What is the equilibrium concentration of ibr?

Physics
1 answer:
asambeis [7]3 years ago
3 0
IBR is the thermal decomposition of iodine(I) bromide to produce iodine and bromine. This reaction takes place at a temperature of over 40,5°C and is written as: 

 <span>2IBr ⇄ I2 + Br2
</span>
Equilibrium is a state of dynamic balance where the ratio of the product and reactant concentrations is constant.<span> You can calculate the equilibrium concentration if you know the equilibrium constant Kc (Kc=I^2*Br^2/IBR^2) and the initial concentration for the reaction. The initial concentration is obtained from ICE Table.</span>

A force of 16.88 n is applied tangentially to a wheel of radius 0.340 m and causes an angular acceleration of 1.20 rad/s2. What
telo118 [61]

Answer:

4.78 kg/m^2.

Explanation:

τ = Iα

Where,

τ = torque, around a defined axis (N∙m)

I = moment of inertia (kg∙m2)

α = angular acceleration

= 1.2 rad/s^2

τ = F * r

= 16.88 * 0.34

= 5.74 N.m

Therefore, I = 5.74/1.2

= 4.78 kg/m2

Salutations!

What happens to baking soda when you heat it up!

When you heat up baking soda, it loses carbon dioxide which tends to crest bubbles. This is what makes it quite light and fluffy.

Hope I helped :D

Does the area of contact effect the frictional force . explain?​
OlgaM077 [116]

Answer:

The force due to friction is generally independent of the contact area between the two surfaces. This means that even if you have two heavy objects of the same mass, where one is half as long and twice as high as the other one, they still experience the same frictional force when you drag them over the ground.

A large capacitor in an air conditioner is typically connected to the potential difference provided to your house (120 V). Altho
fomenos

Answer:

A=7.72\times 10^{-18}\ m^2

Explanation:

Given:

  • the voltage of the source, V=120\ V
  • distance of separation between the capacitor plates, d=2\times 10^{-3}\ J
  • energy of the capacitor, U=0.25\ J

Assuming that there is free space between the plates, so the permittivity, \epsilon=9\times 10^{9}\ N.m^2.C^{-2}

<u>We have the energy stored in a capacitor as:</u>

U=\frac{1}{2}\times \frac{\epsilon.A.V^2}{d}

0.25=0.5\times \frac{9\times 10^{9}\times A\times 120^2}{2\times 10^{-3}}

A=7.72\times 10^{-18}\ m^2
