Answer:
1.03M
Explanation:
mass/molar mass = moles of solution
50 g / (80+1) = 0.617 mol HBr
molarity*volume = moles
M*0.600 L = 0.617 mol
M = 0.617/0.600 = 1.03 M
Answer:
It's coefficient to the front of each element that requires it.
Explanation:
It is coefficient to the front of each element or compound that requires it. Essentially you are multiplying the amount of atoms or compounds on one side to match the amount on the other side.
Answer:
![K_{c} = [\text{C}]^{2}[\text{[D]}](https://tex.z-dn.net/?f=K_%7Bc%7D%20%3D%20%5B%5Ctext%7BC%7D%5D%5E%7B2%7D%5B%5Ctext%7B%5BD%5D%7D)
Explanation:
The general formula for an equilibrium constant expression is
![K_{c} = \dfrac{[\text{Products}]}{[\text{Reactants}]}](https://tex.z-dn.net/?f=K_%7Bc%7D%20%3D%20%5Cdfrac%7B%5B%5Ctext%7BProducts%7D%5D%7D%7B%5B%5Ctext%7BReactants%7D%5D%7D)
Solids and liquids are not included in the equilibrium constant expression.
Thus, for this reaction,
![K_{c} = [\textbf{C}]^{\mathbf{2}}\textbf{[D]}](https://tex.z-dn.net/?f=K_%7Bc%7D%20%3D%20%5B%5Ctextbf%7BC%7D%5D%5E%7B%5Cmathbf%7B2%7D%7D%5Ctextbf%7B%5BD%5D%7D)
Photon is a packet of light energy. Both photon and electron contribute mostly to the quantum mechanics of the atom. Every particle in quantum mechanical model is explained as dual natured, that is has both particle and wave nature. Photons exhibit wave light properties like diffraction, interference, etc.,At the same time they exhibit particle properties like having a definite momentum and position. Similarly electrons and other microscopic particles exhibit both particle and wave nature.
Therefore, the correct answer is:
Both photons and electrons display particle and wave-like behaviour.
