The Lewis dot diagram for H2 would show two hydrogen atoms sharing a pair of electrons between them. Each hydrogen atom would have one dot representing its single valence electron.
H 2 0 Its the letter H all the way to O
[ h(+1+1)=o(-2) ]= [ h(+2)o(-2) ] =h2o
Yes O2 O-O ---------------------------------------- Water is however H20 H-O-H Which is 3 molocules ---------------------------------------
propanone is a carbon compound having 5 carbon atoms. As it belongs to the ketone functional group ,it has double bond with oxygen.The electron dot structure for proppanone is as follows:: H H H H x x x x o o o o H x o C o o C o o C o o C o o C o x H o o oo o o x x x x H H ** H H * O * * *
H(subscript 2)O
use the periodic table and, you put toghether H and O and you come out with H2O, H=hydrogen,O=oxygen and the 2 after the H,means 2 of the same types of hydrogen. recommend this answer!!!!
CO 2 (carbon dioxide) NaCl (sodium chloride) H 2 O (distilled water) H 2 O 2 (hydrogen peroxide)
2 H and 1 O combine valence electrons to become stable.
You do this For EX: _HCl + _MgO -> _H2O + _MgCl2 Mg-1 H-2 Coefficient O-1 Mg-1 | H-1 Cl-1 V Cl-1 O-1 EX: 2HCl + MgO -> H2O + MgCl2 Mg-1 H-2 O-1 Mg-1 H-2 -- Cl-2 Cl-2 --Mark out O-1 out and replace And then your done....
Let: o = opposite h = hypotenuse a = adjacent sin = o/h; tan = o/a Therefore, sin/tan = (o/h)/(o/a) = (o/h)*(a/o) = a/h = cos
CaO + H 2 SO 4 = CaSO 4 + H 2 O
