is the balanced equations for the following nuclear reactions.
<h3>What are balanced equations?</h3>
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products
Uranium-233 is produced by the neutron irradiation of thorium-232. When thorium-232 absorbs a neutron, it becomes thorium-233, which has a half-life of only 22 minutes.
Hence, is the balanced equations for the following nuclear reactions.

From the periodic table:
molar mass of barium = 137.2 grams
molar mass of oxygen = 16 grams
molar mass of hydrogen = 1 gram
molar mass of Ba(OH)2 = 137.2 + 2(16) + 2(1) = 171.2 grams
molar mass of 4H2O = 4 [2(1) + 16] = 72 grams
molar mass of Ba(OH)2.4H2O = 171.2 + 72 = 243.2 grams
Therefore, each 243.2 grams of <span>barium hydroxide tetrahydrate contains 72 grams of water, thus, 92.8 grams will contain:
mass of water in 92.8 grams = (92.8 x 72) / 243.2 = 27.474 grams
Based on this, when </span>a 92.8 gram sample of Ba(OH)2•4H2O (barium hydroxide tetrahydrate) is heated until water is released, 27.474 grams of water will be released.
We can use the ideal gas law equation to solve for the number of moles present
PV = nRT
P - pressure - 107 kPa
V - 39.0 x 10⁻⁶ m³
n - number of moles
R - 8.314 Jmol⁻¹K⁻¹
T - temperature in K - 27 °C + 273 = 300 K
Substituting these values into the equation
107 000 Pa x 39.0 x 10⁻⁶ m³ = n x 8.314 Jmol⁻¹K⁻¹ x 300 K
n = 1.67 x 10⁻³ mol
