The molar mass is what would you find on the periodic table and it is used in the mole conversions within chemistry. So the answer would have to be A: the mass in grams of one mole of a substance.
Which list of elements contains two metalloids?(1) Si, Ge, Po, Pb (3) Si, P, S, Cl(2) As, Bi, Br, Kr (4) Po, Sb, I, Xe

The answer is (1). Si and Ge are both metalloids (semimetals)
Solid: The particles (i.e. atoms or compounds) vibrate about their fixed positions and are relatively very close to each other.
Liquid: The particles move about relatively VERY SHORT distances and move freely, flowing around other particles at high speeds.
Gas: The particles move far from each other about relatively very great distances at high speeds.
Answer:
well the first one is something i can get but the second one is something you can google up but here's he first one i tried:
It represents 50, 55, and 65.
3: It effected the speed as if it was heaver it would be harder to pick up and faster than a slow light object like a feather or a lego
alright i tried hard as i can, sorry if i end up putting in the wrong
awnser
sleep well ^-^
Answer is: <span>5. one pair of electrons and two lone electrons.
Electron configuration for carbon: </span>₆C 1s² 2s² 2p².
Valence electrons are in 2s and 2p orbitals. There is one pair of electrons in 2s orbital and two lone electrons in 2p orbital with the same electron spin. Carbon is in group 14 of periodic table group.
