other than the periodic table, are often arranged by their properties
Explanation:
Money, they are arranged by how big or small they are, like coins, with pennies, dimes, and quarters.

Answer:
Fossils are remains or traces from ancient life's that is most likely buried in rocks anywhere in the world. Fossils are basically bones, teeth, shells, nests, leaf impressions, and footprints. That is technically explaining what our planet was like long ago. Some dinosaur fossils have been found. Paleontologists find them almost everywhere. If you don't know what Paleontologists are, they're basically people who study fossils. A lot of fossils are found in sedimentary rocks. Sedimentary is a rock that has been formed from things like sand, mud, and many other kinds of rocks.
Hope this helps.
Answer:
0.93956kg
Explanation:
Equation for the reaction is given as;
P4 + 5O2 --> P4O10
From the equation, 1 mole of P4 produces 1 mole of P4O10.
Mass = Number of moles * molar mass
Mass of P4 = 1 mol * 123.88 g/mol = 123.88 grams
Mass of P410 = 1 mol * 283.886 g/mol = 283.886 g
This means 123.88 grams of P4 produced 283.886 g of P4O10.
How many kilograms of P4O10 would be produced from 410. g of pure P4 ?
123.88 = 283.886
410 = x
x = (410 * 283.886 ) / 123.88
x = 939.56g
Upon converting to Kilogram by dividing by 1000
x = 0.93956kg
