What makes H20 a polar molecule? What are the two different poles in the H2O molecule?

Chemistry

sineoko [7]3 years ago

Answer:

The answer to your question is given below

Explanation:

A polar molecule is a molecule in which the electrons that made up the atoms in the covalent bond are not evenly distributed. That is the more electronegative element in the molecule tends to attract more electrons to itself thereby causing unevn distribution of the electrons.

Water is composed of Hydrogen and oxygen and it considered a polar molecule because it has a bent shape which allows the more electronegative element oxygen to attract more electrons to itself, thereby causing an unequal distribution of the electrons that made up the covalent bond hence a partial positive and partial negative pole arise

The two different poles in water molecule are:

1. Partial positive pole.

2. Partial negative pole.

How many moles of \ce{CO2}COX
inn [45]

Answer:

4.5 moles of carbon dioxide

Explanation:

Given parameters:

Mass of CH₄   = 72g

Unknown:

number of moles of CO₂ produced  = ?

Solution:

To solve this problem, let us write the reaction equation first;

            CH₄     +    2O₂     →    CO₂    +   2H₂O

Now we know that O₂ is in excess and CH₄ is the limiting reactant that will determine the extent of the reaction.

Let us find the number of moles of   CH₄ ;

                Number of moles  = \frac{mass}{molar mass}

                                  molar mass of  CH₄ = 12 + 4  = 16g/mol

              Number of moles  = \frac{72}{16}   = 4.5moles

From the reaction equation;

                     1 mole of methane produced 1 mole of carbon dioxide

       4.5 moles of methane will produce 4.5 moles of carbon dioxide

What is the configuration of all electron pairs arranged around oxygen in a water molecule? bent trigonal planar tetrahedral lin
jek_recluse [69]
I think the answer would be : Tetrahedral

Oxygen has 6 electrons and need 2 more electron to complete its octet.  In Tetrahedral, the electrons are arranged so it surround the oxygen and forming a 109 degree bond angel/

What is the mass in grams of KBr in 0.400 L of a 0.350 M solution???
melamori03 [73]

Answer:

The answer to your question is: 16.7 g of KBr

Explanation:

Data

mass KBr = ? g

Volume = 0.400 L

Concentration = 0.350 M

Formula

Molarity = moles / volume

moles = molarity x volume

Process

moles = (0.350)(0.400)

          = 0.14

MW KBr = 39 + 80 = 119 g

                                  119 g of KBr --------------------  1 mol

                                   x                 --------------------   0.14 mol

                                   x = (0.14 x 119) / 1

                                   x = 16.7 g of KBr

Sabendo que os calores de combustão do enxofre monoclínico e do enxofre rômbico são, respectivamente, - 297,2 kJ/mol e - 296,8 k
liq [111]

Responda:

+ 0,9kJ / mol

Explicação:

Dados os calores de combustão do enxofre monoclínico e enxofre rômbico como - 297,2 kJ / mol e - 296,8 kJ / mol, respectivamente para a variação na transformação de 1 mol de enxofre rômbico em enxofre monoclínico conforme mostrado pela equação;

S (mon.) + O2 (g) -> SO2 (g)

Uma vez que são todos 1 mol cada, a mudança na entalpia será expressa como ∆H = ∆H2-∆H1

Dado ∆H2 = -296,8kJ / mol

∆H1 = -297,2kJ / mol

∆H = -296,8 - (- 297,2)

∆H = -296,8 + 297,2

∆H = 297,2-296,8

∆H = + 0,9kJ / mol

Portanto, a mudança na entalpia da equação é + 0,9kJ / mol
