Consider the word equation. Calcium hydroxide hydrochloric acid mc012-1. Jpg calcium chloride water Which is the corresponding f
dimulka [17.4K]

The corresponding formula equation is:

Upper Ca (upper OH) subscript 2 (s) plus 2 upper H upper Cl (l) right arrow upper Ca upper Cl subscript 2 (aq) plus 2 upper H subscript 2 upper O (l)

To obtain the word equation, we shall write out the balanced molecular equation. This is given below:

Calcium hydroxide => Ca(OH)₂

Hydrochloric => HCl

Calcium chloride => CaCl₂

Water => H₂O

Calcium hydroxide + Hydrochloric —> Calcium chloride + water

Ca(OH)₂ + HCl —> CaCl₂ + H₂O

There are 2 atoms of Cl on the right side and 1 atom on the left. It can be balance by writing 2 before HCl as shown below:

Ca(OH)₂ + 2HCl —> CaCl₂ + H₂O

There are a total of 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:

Ca(OH)₂ + 2HCl —> CaCl₂ + 2H₂O

Now, the equation is balanced.

Thus, the corresponding word equation is:

Upper Ca (upper OH) subscript 2 (s) plus 2 upper H upper Cl (l) right arrow upper Ca upper Cl subscript 2 (aq) plus 2 upper H subscript 2 upper O (l)

How does a trigonal pyramid differ from a tetrahedron so far as molecular geometry is concerned? Bond angles in the tetrahedral
Lunna [17]

Answer:

A trigonal pyramid is a tetrahedron with one vacant vertex.

Explanation:

<em>How does a trigonal pyramid differ from a tetrahedron so far as molecular geometry is concerned? </em>

<em>Bond angles in the tetrahedral molecule are 120°, while those for trigonal pyramid are 109.5°.</em>  FALSE. Bond angles in the tetrahedral are 109.5°, while those for the trigonal pyramid are slightly lower than 109.5° due to the repulsion of the unshared pair of electrons on the central atom.

<em>A trigonal pyramid is a tetrahedron with two vacant vertex.</em> FALSE.

<em>A trigonal pyramid is a tetrahedron with one vacant vertex.</em> TRUE. This is the geometry of NH₃, in which the central atom is bonded to 3 atoms and has 1 unshared pair of electrons.

<em>Bond angles in the tetrahedral molecule are 109.5°, while those for trigonal pyramid are 120°.</em> FALSE.

<em>A tetrahedron has a square base, while the base of a trigonal pyramid is a triangle.</em> FALSE. Both have a triangular base.
