Why is the bond angle in PH4 higher than PH3?
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.
What are the unit of air pressure?
chemistry and physics can tells you the aubometer of the ph2 and the ph4
What condenser setting value do you want when you are using 100x objective lens?
When using a 100x objective lens, it is recommended to set the condenser to its highest position (also known as the "oil immersion" position). This helps increase the resolution and contrast of the image by optimizing the light entering the lens.
How many fold decreas in acidity pH4 to pH7?
There is a 1,000-fold decrease in H+ concentration when the pH increases by 3 units (pH 4 to pH 7). This is because the pH scale is logarithmic, so each unit change represents a 10-fold change in H+ concentration.
Is phosphorus a positive or a negative ion?
Phosphorus typically forms a negative ion, known as a phosphate ion (PO4^3-), when it gains electrons. However, in some compounds, phosphorus can also form positive ions, such as in phosphonium (PH4^+). The charge of the phosphorus ion depends on the context and the specific chemical reactions it undergoes. Generally, it is more common to encounter phosphorus in its anionic form in biological and environmental contexts.
What is PH4?
PH4 could refer to phosphine, which is a chemical compound with the formula PH3. It is a colorless, flammable gas.
What is the oxidation number of PH4?
The oxidation number of PH4 cannot be determined because phosphorus (P) does not have a fixed oxidation number in this compound.
Why is the bond angle in PH4 higher than PH3?
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.
What is the molecular geometry of PH4 plus?
tetrahedron
What is the hybridization of PH4?
PH4 has sp3 hybridization. This means that the phosphorus atom forms four sigma bonds using one 3s orbital and three 3p orbitals.
What substance has pH4?
Any acid solution with 1.00*10-4 mol/L H3O+
Suggest a possible value for the PH value of acid rain?
The pH value of acid rain typically ranges from 4 to 5.6.
What is the pH level of Boric Acid?
The pH level of boric acid is typically around 5.0 to 6.0 in water. It is considered a weak acid.
Exact mix of water and vinigar to get ph4?
To create a solution with a pH of 4 using vinegar, you can mix approximately 1 part vinegar with 10 parts water.
What are the unit of air pressure?
chemistry and physics can tells you the aubometer of the ph2 and the ph4
Conjugate acid of Ch3NH2?
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+.
What is the pH when you mix ph4 with ph8?
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.
