- 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?
