"What makes a bond polar"?

Chemistry
1 answer:
r-ruslan [8.4K]3 years ago
8 0

Answer:

The answer to your question is: letter A.

Explanation:

A Covalent bond polar is between 2 non metals where one atom is bigger than the other one so the distribution of charges creates this polarity.

A. One atom attracts shared electrons more strongly than the other atom  This is the correct definition of bond polar, one element is bigger and stronger than the other element.

B. One atom has transferred its electrons completely to another atom  This definition is incorrect, it is the definition of ionic bonding.

C. A sea of electrons has been created between the elements  This definition is incorrect for the polar bond, it describes a metallic bonding.

D. Two atoms are sharing electrons with equal attraction This definition is incorrect for a polar bond, but is the correct definition for nonpolar bonding.

Consider the reaction. mc014-1.jpg How many grams of methane should be burned in an excess of oxygen at STP to obtain 5.6 L of c
garri49 [273]
The reaction for the combustion of methane can be expressed as follows.
                           CH4 + 2O2 --> CO2 + 2H2O
We solve first for the amount of carbon dioxide in moles by dividing the given volume by 22.4L which is the volume of 1 mole of gas at STP.
                            moles of CO2 = (5.6 L) / (22.4 L/1 mole)
                             moles of CO2 = 0.25 moles
Then, we can see that every mole of carbon dioxide will need 1 mole of methane
                              moles methane = (0.25 moles CO2) x (1 moles O2/1 mole CO2)
                                                    = 0.25 moles CH4
Then, multiply this by the molar mass of methane which is 16 g/mole. Thus, the answer is 4 grams methane.
