Ms ( mass of solute): 33,6g
mss (mass of solution): 33,6+192g = 225,6g
__________________
C = ms/mss × 100%
C = 33.6/225.6 × 100%
C = 14,89% ≈ 14,9%

Answer:
group d
Explanation: because it goes back the most amount of years
In order to understand the meaning of the word "indigenous" , we have to break the word as
Indi + gen + ous
Here "Gen" means birth (like genesis: generation of something)
"Ous" means bearing some properties related to something
like marvelous : having property known as marvel.
Thus indigenous means having property of place where birth was taken
Thus it is originating in a particular region
The word root "gen" means "birth," and the suffix "-ous" means "having the quality of something."
Answer:
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the required density by knowing it is calculated by dividing mass over volume:
Therefore, we plug in the given kilograms and liters to obtain:
Which shows the proper scientific notation.

Electronic Configuration of Cu⁴⁺ is written using these two steps;
Step I:
Write the Electronic Configuration of Copper (Cu).
As Atomic Number of Cu = 29
So,
1s², 2s², 2p⁶, 3s², 3p⁶, 3d¹⁰, 4s¹
Rearranging it in order of increasing orbital energy,
1s², 2s², 2p⁶, 3s², 3p⁶, 4s¹, 3d¹⁰
Or,
Cu = [Ar] 4s¹, 3d¹⁰
Step II:
Now, the Cu⁴⁺ ion has lost 4 electrons, So one electron from 4s and 3 electrons from 3d orbital are removed, The resulting electronic configuration becomes,
Cu⁴⁺ = [Ar] 3d⁷
