formed when acids and alkalis mix?
Kruka [31]

Answer:

Water (H20)

Explanation:

When an acid combine with a base, the reaction is called neutralization and it produces salt and water. This can be seen from the reaction between HCl and NaOH as shown below:

HCl + NaOH —> NaCl + H2O

From the above equation, we see clearly that salt (NaCl) and water (H2O) are the new products form.
