<u>Answer:</u> The balanced molecular equation is written below.
<u>Explanation:</u>
A molecular equation is defined as the chemical equation in which the ionic compounds are written as molecules rather than component ions.
When zinc (II) nitrate reacts with sodium hydroxide, it leads to the formation of white precipitate of zinc (II) hydroxide and an aqueous solution of sodium nitrate.
The balanced chemical equation for the above reaction follows:
![Zn(NO_3)_2(aq.)+2NaOH(aq.)\rightarrow Zn(OH)_2(s)+2NaNO_3(aq.)](https://tex.z-dn.net/?f=Zn%28NO_3%29_2%28aq.%29%2B2NaOH%28aq.%29%5Crightarrow%20Zn%28OH%29_2%28s%29%2B2NaNO_3%28aq.%29)
By Stoichiometry of the reaction:
1 mole of aqueous solution of zinc (II) nitrate reacts with 1 mole of aqueous solution of sodium hydroxide to produce 1 mole of solid zinc hydroxide and 2 moles of aqueous solution of sodium nitrate
Hence, the balanced molecular equation is written above.
S = d/t
S = 78500/10.5
S = 7,476 Knots
Answer:
Barium chloride + Sodium phosphate → barium phosphate + sodium chloride
Explanation:
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
Chemical equation:
BaCl₂ + Na₃PO₄ → Ba₃(PO₄)₂ + NaCl
Balanced chemical equation:
3BaCl₂ + 2Na₃PO₄ → Ba₃(PO₄)₂ + 6NaCl
The cation and anion of both reactants are exchanged with each other.
Ba²⁺ react with PO₄³⁻ and form Ba₃(PO₄)₂ while Cl⁻ react with Na⁺ and form sodium chloride.
Molecular equation:
Barium chloride + Sodium phosphate → barium phosphate + sodium chloride
True!
Because if it has a high pressure, it can skip the liquid phase. The process is called sublimation.
