State whether the following liquids are miscible with hexane (C6H14) by entering "yes" or "no".
NeTakaya

Benzene, C6H6 is miscible with hexane (C6H14)  but iron (IIl) nitrate, and Sulfuric acid, H2SO4Fe(NO3)3 are not miscible with hexane (C6H14)

Since organic or non polar dissolves in nom polar solvent.here both benzene and hexane (C6H14) are non polar solvents.But iron (IIl) nitrate, Fe(NO3)3 and Sulfuric acid, H2SO4 are inorganic and polar, therefore cannot dissolve with non polar solvent like hexane.

Miscible is a flowery heard that oil and water aren't very miscible substances, while seltzer and orange juice are miscible and scrumptious.Miscible beverages are also described as liquids that can blend to form a homogeneous solution. Miscible drinks generally blend with out limit, meaning they may be soluble at all quantities.

Miscible approach the materials blend completely. If  substances are miscible, they're also absolutely soluble in each other no matter the order of creation. for example, tetrahydrofuran and water are miscible.

What occurs along a convergent plate boundary ?
Margaret [11]

Answer:

Two plates pull towards each other

Explanation:

Along a convergent plate boundary, two plates moves towards each other as the move in the same direction.

This results in different forms of plate interactions depending on the plate types.

  • At an ocean - ocean and continental - ocean convergent front, subduction of the oceanic plate occurs. This is because the oceanic plate below is denser than the asthenosphere.
  • At a continental - continental convergent front, the continental crust is pulls upward and build up as a mountain.
  • The subduction produces trenches and some volcanic islands.

The periodic table is useful because it is organized to show many patterns and trends. What property shows a decrease moving fro
Alex73 [517]

Atomic radius

Explanation:

A decrease in moving from the bottom of Group 3 to the top of the group shows an increase in trend from top to bottom.

The atomic radius of elements increases from top to bottom and decreases from the bottom to the top.

The elements in group 3 are B, Al , Ga, In and Tl

  • Atomic radius is taken as half of the inter-nuclear distance between two covalently bonded atoms of non-metallic elements or half of the distance between two nuclei in the solid state of metals.
  • Downs a group from top to bottom, atomic radii increases progressively due to successive shells being added.
  • This compensates for the size reducing effect of the increased nuclear charge.
