Mild fungal skin diseases can look like a rash and are very common. Fungal diseases in the lungs are often similar to other illnesses such as the flu or tuberculosis.Some fungal diseases like fungal meningitis and bloodstream infections are less common than skin and lung infections but can be deadly.ild fungal skin diseases can look like a rash and are very common.

Up here we had one ring and we had an HDI equal to one. Up here we had one double bond and an HDI equal to one. We could also calculate the HDI using a formula. So we could write that the hydrogen deficiency index is equal to one-half times what's in the parenthesis. Which is two times the number of carbons plus two. That's the whole two n plus two idea. Minus the number of hydrogens. So let's go ahead and do it for this molecular formula with six carbons and six hydrogens.
To balance the charges, we require two nitrate ions per lead (II) ion, and so lead (II) nitrate is #Pb(NO_3)_2#. The potassium ion is #K^+# and the iodide ion is #I^-#. The two charges balance in a #1 : 1# ratio, so potassium iodide is simply #KI#. In lead (II) iodide, the charges balance in a #1 : 2# ratio, so the formula is #PbI_2#. Finally, in potassium nitrate, the charges balance in another #1 : 1# ratio, giving a formula of #KNO_3#. The symbol equation is as follows:
