Answer:

John Dalton in 1808 put forward a theory known as Dalton's atomic theory. The main points of this theory are 1)Matter is made up of extremely small indivisible particles called atoms. 2) Atoms of the same element are identical in all respect i.e. shape, size, and mass.... 8)An atom can neither be created nor destroyed.

Based on my scale, I have 35g of aluminum. How many aluminum atoms is this? SHOW YOUR WORK.
Aleksandr-060686 [28]
One mole of a substance contains 6.02×10∧23 particles,
1 mole of a aluminium contains 27 g
35 g of aluminium contains 35/27 =1.296 moles
 Thus, the number of particles will be 1.296 × 6.02 ×10∧23
      = 7.804 × 10∧23 particles,
Hence, 35 g of Aluminium contains 7.804 × 10∧23 atoms

Why is it Xe????????????????
Tamiku [17]

Answer:

Here's what I get.

Explanation:

Ba is element 56. Its electron configuration is

1s² 2s²2p⁶ 3s²3p⁶ 4s²3d¹⁰4p⁶ 5s²4d¹⁰5p⁶ 6s²

That's a lot of writing.

To lessen the work, chemists have developed the noble gas notation.

The core electrons of Ba (listed in boldface) have the same electron configuration as Xe, the noble gas found two atoms earlier in the Periodic Table.

Chemists replace the core electron configuration with the symbol of the corresponding noble gas.

The noble gas notation for Ba becomes

Ba: [Xe]6s².

Answer: It's colder.

Explanation: Well for starters Valparaiso is further away from the equator, and Australia is already really hot. But say that Valparaiso is further from the equator should be good enough.
