FC(C) = 4 - 0.5*8 - 0 = 0) FC(Cl) = 7 - 0.5*2 - 6 = 0
It is B, smoke and air pollution can stress the lungs and cause things like Respiratory distress if not wearing a proper mask. That is why in places with massive amounts of air pollution many people will wear face masks.
Explanation:
Ca3(PO4)2 1 mole has 310.2 g
Ca3(PO4)2 4.3 × 10^-4 moles has 4.3 × 10^-4 × 310.2
= 1,333.86 × 10^-4
= 1.334 × 10^-1
OR 0.1334 g
As the electrons are pushed more by the battery, they move faster through the circuit
<span>remember that all elements want to have no valence electrons, they want to be like the noble gases.
Oxygen has six valence electrons, which means that it needs to gain two to become stable.
it takes much more energy for oxygen to lose its 6 valence electrons than it would be to gain 2.
>>When atoms form compounds, they become stable
