Hello!
When aqueous solutions of Li₂SO₄ and NaI are mixed the following reaction occurs:
Li₂SO₄(aq) + 2NaI(aq) → 2LiI(aq) + Na₂SO₄(aq)
The compounds produced from this reaction are all soluble, so no precipitate is formed. We know that those compounds (LiI and Na₂SO₄) are soluble because of the solubility rules which states that salts from Group I elements (Li⁺, Na⁺) are soluble.
Have a nice day!
Answer:
(1s)^2 (2s)^2 (2p)^3
Explanation:
Nitrogen has 7 electrons. Hence, the structure will be,
=>(1s)^2 (2s)^2 (2p)^3
Hope it helps:)
Answer:
size-humans brains are usually larger than animals, shape-some animal brains are shaped very odd, and the cerebrum-that is the part of the brain that makes us human.
There are 1.51x10^24 atomsU in 2.50 mol of Uranium.
This is because a mole consists of 6.02x10^24 atoms. SO with this info,
2.5 x 6.02 x 10 = 1.505 x 10^24
but because we must round, the answer is 1.51 x 10^24
*mic drop*
XD silliness aside, I hope this helped!
