Answer:

A spinning ball creates a "Centrifugal Force" because you give it the "energy" to spin. A ball that is not moving does not require any external energy to keep it still.

A sample of pure NO2 is heated to 335 ∘C at which temperature it partially dissociates according to the equation 2NO2(g)⇌2NO(g)+
vodka [1.7K]

The equilibrium constant for the reaction is 0.00662

Explanation:

The balanced chemical equation is :

2NO2(g)⇌2NO(g)+O2(g

At t=t  1-2x ⇔ 2x + x moles

The ideal gas law equation will be used here

PV=nRT

here n= \frac{w}{W} = \frac{w}{V}= density

P = \frac{density RT}{M}       density is 0.525g/L, temperature= 608.15 K, P = 0.750 atm

putting the values in reaction

0.75 = \frac{0.525 x 0.0821 x 608.15 }{M}

  M    = 34.61

         

to calculate the Kc

Kc=\frac{ [NO] [O2]}{NO2}

  \frac{1-2x}{1+x} x M NO2 + \frac{2x}{1+x} M NO+ \frac{x}{1+x} M O2

Putting the values as molecular weight of NO2, NO,O2

\frac{46(1-2x) +30(2x)+32x}{1+x}

34.61= \frac{46}{1+x}

x= 0.33

Kc= \frac{4x^2)x}{1-2x^2}

    putting the values in the above equation

Kc = 0.00662

Do you think flowers are important to mindkind? If yes explain why in your own words please it would mean a lot!!
Gemiola [76]

Answer:

Flowers play a crucial role in our lives; they have been used for generations to express the thoughts and feelings words cannot fully explain. Mother nature is the short term used to describe how nature gives life and nurture as a mother does for her children. As humans, we are part of mother nature's plan. We are also connected to plants and flowers, and some of the benefits have been passed to the next generation and will always be. We can control the air that we breathe, the aura around us, how we feel, and the things we attract in life. Other than only gifting your loved ones with flowers on special occasions, you can make the best and lasting impressions on your loved ones with a flower plant gift. This gesture shows that you understand how flowers are important in our life. To shed light on the importance of flowers in our life, here is a blog that will give five importance of flowers
