A heptahedron is a closed 3-d shape with 7 polygonal faces. There are 34 topologically different convex heptahedra and, since none of these are regular, the term is ambiguous. The faces can have from 3 to 6 sides - that is, the bases can range from a triangle to a hexagon.
Bases are not called alkalis. Alkalis are a specific subset of bases that are soluble in water. All alkalis are bases, but not all bases are alkalis.
Bases have a bitter taste. Bases feel slippery to the touch. Bases turn red litmus paper blue.
Yes, all Brnsted-Lowry bases are also considered Arrhenius bases.
Weak bases partially dissociate in water to produce hydroxide ions. This results in a basic solution with a lower concentration of hydroxide ions compared to strong bases. Examples of weak bases include ammonia (NH3) and organic amines.
A base tastes bitter, feels slippery, and turns red litmus paper blue.

A heptahedron can have 6 to 10 vertices.
A heptahedron has seven faces, like a heptagon has seven sides.
A pentagonal heptahedron is a heptahedron comprising two pentagons which are joined to one another by five quadrilaterals. There is no requirement for the pentagons to be congruent nor for them to be parallel to one another.
A heptahedron has 7 faces, including 6 triangular faces and one hexagonal.
A heptahedron is a seven-faced polyhedron. The number of pairs of parallel faces in a heptahedron can vary depending on its specific shape and configuration. For example, a regular heptahedron, such as a truncated triangular prism, may have pairs of parallel faces, while other irregular heptahedra may not have any. Therefore, the answer is not fixed and can range from zero to multiple pairs based on the specific heptahedron in question.

A heptahedron is a polyhedron with seven faces. The number of vertices in a heptahedron can be determined using Euler's formula, which states that for any polyhedron, the number of vertices (V), edges (E), and faces (F) are related by the equation V - E + F = 2. Since a heptahedron has 7 faces, the equation becomes V - E + 7 = 2. The number of edges in a heptahedron can vary depending on its specific shape, so the number of vertices cannot be determined without additional information about the edges.
