Answer:
N₂ is the limiting reactant
Explanation:
The balanced reaction between N₂ gas and H₂ gas is:
N₂ + 3H₂ → 2NH₃
In order to determine the limiting reactant, we have to <u>calculate the number of moles of each rectant</u>, using their molecular weight:
- Moles of N₂= 100 kg *
= 3.57 kmol - Moles of H₂= 100 kg *
= 50.0 kmol
Lastly, we multiply the number of moles of N₂ by 3, and the number of moles of H₂ by 1; due to the coefficients in the balanced reaction. Whichever number is lower, belongs to the limiting reactant.
N₂ => 10.7
H₂ => 50.0
Thus N₂ is the limiting reactant
2.4 × 10⁻² is the pH of a solution
What is the short definition of pH?
- The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
- In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.
Equation representing the i onization of Na₃PO₄ is as fallow
Na₃PO₄ → PO₄³⁻ + 3Na⁺
Concentration of Na₃PO₄ = 
Since 1 mol of Na₃PO₄ forms 1 mol of PO₄³⁻ [ PO₄³⁻ ] = [ Na₃PO₄ ] = 0.164 M
Equation representing the i onization of HPO²⁻₄ is as fallow
HPO²⁻₄ → PO₄³⁻ + H⁺
Acidionization constant Ka₃ of HPO²⁻₄ = 4. 17 × 10⁻¹³
Baseionization constant Kb₃ of PO₄³⁻ = Ka₃/ Kb₃
= 1 .0 × 10⁻¹⁴/ 4. 17 × 10⁻¹³ = 2.4 × 10⁻²

The Ring of fire most seismically and volcanically active zone in the world.
Answer:
All matter contains heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.
