I am pretty sure it is PH5

P=Phosphorus (charge of three)

H= Hydrogen (charge of one)

Penta= charge of 5

since it's Pentahydride, penta=5(takes Phosphorus' place of charge on hydrogen)

Since Hydrogen has a charge of one, it doesn't show on Phosphorus

Why pentahydride of nitrogen is not possible?

A pentahydride of nitrogen is not possible because nitrogen typically forms triple bonds with itself in molecular compounds, making it challenging for nitrogen to accommodate five hydrogen atoms. Additionally, the large size and electronegativity difference between nitrogen and hydrogen makes it energetically unfavorable for nitrogen to bond with five hydrogen atoms.


What is the name of the compound with the formula MgI2?

Magnesium bromide pentahydrate. (MgBr2.5H2O) NB 'mgbr25h2o'. is incorrectly written. When writing chemical formula a one-letter symbol is always a capital letter .e.g. 'H' hydrogen and 'O' oxygen. A two-letter symbol is always written ; first letter is a capital letter and the second letter is small/lower case. e.g. 'Mg' Magnesium and 'Br' Bromine. Prefixed numbers (Molar ratios) are full script. post script numbers indicating the number of a given atom are written subscript ; unfortunately I cannot show it on Answers. A 'Full stop/Period' is always placed between the given compound and the hydrate number.

What is a LTL formula that has no equivalent CTL formula?

The formula AF(p -> Xp) is such a formula. It's simple to see that the formula is a LTL formula and judging by its syntax, it's not a CTL formula. The proof that there is no equivalent CTL formula is a bit more complicated.
