<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:
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.
Answer:
The new pressure is 1.70L
Explanation:
Because its going down by 0.5
Answer:
Electron pair geometry - tetrahedral
molecular geometry- trigonal pyramidal
Explanation:
According to Valence Shell Electron Pair Repulsion Theory, the shape of a molecule is determined by the number of electron pairs around the central atom in the molecule. Lone pairs distort a molecule away from its expected geometry based on VSEPR. This is why the electron pair geometry differs from the actual molecular geometry.
PCl3 has four regions of electron density, three substituents and one lone pair hence its electron pair geometry is tetrahedral. However, the three substituents are arranged in a trigonal pyramidal geometry(its molecular geometry).
