Answer:

Trend in ionic character of bonds: Cs-F > Si-C > Br-Cl > Cl-Cl    

                                                           (most)                          (least)                    

Explanation:

We know that, percentage ionic character of a bond is proportional to electronegativity difference between two constituting atoms.

                   Atom                                                  Electronegativity

                     Cs                                                              0.7

                      F                                                                4.0

                     Cl                                                                3.0

                     Br                                                               2.8

                      Si                                                                1.8

                     C                                                                 2.5

                Bond                                  Electronegativity difference

               Cs-F                                                                   3.3

               Cl-Cl                                                                   0.0

                Br-Cl                                                                  0.2

                Si-C                                                                    0.7

    So trend in ionic character of bonds:

     Cs-F > Si-C > Br-Cl > Cl-Cl

     (most)                         (least)

What is the molarity of a solution made by adding 0.720 mole of NaOH to 2.40 liters of water
WITCHER [35]

Answer:

Molarity = 0.3 M

Explanation:

Given data:

Moles of NaOH = 0.720 mol

Volume of water = 2.40 L

Molarity = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Molarity = 0.720 mol / 2.40 L

Molarity = 0.3 mol/L

Molarity = 0.3 M

Given the following equation: 2 K3N ---> 6 K + N2 How many moles of N2 can be produced by letting 12.00 moles of K3N react?
myrzilka [38]
The answer will be 12 nitrogen or N2 will be produced because if you changed the coefficient to 12 on the reactant side and distribute, the nitrogen would be 12 when distributed and what happens on one side has to equal to the other side, which is the product side.

Help please!! I need to turn this in by midnight! EST
nignag [31]

Answer:

FIREWORKS : WHEN FIREWORKS EXPLODE THEY EXPEL SMOKE WHICH IS A FORM OF GAS AND THEY LIGHT UP WHICH IS ANOTHER CHEMICAL REACTION AND OF COURSE THE WHOLE FIREWORK GETS HOT ( Temperature rises )

Explanation:

you could see your reaction happens when original substance changes in color temperature formation produces light or gas in many other things

( besides it's original form! )

answer what changed from it's original form!

ex: baking a cake:

the cake change form ( rising ) due to heat ( rising temperature )

REACTION WAS:

- formation of precipitate ( solid to settle out of a solution )

- change I'm temperature to bake the cake

Extra:

you got this!

I hope I helped even just a little!
