Ok so I have got these (down below) I just need the last 6 could anyone pls do those? Thank you if you do ur the best evr 20 points! Mg protons-12 Neutrons-12 electrons- 12

Element: O Atomic mass unit: 16 Atomic number: 8 Protons: 8 Electrons: 8 Neutrons: 8

Element: Cl Atomic mass unit: 35 Protons: 17 Electrons: 17 Neutrons: 18

Element: Ni Atomic mass unit: 59 Atomic number: 28 Protons: 28 Electrons: 28 Neutrons: 31

Calculate the mass of an object that has a momentum of 100kg x m/sec and velocity of 4 m/sec

Red light strikes a metal surface and electrons are ejected. if violet light is now used with a 10% greater intensity, what will happen to the ejection rate (number of ejected electrons per second) and the maximum energy of the electrons? a) greater ejection rate; same maximum energyb) same ejection rate; greater maximum energyc) greater ejection rate; greater maximum energyd) same ejection rate; same maximum energye) none of the above answers are correct

Explain why you think this diagram shows what happened to the carbon in the biodome.
