Calcium nitrate, also called Norgessalpeter (Norwegian saltpeter), is an inorganic compound with the formula Ca(NO3)2. This colourless salt absorbs moisture from the air and is commonly found as a tetrahydrate. It is mainly used as a component in fertilizers but has other applications.
- Ca(OH)2 has 1 Ca atom, 2 O atoms and 2 H atoms. Since they are not balanced, I need to put something on the left to give more on that side. Try 2 HNO3, which gives 6 O atoms, and I had 2 from the Ca(OH)2 already, so I have a total of 8 O atoms now.

2) The balanced molecular equation for complete neutralization of H2SO4 by KOH in aqueous solution is _____. A) 2H+ (aq) + 2OH- (aq) → 2H2O (l)
- The products of the neutralization reaction between HNO3(aq) and Ca(OH)2(aq) are: A. Ca(NO3)2 + 2H2O. B. CaNO3 + 2H2O. C. CaNO3 + H2O.
K2Cr2O7 Fe(NO3)3 CuOH MgCO3 Ag3PO4 BaSO4 PbCl2 CaCl2 Write the balanced molecular equation given the following information: silver nitrate + sodium carbonate ( silver carbonate + sodium nitrate. Write the ionic equation from this molecular equation. Underline the “spectator ions.” 2 Fe(NO3)3(aq) + 3 Ca(OH)2(aq) ( 2 Fe(OH)3(s) + 3 Ca(NO3)2(aq)
- C3H4O3 33. (a) CH2O; (b) C2H4O 35. (a) ethanol (b) methoxymethane, more commonly known as dimethyl ether (c) These molecules have the same chemical composition (types and number of atoms) but different chemical structures. They are structural isomers.
Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Compound states [like (s) (aq) or (g)] are not required. You can use parenthesis or brackets . How To Calculate Limiting Reagents. Coming Soon!
- When solid Pb(NO 3) 2 is place on one side and solid KI on the other, PbI2 precipitates in the center. Pb(NO 3) 2 (aq) + 2KI(aq) → PbI 2 (s) + 2KNO 3 (aq) To Conduct Demonstration. Place petri dish on stage of overhead projector. Pour water into dish to a depth of ¼” to 3/8” Scoop a small amount of Pb(NO3)2 into the water at one side of ...
