The statement is true. The formation of a solid when two liquids are mixed indicates a reaction because a new substance is formed when the two liquid is mixed and it is evident by the precipitate observed. An example is the reaction of sodium iodide and lead nitrate yielding to lead iodide as the precipitate.
Fisher projection is the representation of organic molecule in2-D without destroying the3-D stereochemical information.
<h3>What does a Fischer projection in organic chemistry mean?</h3>
A Fischer projection is a drawing technique used in organic chemistry to depict molecules in two dimensions while maintaining the three-dimensional stereochemical information regarding the absolute arrangement at chiral centers.
<h3>What sets the Fischer projection apart from the Haworth projection?</h3>
In contrast to Fischer projections, which are used to represent sugars in their open-chain form, Haworth projections are typically employed to represent sugars in their cyclic forms.

Answer:
True
Explanation:
The given statement is true. The elements on the upper right side of periodic table accept the electrons because of higher electronegativity values and form anions.
For example:
Consider the halogens. All halogens accept the one electron per atom to complete the octet and form anion. when they combine with metals metals loses their electrons to halogens atoms and form cations while halogens accept the electrons and form anion.
Consider the sodium chloride salt. The sodium metal loses its one valance electron which is accepted by chlorine.
Na⁺Cl⁻
Magnesium bromide:
To complete the octet bromine required one electron. By gaining the one electron it showed -1 oxidation state.
When bromine combine with magnesium both formed MgBr₂.
The one atom of Mg have +2 oxidation state while bromine have -1 that's why to make the overall compound neutral two bromine atoms combine with one atom of magnesium.
Explanation:
Solids have definite shape and distinct boundaries as such the intermolecular forces between them is maximum
