as temperature increases, what does vapor pressure do?

Equal volumes of all gases at the same temperature and pressure contain the same number of molecules(Avogardro's law)

what is the formula for change in temperature?

DSE 2019: suggest how the effect of A on the rate of reaction can be studied using the above set-up

the average distance of electrons to the nucleus - the larger the value, the farther the elec. is from the nucleus - n= 1,2,3, etc.

3 orbitals, can hold a max. of 6 electrons- dumbbell shape

1 orbital, can hold a max. of 2 electrons- spherical shape

1. an electron is only found in specific orbits around the nucleus2. each possible electron orbit has a fixed energy (energy level)3. the energy levels get higher + closer together as you move farther from the nucleus

5 orbitals, can hold a max. of 10 electrons- 4 leaf clover shape, or 2 lobes + a donut

the orientation of the orbital in 3D spaces = 0p = -1,0,1d = -2,-1,0,1,2f = -3,-2,-1,0,1,2,3

1. electrons start at their ground state2. when they absorb energy, they jump to a higher energy level (excited state)3. as they lose energy to fall back down to the ground state, they lose some of that energy in the form of visible light

n = 1, 1 subleveln = 2, 2 sublevelsn = 3, 3 sublevels n = 4, 4 sublevels...

represents the size + energy of atomic orbitals; it specifies the atom's principal energy levels

7 orbitals, can hold a max. of 14 electrons

- when there is high frequency, there is high energy + a short wavelength - low frequency means low energy + longer wavelength(energy is proportional to frequency)

when filling orbitals of equal energy, electrons fill them singly first, with parallel spins

we can't know both the position + speed of a particle with perfect accuracy at the same time

What is the main product for the electrolysis of chloride at very low concentration, dilute Sodium chloride?

Is the curent the same flowing through cells connected in series ?

What is the product with concentrated chloride electrolysed?
