H-H
A covalent bond and one sigma bond between the two hydrogen atoms as they only have the one electron apiece to share in the covalent bond.
CaH2, calcium hydride, is ionic., Ca2+ 2H-
The bond line formula for methane is CH4.
It is 6-chloro-1,1-dioxo-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-sulfonamide with the formula, C7H8ClN3O4S2
PBr is a polar covalent bond. To figure this out you must you an Electronegativity Table. On this table Br=2.8 and P=2.1. Subtract and you get .7. If your answer (in this case .7) falls between .5 and 1.9, then you have yourself a polar covalent bond.
The bond type present in the molecule CH2Cl2 is a covalent bond.
A=1/2h(a+b)
A covalent bond involve sharing of electrons.
Penicilline is not a 'bond' but a compound. The chemical formula is: C16H18N2O4S (the original PenG, benzylpenicilline)
P= 2l+2w
The chemical formula CH3COCH3 2H corresponds to the compound acetone (CH3COCH3) with two hydrogen ions (2H) associated with it. The two hydrogen ions could indicate that the solution is acidic.
2h + 2h + 2h = 6h
CaH2, calcium hydride, is ionic., Ca2+ 2H-
The bond line formula for methane is CH4.
The formula for H plus 1 plus H minus 1 is 2H. This is because the +1 and -1 charges cancel each other out, leaving only the H atom.
It is 6-chloro-1,1-dioxo-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-sulfonamide with the formula, C7H8ClN3O4S2
This is a good question, and you need to know the quadratic formula let A = area b = width h = height P = perimeter A = bh b = A/h P = 2b + 2h P = 2A/h +2h = (2h^2 + 2A)/h Ph = 2A + 2h^2 2h^2 - Ph + 2A = 0 use quadratic formula to solve: h =( P +/- SQRT(P^2 -16A))/4 This gives both sides b and h using plus then minus the square root
2h means two handed
