Use the ideal gas formula-----> PV= nRT
P= 2.50 atm
V= 250 mL= 0.250 L
n= 0.100 moles
R= 0.0821 atmxL/molesxK
T= ?
T= PV/nR
T= (2.50 atm x 0.250 L) / (0.100 moles x 0.0821)= 76.1 K
Answer:
- <em>On the atomic level, energy and matter exhibit the characteristics of </em><u>both waves and particles.</u>
Explanation:
The dual behavior of subatomic particles as waves and particles is known as the wave - particle duality.
And this principle is the basis of the quantum theory.
Such principle is widely applied to the electrons; i.e., the electrons posses wave and particle propeties, which must be understodd as that some of their properties may be explained as if they were particles and others as if they were waves.
For example, from the particle point of view electrons have mass. You can find in internet that the mass of one electron is about 9.1093837015×10⁻³¹ kg or about 1/1836 times the mass of one proton.)
Since, the point of view of the wave characteristics, electrons have wavelength, Louis de Broglie deduced the equation that relates the wavelength and the mass, through this realtion:
- Wavelength (λ) = Planck’s constant (h) divided by the product of the mass (m) and the the speed (v) of the particle.
λ = h / mv
Answer:
D
Explanation:
If delta G at standard conditions is positive, then the reaction will always be nonspontaneous in the forward direction.
There are no similarities between the two, though there are many differences!<span />
