Not completely sure, but it's an ionic bond so I'm sure it would be lead (II) nitride
Ag3PO4 would be silver phosphate.
The 3 means there are 3 molecules of H2O (water), and the 2 is a subscript and means there are 2 atoms of hydrogen (H) in one molecule.
The number in the subscript of a chemical formula tells the number of that atom in a molecule. For example, in H2O, the 2 tells you there are 2 hydrogen atoms in the water molecule. in C3H8, there are 3 carbon atoms and 8 hydrogen atoms as reflected by the 3 and 8 in the formula respectively.
The answer is 'subscript'
Solve for the masses of oxygen given 1 gram of Pb:For PbO:(1 g Pb)(1 mol Pb/207.2 g Pb)(1 PbO/1 Pb)(1 O/1 PbO)(16 g O/1 mol O) = 0.07722 g OFor PbO2:(1 g Pb)(1 mol Pb/207.2 g Pb)(1 PbO2/1 Pb)(2 O/1 PbO2)(16 g O/1 mol O) = 0.1544 g OFor Pb2O3:(1 g Pb)(1 mol Pb/207.2 g Pb)(1 Pb2O3/2 Pb)(3 O/1 Pb2O3)(16 g O/1 mol O) = 0.1158 g OGet the ratio by dividing the smallest mass of oxygen to the rest of the calculated masses then multiply it by a certain factor to make it a whole number:0.07722 / 0.07722 = 1 x 2 = 20.1544 / 0.07722 = 2 x 2 = 40.1158 / 0.07722 = 1.5 x 2 = 3ANSWER: 2:4:3
Lead (II) Nitrate
Lead (II) Nitrate
The charge of the Pb ion can be either +2 or +3.
2NO+5H(subscript 2)----->2NH(subscript 3)+2H(subscript 2)O
potassium bromide - KBr iron (III) sulfate - Fe[subscript 2](SO[subscript 4])[subscript 3] copper (II) chloride - CuCl[subscript 2] tetraphosphorous heptanitride - P[subscript 4]N[subscript 7] ammonium carbonate - (NH[subscript 4])CO[subscript 3]
The formula unit Ba(NO3)2 contains 6 oxygen atoms. (Multiply the subscript 3 in the nitrate ion by the subscript 2 after the parentheses close.)
if your on nova net ur SOL
Pb^3 PO4^2
NO. The subscript of 3 applies only to the oxygen (O) in CO3.
Ag3PO4 would be silver phosphate.
This reaction is:2 Al + 3 Pb(NO3)2 = 2 Al(NO3)3 + 3Pb
Lead I nitrite= PbNO2 Lead II nitrite= Pb(NO2)2 Lead III nitrite= Pb(NO2)3 Lead IV nitrite= Pb(NO2)4
