I didn't mean it!I mean, seriously what's your problem?You are being so mean.
"bon" mean "good" and partir mean "to leave"
bisit mean
moron mean>?
what does it mean
PH4 could refer to phosphine, which is a chemical compound with the formula PH3. It is a colorless, flammable gas.
The oxidation number of PH4 cannot be determined because phosphorus (P) does not have a fixed oxidation number in this compound.
The bond angle in PH4 is higher than PH3 because PH4 has a tetrahedral molecular geometry with bond angles of about 109.5 degrees, while PH3 has a trigonal pyramidal molecular geometry with bond angles of about 107 degrees. This difference in bond angles is due to the presence of an additional hydrogen atom in PH4 compared to PH3.
tetrahedron
PH4 has sp3 hybridization. This means that the phosphorus atom forms four sigma bonds using one 3s orbital and three 3p orbitals.
Any acid solution with 1.00*10-4 mol/L H3O+
The pH value of acid rain typically ranges from 4 to 5.6.
The pH level of boric acid is typically around 5.0 to 6.0 in water. It is considered a weak acid.
To create a solution with a pH of 4 using vinegar, you can mix approximately 1 part vinegar with 10 parts water.
chemistry and physics can tells you the aubometer of the ph2 and the ph4
Since the conjugate acid is supposed to be just the addition of an H+, then it should be either HPH3+ or PH4+, phosphonium cations, resulting from protonation of phosphine. It has a molar mass of 35.01 g/molThe (positive) cations are much like the analogue ammonium ions NH4+.
When mixing a solution at pH 4 with a solution at pH 8, the final pH will be between 4 and 8. The resulting pH will depend on the ratios of the two solutions being mixed. If equal volumes are mixed, then the final pH will likely be around 6.
