How many moles of neon occupy a volume of 14.3 l at stp? how many moles of neon occupy a volume of 14.3 l at stp? 1.57 moles 0.6
andriy [413]
The  number   of  neon  moles  that  occupy  a volume of 14.3 l  at STP is calculated as follows

At STP 1  mole = 22.4 liters

what about  14.3 liters

by cross  multiplication
= (1 mole x 14.3 l)/22.4 l =0.638  moles  of  neon

Compare a crystal lattice with a molecule. What does the formula unit Al(OH)3 tell you about the compound aluminum hydroxide?
olasank [31]
Molecules are made up by chemically bonding two or more atoms of the same element or different elements, they don’t have charge, and the atoms are bonded by covalent bonds. <span>Lattices have a three- dimensional ordered arrangement of basic units (that can be an atom, molecule or an ion). Lattices are crystalline structures with these repeated basic units. When ions joined with ionic bonds, they form ionic crystals. The formula unit tells us that aluminium hydroxide has a crystal structure made from molecules. </span>

snow_lady [41]

Explanation:

Matter can be categorized into substances and mixtures.

Matter is anything that has mass and occupies spaces.

Substances are distinct matter with the following properties:

  • All parts are the same throughout i.e homogeneous
  • Their composition is definite
  • They cannot be easily separated or broken down into simpler substances by physical means
  • Separation by physical means is not easy
  • They have a unique set of physical properties.

Mixtures have the following properties:

  • Their composition is indefinite i.e they consist of two or more elements and/or compounds in any proportion by mass
  • Their constituents retains their identity
  • They can easily be separated by physical means
  • They have a broad range of physical properties.

Incomplete precipitation of barium sulfate

Explanation:

The student has precipitated and digested the barium sulfate on his/her side. But on the addition of BaCl_2 in the solution, the solution become cloudy. This happened because incomplete precipitation of barium sulfate by the student. When BaCl_2 is added, there are still sulfate ions present in the solution with combines with BaCl_2 and forms BaSO_4 and the formation of this precipitate makes the solution cloudy.
