Answer:
1 mole of zinc has 6.023 x 1023 atoms
So, 4.1 moles will have 4.1 x 6.023 x 1023 atoms = 24.694 x 1023 atoms
Explanation:
Answer:
They include: Chemical nature of the pollutant - how active and toxic it is to humans, plants and animals; Concentration - the amount of the chemical per unit volume of air, water, soil, and; Persistence or longevity - how long the pollutant remains in the environment in its harmful form.
Explanation:
Air pollutants like ozone, particulate matter, carbon monoxide, nitrogen oxide, sulfur dioxide, lead cause atmospheric pollution which regards to ozone depletion, GH effect, climate change and human health effects. If anyone say the main factors of air pollution beyond of industry, means of transportation, solid waste generation and urbanization.
Growing urbanization and industrialization grows more pollution. Due to a large number of population in the world, more pollution is generated. Specifically if we talk about air pollution, due to steady increase in number of industries, the gradient level is deteriorating day by day. There is no good if we just talk about sustainable development if we are not following it.
Answer:
Equilibrium constant of the given reaction is ![1.3\times 10^{-29}](https://tex.z-dn.net/?f=1.3%5Ctimes%2010%5E%7B-29%7D)
Explanation:
....![(K_{p})_{1}=5.3](https://tex.z-dn.net/?f=%28K_%7Bp%7D%29_%7B1%7D%3D5.3)
....![(K_{p})_{2}=2.1\times 10^{30}](https://tex.z-dn.net/?f=%28K_%7Bp%7D%29_%7B2%7D%3D2.1%5Ctimes%2010%5E%7B30%7D)
The given reaction can be written as summation of the following reaction-
![2NO+Br_{2}\rightleftharpoons 2NOBr](https://tex.z-dn.net/?f=2NO%2BBr_%7B2%7D%5Crightleftharpoons%202NOBr)
![N_{2}+O_{2}\rightleftharpoons 2NO](https://tex.z-dn.net/?f=N_%7B2%7D%2BO_%7B2%7D%5Crightleftharpoons%202NO)
......................................................................................
![N_{2}+O_{2}+Br_{2}\rightleftharpoons 2NOBr](https://tex.z-dn.net/?f=N_%7B2%7D%2BO_%7B2%7D%2BBr_%7B2%7D%5Crightleftharpoons%202NOBr)
Equilibrium constant of this reaction is given as-
![\frac{[NOBr]^{2}}{[N_{2}][O_{2}][Br_{2}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BNOBr%5D%5E%7B2%7D%7D%7B%5BN_%7B2%7D%5D%5BO_%7B2%7D%5D%5BBr_%7B2%7D%5D%7D)
![=(\frac{[NOBr]}{[NO][Br_{2}]^{\frac{1}{2}}})^{2}(\frac{[NO]^{2}}{[N_{2}][O_{2}]})](https://tex.z-dn.net/?f=%3D%28%5Cfrac%7B%5BNOBr%5D%7D%7B%5BNO%5D%5BBr_%7B2%7D%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D%29%5E%7B2%7D%28%5Cfrac%7B%5BNO%5D%5E%7B2%7D%7D%7B%5BN_%7B2%7D%5D%5BO_%7B2%7D%5D%7D%29)

![=\frac{(5.3)^{2}}{2.1\times 10^{30}}=1.3\times 10^{-29}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%285.3%29%5E%7B2%7D%7D%7B2.1%5Ctimes%2010%5E%7B30%7D%7D%3D1.3%5Ctimes%2010%5E%7B-29%7D)
Volume= h*l*w
2*3*2=12cm
You're answer is 12cm. Hope it helps!
Answer:
1. Uniform, non visible
2. Visible, non uniform
3. Uniform, non visible
4. Visible, non uniform
5. Visible, non uniform
Explanation:
A heterogeneous mixture is simply any mixture that is not uniform in composition — it's a non-uniform mixture of smaller constituent parts. By contrast, a mixture that is uniform in composition is a homogenous mixture
visible state of matter is when you can easily difference two components of a mixture
non visible is when the state of the matter in the substance is not visible to the eye, it can't be differentiated
