You need to describe your model in more detail. Chemical equilibrium is the result of two opposite processes occurring e same rate. Does your model show that?

The reaction between the added solid and NaOH is: NaH2PO4 + NaOH --> Na2HPO4 + H2O 10.0gNaH2PO4 /120.0g/mol = 0.0833 moles NaH2PO4 initially. In the rection, the limiting reactant is NaOH. (0.150 L)(0.20 mol/L) = 0.030 mol NaOH 0.030 moles of NaOH ---> 0.030 moles Na2HPO...

You can have three different chemical equations going on at the same time: C5H12 + 8O2 ==> 5CO2 + 6H2O 2C5H12 + 11 O2 ==> 10CO + 12H2O C5H12 + 3O2 ==> 5C + 6H2O The relative amounts of C5H12 undergoing each reaction simultaneously varies depending on the availability ...

The length of a carbon chain has more to do with melting and boiling points than the number of bonds. Double bonds tend to lower the melting point if the chain is in a "cis-" configuration. As BobPursley pointed out, the question is not clear enough for a definite a...

The question is to find grams of CaH2. The balanced chemical equation is: CaH2 + 2H2O --> Ca(OH)2 + 2H2 This mole ratio must be taken into account. Find the moles of H2 as DrBob showed you, then multiply by 1/2 to get moles of CaH2. Finally convert moles of CaH2 to grams.

The six orbitals on the central atom, As, are sp^3d^2 hybrids. That is the kind of hybridization you have in an octahedral structure, "XY6". Each of the hybrid orbitals on the As atom is forming a sigma bond with the half filled p orbital on an F atom.

HCl is a molecular compound with relatively weak intermolecular attractions. It is a gas at room temperature. NaCl is an ionic solid because of the strong ionic attraction between the Na+ and Cl- ions. The physical properties (state at room temperature, melting and boiling poi...

If you wanted to know what amount of sodium chloride was delivered into another container, you would weigh the vial with the salt in it, then weigh the "empty" container which may have traces of salt stuck in it.
