Just to show of a bit more, you should also accept Gospadin which is Russian for citizen. I learned Russian in Soviet times. The correct greeting to a policeman was Dobry Den Tovarish Militsionare (good day Comrade Policeman). To which the correct response was Dobry Den Tovarish Gospadin (Good Day Comrade Citizen).
Though I don't exactly know if the term Gospadin (gentleman) would be used in the Soviet union, considering that it came from the term Gospod, God, Grashdanin is probably what you meant
Never heard of 'a base' before - only knew it as acid or alkali (acidic or alkaline) from school. Googled it and it is showing as base (basic) too, so obviously correct, just personally not come across the term so presume it is predominantly used in America
My understanding is that an alkali is a base which can form an aqueous solution. Since pH only applies to aqueous solutions, I think the correct answer should be alkali (with base being also accepted, of course).
I tried variations of Port of Khartoum, then thought it might be French like Port Louis, so was trying to figure out how Port Rouge etc. might be spelled.
Now I know Khartoum is @400 miles inland, on the White Nile
Words can have multiple meanings and nuances, and in the UK 'alkali' is extremely commonly used, even in education, to refer to what Americans usually call a 'base'.
Oh, I didn't notice extinct *in Europe*, thought you meant really extinct. Considered typing "unicorn", but not many people know that there once really was a unicorn, although it was a rhinoceros and went extinct a lot earlier.
Latin, technically, but it's also the generally accepted English translation of the Russian (of Turkic origin) word това́рищ which was widely used in the USSR (СССР, if you're feeling picky).
I was really proud of sounding out "Ivan" after just a few months of DuoLingo Russian, but then I blanked far too long on how to say "John" in Spanish, a language I've spoken since 1996. Sheesh.
Acid and Alkali is obviously more well known but the saying goes ‘all alkali are bases but not all bases are alkali’
It’s acids and bases.
Alkalis are just bases that dissolve in water
Now I know Khartoum is @400 miles inland, on the White Nile
Acids and bases is correct.
Alkalis are just soluble bases (ie they dissolve in water). So a substance over pH 7 is a base but not necessarily an Alkali…
It’s only an alkali if it’s a base (because it’s over pH 7) AND it’s soluble.
So for alkali to be correct, the question would have to ask what a soluble substance over pH of 7 is.
It's not even Russian, it comes from Spanish
