I’m not quite sure but it’d probably be solar panels
Answer:
V2= 5L
Explanation:
P1= 500kPa, V1= 3L, P2= 300kPa, V2=?
Applying Boyle's law
P1V1=P2V2
(500*3)= (300*V2)
V2= 5L
86198Rn => 24He + 84194Po
The radon is shown on the left, and the alpha particle, which is a helium nucleus, is shown of the right with the polonium.
Answer:
4.55x10⁻⁴ atm
Explanation:
When the balance is used, it first must be tared, it means that the weight of the vessel will be discounted, so the mass of the gas produced must be above 0.5 mg to be read in the balance.
The molar mass of the CO2 is 44 g/mol, so, for a mass of 0.5 mg = 0.0005 g, the number of moles is:
n = 0.0005/44
n = 0.000011 mol
The ideal gas law is:
PV = nRT
Where P is the pressure, V is the volume, R is the constant of the gases (0.082 atm.L/mol.K), and T is the temperature (30°C = 303 K), so:
P*0.6 = 0.000011*0.082*303
P = 4.55x10⁻⁴ atm
Answer:
Atomic models are important because, they help us visualize the interior of atoms and molecules, and thereby predicting properties of matter.
Explanation:
We study the various atomic models in our course of study because, it is important for us to know, how did people come to the present concept of an atom. How did physics evolve from classical to quantum physics.
All these are important for us to know and thus, knowledge about various atomic models, their discoveries and drawbacks and finally improvements based on scientific evidence present at that time is important for us to understand the underlying theory very well.
