Answer:
3NH₄OH + H₃PO₄ → (NH₄)₃PO₄ + 3H₂O
Products are water and ammonium phosphate
Explanation:
This is a neutralization between a weak base and a weak acid where the products are water and the correspondent salt.
Base: NH₄OH → NH₄⁺ + OH⁻
Acid : H₃PO₄ → 3H⁺ + PO₄⁻³
H⁺ bonds to OH⁻ to make H₂O → As we have 3 protons, we can make 3 moles of water, so there are needed 3 OH⁻.
Phosphate has -3 as oxidation state, then it needs 3 ammonium to form the salt.
The balanced equation is:
3NH₄OH + H₃PO₄ → (NH₄)₃PO₄ + 3H₂O
The conclusion includes a summary of the results, whether or not the hypothesis was supported, the significance of the study, and future research.
4.03 x 10²³ atoms
Explanation:
Given parameters:
Number of moles of FeTiO₃ = 0.67moles
Unknown:
Number of atoms = ?
Solution:
From the compound FeTiO₃ ;
1 mole of FeTiO₃ contains 1 mole of Ti atom
0.67 moles of FeTiO₃ will invariably have 0.67 moles of Ti atoms
A mole of any substance is the quantity of substance that contains the Avogadro's number of particles 6.02 x 10²³ particles
The particles are number of atoms, number of protons, neutrons, electrons, molecules e.t.c
1 mole of Ti = 6.02 x 10²³ atoms of Ti
0.67 moles of Ti = 0.67 x 6.02 x 10²³ = 4.03 x 10²³ atoms

Chemical equilibrium is reach when the concentrations of the product and reactants will no longer change with time. this does not mean that there is no change in concentration, only the net change is zero. the forward rate of reaction is now equal to backward rate of reaction.
