Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

 

                Less than 0.4 then it is Non Polar Covalent

                

                Between 0.4 and 1.7 then it is Polar Covalent 

            

                Greater than 1.7 then it is Ionic

 

For CaCl₂,

                    E.N of Chlorine       =   3.16

                    E.N of Calcium        =   1.00

                                                   ________

For C-H Bond in C₆H₁₂O₆,

                    E.N of Carbon            =   2.55

                    E.N of Hydrogen        =   2.20

                                                   ________

                    E.N Difference                 0.35         (Non-Polar Covalent Bond)


For C-O Bond in C₆H₁₂O₆,

                    E.N of Oxygen           =   3.44

                    E.N of Hydrogen        =   2.55

                                                   ________

                    E.N Difference                 0.89         (Polar Covalent Bond)


For O-H Bond in C₆H₁₂O₆,

                    E.N of Oxygen           =   3.44

                    E.N of Hydrogen        =   2.20

                                                   ________

                    E.N Difference                 1.24         (Polar Covalent Bond)


For MgO,

                    E.N of Oxygen              =   3.44

                    E.N of Magnesium        =   1.31

                                                   ________

                    E.N Difference                    2.13         (Ionic Bond)


For Na₂O,

                    E.N of Oxygen              =   3.44

                    E.N of Sodium              =   0.93

                                                   ________

                    E.N Difference                    2.51         (Ionic Bond)


For SiO₂,

                    E.N of Oxygen              =   3.44

                    E.N of Silicon                =   1.90

                                                   ________

                    E.N Difference                    1.54         (Polar Covalent Bond)

Does gravity exist without air?
sveticcg [70]

Mass is required for gravity. Higher mass implies higher gravitational drag. Most of these thoughts are tied to other planets without atmospheres, or the moon. The moon doesn't have any air or atmosphere and it pulls the Earth water.

Please correct any mistakes in my answer!! I'd be happy to fix it!! :)

1) will water boil at 100 degrees celsius whether it has 20 mg or 200 mg of weight?
aleksley [76]

Answer:

yes water boils at 100 degree Celsius but the boiling point water is different at different place because of the altitude of that place. For example boiling point of water is 96 decree Celsius.

No the 2 solutions don't boils at same time. it's because of their volume.

if the volume is more then it takes more time to boli. and vice versa

The empirical formula of styrene is CH; its molar mass is 104.1 g/mol. What is the molecular formula of styrene
frez [133]
  • The atomic mass of carbon is 12.011 g/mol.
  • The atomic mass of hydrogen is 1.00794 g/mol.

This means the molar mass of CH is

12.011+1.00794=13.01894 \text{ g/mol}

Dividing the given molar mass by this,\frac{104.1}{13.01894} \approx 8

This means the molecular formula is \boxed{\text{C}_{8}\text{H}_{8}}

What do agents such as chemicals, elevated temperatures, ionizing radiation, and viruses have in common?
Leni [432]

Answer:

All of them affect the DNA

Explanation:

Chemicals are compounds that can pass through cell membranes and modificate the DNA, elevated temperatures can denaturalize the cell and therefore damage the DNA, ionizing radiation can pass through cell organelles and reach the nucleus affecting the DNA, and viruses inject its DNA into the genome and modify it.
