The question is incomplete, the complete question is;

A chemist prepares a solution of silver (I) perchlorate (AgCIO4) by measuring out 134.g of silver (I) perchlorate into a 50.ml volumetric flask and filling the flask to the mark with water. calculate the concentration in mol/L of the silver (I) perchlorate solution. Round your answer to 2 significant digits.

Answer:

13 mol/L

Explanation:

We must first obtain the number of moles of silver I perchlorate involved

Molar mass of silver I perchlorate = 207.32 g/mol

Number of moles of silver I perchlorate = 134g/207.32 g/mol = 0.646 moles

Recall that;

n =CV

C= concentration

V= volume

n = number of moles

C = n/V

C = 0.646 moles * 1000/50

C = 13 mol/L

Suspensions

Explanation:

Suspensions are heterogeneous mixtures that contains large particles that can settle out or be filtered.

  • Suspensions are mixtures of small insoluble particles of a solid in a liquid or gas.
  • Examples are:
  1.  powdered chalk in water
  2. muddy water
  3. harmattan

The particles in suspension can settle on standing

What is the molecular geometry around each carbon atom in a saturated hydrocarbon?
Lelu [443]
Answer:
            <span>Molecular geometry around each carbon atom in a saturated hydrocarbon is Tetrahedral.

Explanation:
                     </span> In saturated hydrocarbons (-CH₂-) the central atom (carbon) is bonded to either three or two hydrogen atoms and one or two carbon atoms. So, the central atom is having four electron pairs and all pairs are bonding pairs and lacks any lone pair of electron. According to Valence Shell Electron Pair Repulsion (VSEPR) Theory the central atom with four bonding pair electrons and zero lone pair electrons will attain a tetrahedral geometry with bond angles of 109°.
