I've never heard of nitrochloric acid, but perhaps you are looking for
aqua regia, which contains both
nitric acid and
hydrochloric acid. It is one of the few acids able to dissolve gold.
I'm not quite sure carboxylic acids are all strong acids. I'd think of them as weak acids, with the conjugate salts being relatively strong bases. --

That's would be a misleading statement, even though it contains a grain of truth. Most hydrocarbons are not very acidic. They don't neutralise most bases. We could go into a long discussion about how easily various hydrocarbons can be deprotonated and so on, but it would be a distraction. Almost any molecule can be depronated (given a strong enough base like
BuLi) but we only call them acids if they are deprotonated fairly easily by normal-strength bases like
NaOH. If you mix
acetic acid and sodium hydroxide, a salt forms,
sodium acetate. If you mix
hexane with NaOH, nothing happens. That's why we say acetic acid is an acid but hexane isn't. --

Again, acetylene is not what we'd normally refer to as an acid, because it takes very strong bases like BuLi to deprotonate it. The pKa of alkynes is about 25, compared to 16 or so for alcohols, 14 for water, 10 for phenols, 5 for carboxylic acids and about 0 for mineral acids like HCl. This means an alkyne is about a billion times less acidic than an alcohol, which itself is not very acidic (ethanol, for example, is not going to burn a hole in your trousers, whereas HCl will). Acetylene is much more acidic than alkanes, but much less acidic than proper acids. That's why we don't call it an acid - it only donates protons to über powerful bases. --

As you can clearly see by reading that page, the structure was originally thought to be a carboxylic acid. As you can clearly see by reading that page, the is is as acidic as carboxylic acids, not a normal hydrocarbon.
