How many times did Earth orbit the sun between 140 CE and 1543 , how do you figure this up????


If you know how many years that is, the earth orbits the sun once a year.

I hope this helps. Thanks for asking.


How many years is 140 Ce to 1543 ??


We need to know 10 different kinds of gases


Look at the periodic table. Hydrogen, helium, neon, argon, krypton, xenon, radon, fluorine, chlorine, oxygen, and nitrogen IF you want elements. There or literally hundreds of molecular gases; i.e., methane, ethane, propane, butane, ethene, ethyne, propene, propyne, 1-butene, 1-butyne, (some of these have isomers but I didn't list them). I hope this helps.


Matt, You should post your own question separately; that way the answer will come directly to you.


I had this question on my homework too. I found that CE is the same as AD. so when they say 140 CE, they also mean 140 AD. If im thinking correctly, you can simply subtract 1543 from 140 to get 1403. There are 1403 years in between 140 CE and 1543.
I hope this works!

  1. what are the names of all the gases? i need it for my school poster thing i am doing and really really need to know. oh and i need to know any other info about 'gases around us' (or just gases!! tar xx
