The overall molecule is Polar because the shape of the molecule is Trigonal Pyramidal, which means it has the lone pair electrons. Becuase of the lone pair the pulling is unequal.

H3O+ has 3 polar bonds.
To know if the bonds are polar or nonpolar find the difference of the element's electronegativity charge.
H has electronegativity charge of 2.2, and O has 3.4.
Always subtract the smaller number from the greater one.
So 3.4 - 2.2 = 1.2
If the difference is from 0-0.4 the bond is nonpolar, but if it's from 0.5-1.9 the bond is polar.
So, 1.2 is polar bond. So H3O+ has 3 polar bonds, and the overall molecule is polar too.

A simple way to know if it's polar or nonpolar is to draw the lewis dot structure, and use VSEPR.

Answer from: isabellebisio

Polarity is defined as the attraction of atoms within a compound. The attraction create electronegativity, which defines the polarity of a compound. H $_3 \text O^{+}$ is a polar molecule.

Hydronium or $\text H_3 \text O^{+}$ is a polar molecule. It has trigonal pyramidal shape due to presence of lone pairs. The attraction of lone pairs on the compound makes the difference in electronegativity.

Hydronium ions have 3 polar bonds. The difference in the electronegativity of charge can determine the polarity of bonds, such that:

Electronegativity of H = 2.2Electronegativity of O = 3.4

Subtracting the values,

3.4 - 2.2 = 1.2

The polarity of compound ranges between the electronegativity's difference. The value between 0.5-1.9 is considered as polar compound.

Therefore, hydronium ion is a polar compound.

The answer is 4 i don't know if its right let me see.

Answer from: Quest

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
