Jules verne wrote the book twenty thousand leagues under the sea. if one league - 5.556 km and one furlong - 660.0 feet, how many furlongs did the nautilus travel? (assume the twenty thousand leagues is good for 3 sig. fig.) ball park-550,000 furlong t

The Nautilus travel .

Explanation:

Given: 1 league = 5.556 km

1 furlong = 660.0 feet

To find: 20,000 leagues = ? furlongs

Solution:

20,000 leagues =

1 km = 3280.84 feet

If ,1 furlong = 660.0 feet.

Then, 1 foot =

the answer is definitely c.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
