What is the IUPAC(chemical name) of PH3? Wouldn't it be phosphorous hydride because it's not molecular(there is a metal and non-metal). I searched online, it says it's Phosphorous trihydride?

As with all of these problems, we assume there are $100*g$ of compound, and proceeed on this basis to derive the empirical formula by calculating the individual molar quantites. And...

Since 8x3=24 and since 12x3=36 you need to add 6oz of chemical B to have 24oz of chemical A and 36oz of chemical B. Take 1/3 of the total mixture...

Ionic bonds occur between anions and cations. And cations may be metallic, i.e., $M^(2+)$, or they may be non-metallic, i.e. ammonium salts, $NH_4^+$. And anions, while typically non-metallic, i.e. $X^-$...

The distinction between a molecular and non-molecular structure is one of the most important criteria with which to assess . But here, if we have an elemental molecule, we have...

$"Diphosphorus pentoxide"$, $P_2O_5$, consists of $P_4O_10$ molecules........

The problem provides you with the reactants, which are said to be white phosphorus, $"P"_ (4(s))$ oxygen gas, $"O"_ (2(g))$ and with the product, which...

Note that phosphorous is $P$. $therefore P+O_2rarrP_4O_10$ We have 1 P on the LHS, and 4 on the RHS. We have 2 O on the LHS, and 10 on...

I have been told that the major ingredient of rat poison is aluminum phosphide.

$CaH_2(s) + 2H_2O(l) rarr Ca(OH)_2(aq) + 2H_2(g)uarr$ The balanced equation gives a 1:1 stoichimetry between calcium hydride and dihydrogen gas, We need to (i) work out the molar quantity of...

The normal melting point of methanol is $-97.6$ $""^@C$. But here, clearly, we compare apples and oranges, by comparing a melting point, a transition from solid to liquid, to...
