Answer:

With some chemical knowledge, you can fairly easily guess if a molecule will be polar or not. Each atom will have a different level of electronegativity, or ability to attract electrons. Actually calculating the polarity of a molecule precisely, however, requires determining the shape of the molecule and performing vector addition. The length of each vector will correspond to the electronegativity of the atom in each bond. The direction of the vector will correspond to molecular shape.

   Draw the molecule in standard chemical format, with all atoms and free electrons shown in the drawing.

   Determine the shape of the molecule. With one or two bonded atoms, the molecule will be linear. With two bonded atoms and unbonded electrons, the molecule will be angular. With three bonded atoms and no free electrons, the molecule will be flat triangular. With three bonded atoms and a set of free electrons, the molecule will be triangular, pyramidal. With four bonded atoms, the molecule will be pyramidal.

How to Know If a Compound Is Polar or Non-Polar?

With some chemical knowledge, you can fairly easily guess if a molecule will be polar or not. Each atom will have a different level of electronegativity, or ability to attract electrons. Actually calculating the polarity of a molecule precisely, however, requires determining the shape of the molecule and performing vector addition. The length of each vector will correspond to the electronegativity of the atom in each bond. The direction of the vector will correspond to molecular shape.

   Draw the molecule in standard chemical format, with all atoms and free electrons shown in the drawing.

   Determine the shape of the molecule. With one or two bonded atoms, the molecule will be linear. With two bonded atoms and unbonded electrons, the molecule will be angular. With three bonded atoms and no free electrons, the molecule will be flat triangular. With three bonded atoms and a set of free electrons, the molecule will be triangular, pyramidal. With four bonded atoms, the molecule will be pyramidal.

   

Determine the electronegativity of each atom in the molecule. Use a standard measurement, such as a centimeter per whole unit of electronegativity, to determine the length of each vector.

Draw a vector of the appropriate length for each atom that you determined vector length. Draw them facing the direction they would face in the molecule, according to the shape determined in Step 2.

Line up the vectors end to end. The distance between your starting point and the final vector is the measurement of polarity in the molecule. For example, if you used 1 cm per whole unit of electronegativity, and your final distance between the last vector and your starting point is 5 mm, the molecule has a polarity of 0.5 in that direction.

What is chemical and physical properties?<br> !
Scilla [17]

Answer:

Physical property: Any characteristic that can be determined without changing the substance's chemical identity. Chemical property: Any characteristic that can be determined only by changing a substance's molecular structure.

Explanation:

Physical properties are something that is reverseable or has no change visible. Chemical properties are something that is NOT reverseable.

Chemical: Gas forming or Color Changing. (ETC.)

what is the number of each type of atom on the right side of the equation 2Na3PO4(aq)+2CoCl2(aq)→2Co3(PO4)2(s)+6NaCl(aq)
Andre45 [30]

6 atoms of Cobalt.

4 atoms to Phosphate (PO4).

6 atoms to sodium.

6 atoms to Chlorine.

The coefficient is one factor that tells you how many atoms go to each atom/element, however, the subscript also influences this.

If the compound has parenthesis, then the subscript within the parenthesis remains untouched and does not affect the atoms.

Basically, to calculate the atoms is multiply the coefficient (number in front of the atom) by the subscript attached to the atom. If it's a compound such as Co3PO4, then make sure the coefficient affects the second atom as well.

Hope this helps!

Name the following aromatic hydrocarbon:
Tresset [83]

3-Methylpentane is the IUPAC name for the substance.

whether in a continuous chain or a ring, the longest chain of carbons joined by a single bond serves as the basis for IUPAC nomenclature. According to a precise set of priorities, all deviations—whether they involve numerous bonds or atoms other than carbon and hydrogen—are denoted by prefixes or suffixes.

+3-Methylpentane is the IUPAC name for the substance in question. It has a lengthy chain of 5 carbon atoms, which gives it the prefix pent-, and a single bond is what gives it the postfix -ane (alkane). Given that the methyl group is present at the third carbon, it is 3-methylpentane.
